How to use

hand-held, circular

Circular saws are designed for straight cuts, so they are easy to use. The workpiece itself does not have to be fixed motionlessly, it is enough to press down with your knee to the stool and cut it off in the right place. It should be noted that it is important for the job to choose the right saw blade. To do this, you need to know three parameters:

  • disc diameter;
  • bore diameter;
  • suitable disc type.

Types of disks by purpose:

  • A. chipboard, aluminum, plastic.
  • B. universal discs for wood with high cutting quality.
  • C. for hard and soft wood species, as well as MDF, chipboard.
  • D. universal blades for fast and rough cuts.
  • E. for high quality cuts in softwood.
  • P. for fast and coarse cutting of softwood.

How to use a circular saw

The most popular material for home craftsmen is wood, and nothing better than a circular saw for working with wood has not yet been invented. Cutting “lining” for a bathhouse, a picket fence for a fence, boards for benches and a booth for a dog. all these works are updated during the summer period. But the work process should be approached very carefully, because a circular saw is a traumatic tool. One wrong move and you risk being left without fingers.

Safety engineering

Conventionally, all circular saws can be divided into hand-held and circular saws. The latter are small machines with a disk fixed in them, in relation to which you move the workpiece.

To work with a hand-held circular saw:

  • Check its serviceability (you can just turn it on by weight).
  • Check that the type of disc is suitable for the material being processed and that it is securely attached to the spindle.
  • Check the integrity of the disc, the absence of cracks and the presence of all victorious soldering on the teeth.
  • Use a face shield or at least goggles.
  • Do not turn on the hand-held circular saw with the blade against the workpiece, the blade must be free.
  • Do not press down hard on the tool to avoid overloading it.
  • Clean the saw after work, especially the moving parts.

To work with a circular saw:

  • All circulars are made under right-handed people, so position yourself to the left of the workpiece.
  • Before starting work, check that there are no nails or other metal elements in the header.
  • If there are large knots in the wood, at the moment the disc approaches them, you need to slightly slow down the rate of advancement of the workpiece due to the hardness difference.
  • If it is necessary to replace the disc, the machine must be completely de-energized by removing the plug from the socket.
  • Before starting work with the circular saw, you need to start the blade and wait until it picks up speed. It is forbidden to immediately feed the workpiece, and even more so to abut it against a static saw blade.
  • You need to move the workpiece using special pushers. As a last resort with hands on either side of the saw blade, but not on the same axis with it.

Using these simple rules, you can easily use a circular saw in your home workshop.

What discs to take

The saw blade is the most important part of the circular, the working body for which it is made. The entire design of the machine is also tied to it, so you need to decide in advance which discs we will use in work, and how to choose the one you need in absentia (online) according to the designations on it or in the description.

Saw blade types and designation systems

The most common are 2 notation systems. According to the first (item A, pos. 1 in the figure), the following are sequentially indicated:

  • diameter of the disc at the tops of the teeth, mm;
  • cutting width, mm;
  • mounting (landing) hole diameter, mm. Typical (default) tolerance of 0.05 mm is not specified;
  • atypical landing tolerance (possible);
  • number of teeth;
  • with the letter T or with a pictogram. the presence of hard-alloy soldering on the teeth;
  • rotation speed. operating (nominal) just in numbers, the maximum allowable with the prefix max.

According to the second system, it is necessary, in numbers separated by hyphens, to indicate the size of the disc: diameter at the bases of the teeth, their number, and the bore diameter (the default tolerance is the same). For example, 190-36-30 in item B pos. 2 means a disc with a diameter of 190 mm (there will be 200 at the tops of the teeth) with 36 teeth for a fit of 30 mm. The speed is indicated separately, but here it is the maximum by default; working 10% less. The rest of the parameters are indicated either by symbols (item B, pos. 2) or textually. The minimum rotational speed at which the proper cut quality is still ensured for certified discs with stabilizing slots (pos. 1, 2, 4, 5) is 50% lower than the working speed, and for solid discs. 25% less.

There are quite high-quality “off-system” disks on sale (pos. 3-5). But in all cases, simply “on wood” (pos. 2-4) denotes the corresponding TU industrial wood, plywood, chipboard, laminate, etc. sufficiently high-quality wood materials. Sawing with such a disc an unseasoned raw tree is dangerous. it can jam and fly apart. For cutting wild wood, special discs are produced with the designations Forest (forest, pos. 5), Wildwood (wild tree), Timber (timber), Log (log), etc. Discs with such designations are used in stationary pendulum saws, circular sawmills and other equipment for sawing raw wood.

Finally, many unmarked saw blades go on sale, pos. 6 in Fig. In general, they saw, but with them you need to be more careful: the linear speed of rotation of such a disk is better not to give more than 40 m / s. To get the rotational speed from it (for calculating the gear), we measure the diameter of the disc at the bases of the teeth D (in mm), and calculate its working rotational speed as 60 (40,000 / (3.1415xD)). For example, the working speed of rotation of a “turbid” disk by 200 mm will be 3815 rpm; better take 3500.

Why three in one, not a separate tool

Several carpentry accessories in one body. compact, comfortable and safe

The advantages of combining several carpentry accessories in one machine are obvious:

  • Order in the workshop. All tools are collected in one box, which means that nothing is lying around;
  • No extension cords. Only one common cable will extend from the workbench. That is, you can forget about the bundle of inconvenient wires;
  • Everything is at hand. Everything is nearby in the availability zone, which means that you can focus on work without being distracted by the search for the necessary tool;
  • Affordable price. A home-made combined mini-machine will cost less than buying a factory-made multifunctional machine.

What is a circular saw for?

It is designed to cut softwood and hardwood boards with a moisture content of no more than 50% and a thickness of no more than 64 mm. It is allowed to cut plywood, aerated concrete, chipboard, asbestos-cement and cement-particle boards.

Tips and tricks to help you achieve the best results.

Once you’ve gained some experience and are good enough to get started on more challenging and sophisticated work, it’s time to start learning the secrets to help you improve your skills and create masterpieces of wood art. For a safe teacher, a good circular saw can go through any material: foam, plywood, PVC. With a diamond blade, you can even cut stone! Circular saws can be configured for split or beveled cuts and can even replace a table saw in many jobs.

Here are some tips and tricks to keep in mind:

  • Start again if the cut line is lost. Do not try to get back on the line as it will be difficult, especially if you are a beginner. Remove the blade and start over. After a few tries, you will effortlessly cut beautiful straight mowing lines.
  • Don’t use easels when cutting heavy boards. Heavy pieces are easier to cut when in place than cutting into easels. Place the board on your toe and lean towards it, but make sure you cut more than 10 inches from your foot.
  • Avoid pinching To cut leaves, support must be provided to avoid kickback, which usually occurs when the saw blade gets stuck in the cut. When cutting on ramps, be sure to place the saw outside of a pair of ribs. Position the board or sheet so that the longest part does not fall off when cut.
  • Continue cutting to a safe level and avoid cutting above your chest. Otherwise, you will not be able to safely hold the saw. For tasks that require cutting at a higher level, you must raise the hand saw.
  • Watch out for debris. This can happen on the top surface of a board or sheet and can be frustrating if you are driving through expensive forests. To avoid this, place the table with the visible surface down. So in this case, if fragmentation occurs, it will affect the back. You can also mark the line for the cut with a utility knife to help you make a smooth cut. For a nicer appearance, support the board fully so that it does not allow a falling object to attract a shard of wood.
  • Cut the same pieces. If you need to cut multiple pieces of the same size, place the sheets on top of each other and make sure all the edges are aligned. Then hold or secure the stack to prevent it from moving and cut all sheets at the same time.
  • When you need to cut straight line, you can use a metal ruler or wood strip as a guide.

Assembling a complex machine

Depending on the components you choose, you can get a higher power machine. To assemble the machine with your own

hands you will need:

  • Electric motor with a power of about 900 W. If you have to cut pipes regularly, you can choose a more powerful electric motor;
  • Metal sheet;
  • Metal corners;
  • Channel;
  • Hinge groups;
  • Angle Grinder;
  • Welding device;
  • File;
  • Spring of impressive power.

  • A homemade bed can be done by hand using adjustable supports, metal corners and bed racks.
  • A sheet of durable metal acts as a working surface. In this table-sheet you need to make holes and process them with a file.
  • To weld a pendulum rack for a future machine, use channels and a welding machine. The structure is installed on a metal sheet. Approximate rack height. 80 centimeters.
  • The support for the electric motor is made of a metal sheet in the form of a fixed plate. Be sure to install the stand on the hinges.
  • The stabilizer of the electric motor of the miter saw is a powerful spring. If you managed to find one, it is quite possible to refuse from belts and a swingarm.
  • Using the eyebolt, you can tension and adjust the belts. The pendulum can be made of metal to make the structure reliable, durable.
  • Select the disc of the required diameter with the operating tool. For domestic purposes, a saw blade with a diameter of 400-420 millimeters is usually sufficient.
  • Be sure to provide for the presence of protective covers, since the assembly of such a machine is accompanied by a certain degree of danger.

Assembling the table saw

Assembling a circular saw with your own hands at home is not a very difficult job, you just need to prepare all the necessary parts and tools, choose a structure and follow the drawings and instructions exactly.

The table circular saw is easily assembled from a regular one. The finished fixture will have a compact size.

To do this work, it is necessary to assemble from a thin tube or rod of 18. 20 mm made of metal, the frame to which the lever is attached.

The part of the structure located below must be bent in the direction of the cut. This element is attached to the table with self-tapping screws.

Make sure the device stand is stable. Swinging the saw while working can be very dangerous because any careless movement can lead to loss of fingers or hands.

It is best to make your table out of metal by fixing its legs to the floor.

A lever made from a tube in the shape of the letter “T” should be placed on the cross member. The lever should be free to scroll.

The part is cut across into several sections. After completing the installation of the structure, all elements are connected using clamps.

A homemade mini circular saw with your own hands is attracted and fixed with clamps to the vertical extreme part.

The assembled circular saw can be used in the home workshop as a cutting tool. Before starting work, insert the cutting wheel into the angle grinder.

To process thick boards, you need to use a full-fledged apparatus. The carriage is used to trim the elements. It is assembled from several beams attached to the base and performing a guiding function.

Having understood how to assemble the device, you need to select materials and tools suitable for the job. At a minimum, you need a working angle grinder and various consumables.

But to assemble the device with your own hands, you need special skills. If you do not have the necessary skill, then it is better to purchase a circular saw, in the correct, reliable and safe operation of which you can be absolutely sure.

The described method allows you to assemble a small circular saw that can be used in a home workshop or your own shed.

How to work with a circular saw

Start with a good drive

For clean cross-cuts in solid wood, decorative plywood and other sheet and panel materials, replace the standard 24-tooth blade, which is available on most models, with a 50-60-tooth blade. And for most cuts where quality requirements are not too high, use a 40-tooth blade. And only for ripping solid wood, reinstall the standard 24-tooth blade.

Get rid of chips in one of three ways

The saw blade teeth rotate forward and upward. The underside of the workpiece, where the teeth enter the material, is almost always clean and free of chips. On the contrary, the top side is usually so chipped that it cannot be used in visible parts of the product (compare three photos with different degrees of chipping). Therefore, if possible, always lay the sheet or strip face down for cutting. And if you have to cut to the right side, use one of these techniques to keep the cut edges clean.

How To Use a Circular Saw

Pre-pruning

Cut two times instead of one. The first shallow cut will cleanly cut surface wood fibers so they will not be ripped up in the final cut.

2.Use an anti-splinter pad

Attach a hardboard plate to the base of the circular saw to press down on the surface wood fibers, especially on materials covered with firewood veneer, and to prevent chipping where the teeth of the blade come out of the material. Smoothly plunging into a rotating blade and sawing through it, you get an anti-splinter pad, the width of the shed in which will exactly match the thickness of the saw blade. It will help minimize chips.

Attention! Be extremely careful when working with such a pad, as it prevents the protective cover from covering the disc from below.

Make a guide rail

This guide bar will not only help to deal with chipping, but it also simplifies the cutting work without having to resort to calculations. Make it as shown in the figure. Adjust the width to match your saw. We made a guide rail with a mine about one and a half meters for cutting plywood sheets. The distance between the edge of the base and the fence should be 10-12 mm more than the distance from the saw blade to the edge of the sole of your saw. File the edge of the guide bar by pressing the sole against the stop. Now one edge of such a tire will act as a splinter pad, pressing the fibers from above. Before cutting, put the tire on top of the future part, since chips will appear on the other edge of the cut, where the fibers are not pressed.

Bench for circular saw

The most common bed can be made from an old dining table or thick wood plywood and a few slabs. Holes are drilled in the tabletop to fix the circular itself and an incision is made according to the size of the saw blade. It is important that the bed cover is not made of thin material and that it can withstand the load of the workpieces. For fastening, it is recommended to take countersunk screws so that they do not protrude above the surface and do not catch the material during processing.

Security

It should be remembered that such a stationary circular is still made by hand. Therefore, in order to avoid injury, it is better to secure your work as much as possible. You can install protection in the form of a special movable casing located above the edge of the disc.

It is also better not to make a circular with a drill. Although many craftsmen advise this method due to its simplicity and economy, at the slightest mistake, serious injury cannot be avoided.

How to make a circular saw out of a circular saw. instructions

Any owner of a private house or summer cottage has ever necessarily thought about purchasing a stationary circular saw. However, in most cases, the purchase is postponed indefinitely: the cost of such pleasure exceeds two or three tens of thousands, which is often beyond the means of the average citizen of the country.

But even if you are not ready to spend that kind of money on a stationary saw, you can make one yourself from a hand-held circular saw. For professional use, such an invention may not be suitable, but dissolving the boards, quickly and conveniently cutting the beams or sheets of fiberboard is quite real.

To make a homemade circular, you will need:

  • Washers, nuts, bolts;
  • Metal strip;
  • Angle Grinder;
  • Metal corner;
  • An old table or a thick sheet of fiberboard;
  • Engine.

Engine

When selecting an engine, it is imperative to pay attention to the shaft speed. You can, if desired, independently change the number of revolutions using a belt drive. The motor must be powerful enough, so there is no need to save several thousand and make it from the first thing that comes to hand, be it a drill or a mixer.

The main indicator of a homemade circular saw is the maximum thickness of the sawn bars. Usually, for home use, a cut of 1.5-2 cm is enough, but if this is not enough, then an additional lifting disc mechanism can be installed. This will make the system more complex, but will allow you to deepen the cut to the required level.

Base

On the question of how to make a circular saw out of a circular saw, the most important thing is to remember about the functionality of the base. It is best to install the table on a high-quality and rigid base that does not bend or wobble. This ensures safe working and an even cut.

If possible, it will be good to weld it from a metal corner in accordance with the dimensions of the already finished countertop. In extreme cases, it is permissible to build a base like a wooden underframe.

In custody

It may seem that the design is too simple and uncomplicated, but this does not detract from the merits of such a primitive circular. It, just like its factory counterparts, does an excellent job of sawing small wooden blocks and allows you to perform carpentry operations with boards.

By the way, your homemade machine can be made multifunctional and you can also attach a plane to it. This saves space and makes the tools easy to dismantle.

What can be done with a hand-held circular saw

Manual circulars are suitable for a whole list of jobs:

  • facing several wooden blanks at once, which lie in the same plane;
  • trimming wide boards, for which a pendulum saw cannot be used (you will need a parallel stop);
  • trimming boards when laying floors;
  • facing workpieces at an angle (you can use a guide or do without it);
  • longitudinal cutting of workpieces at an angle;
  • sampling a quarter in a board or bar;
  • cutting sheet materials using a guide;
  • cut of organic glass and plastic;
  • using the hand saw as a stationary saw by mounting it to the table.

Preparing the workplace for work

It is necessary to remove all unnecessary items from the desktop. There should be no tools, keys or consumables. In addition, you need to provide a free approach to the table. The floor in the work area must be dry to avoid accidental slipping. The machine must be grounded.

There are also requirements for the operator’s work clothes. Clothes need to be tucked in so that there are no fluttering ends. If you have long hair, pick it up and hide it under a hat. Wear safety goggles and a respirator. Wearing ear protectors is recommended as the noise level can be quite high when working with a circular saw.

Before starting the saw, you need to check it for defects in the saw blade, make sure that it is secured properly. Check if the riving knife is installed correctly, and then check that the guard is working properly.

If your saw has a short cable, you may need an extension cord to help you navigate the work area comfortably. It is advisable to use a circular saw with a soft start function so that the tool does not jerk when starting.

Setting up the circular saw before work

Before you start sawing, you need to install the blade and make sure it is firmly held in place. The cover should open and return to its original position without any resistance. It is also worth checking to see if the riving knife is properly positioned. Then run the saw in idle mode for 10 seconds to make sure it is working properly.

To set up the circular saw, you need to adjust the required position of the guide pin and cutting blade using a vernier caliper. When checking the position of the teeth in front and behind the disc, the difference should not be more than 0.05 mm. You also need to install the riving knife and blade so that they are on the same line. For their precise adjustment, special washers are used. The fixing bolts must be tightened well to keep the tool and table less vibrating.

How to cut a board straight with a circular saw

Unlike a stationary pendulum saw, it is more difficult to make a straight cut with a circular saw. This will not be a problem if the board or timber is narrow, but to cut a wide workpiece or when cutting longitudinally, you need to know how to make the cut as accurate as possible. To do this, you need to adhere to the following sequence of actions:

  • There should be nothing under the piece of material that you will be sawing. The circular saw blade should not cut anything else. For example, never place your board on a concrete floor. use trestles or a saw table instead.
  • Mark the line along which the saw blade should go. Use a tape measure, ruler or square for this.
  • Adjust the cutting depth. The blade should barely protrude beyond the workpiece. For example, if the thickness of the workpiece is 40 mm, the cutting depth should be 45-50 mm.
  • Check the condition of the guard. It should rise gently when the saw is lowered onto the workpiece, and immediately close the working part when it is raised.
  • When starting to cut, look at the front right edge of the blade and align it with the mark on the material.
  • Look at the right guide of the circular saw for right angle cuts, and the left guide for 45 degree cuts.
  • Start cutting the material. Watch the guide at all times to make an even cut.
  • Keep the saw base flat on the material at all times.
  • Push the saw hard enough to cut, but don’t push too hard to overload the engine. The hardest woods should be cut with minimal effort.
  • After finishing cutting, make sure that the guard is back in the closed position.

Correct operation of the circular saw

The hand-held circular saw is one of the most important tools in the woodworking industry. It significantly increases the speed of working with wood or plastic, sheet material, planks and timber. It is most commonly used for cross-cutting, but it can also be used for sawing along the grain of the wood. In this article, we will tell you in detail about the range of use of circular hand saws, setting them up before work, work techniques and safety rules.

Circular saw safety

Circular saws have a relatively high risk of injury, therefore safety precautions must be followed when working with them.

Safety tips when using the saw

Before starting work, run the circular saw with no load. As you cut the material, observe the following rules and recommendations:

  • When starting work, you should stand on the left side of the machine so that if the workpiece is accidentally thrown out, it will not hit you.
  • Make sure there are no nails, pins, pieces of dirt or concrete in the workpiece or on the surface of the workpiece that might interfere with the cut.
  • It is forbidden to transfer objects over a working circular saw.
  • If there are knots or cracks in the wood, drive the saw more slowly when approaching them.
  • When changing the saw blade, be sure to unplug it.

Preparing the workplace for work

It is necessary to remove all unnecessary items from the desktop. There should be no tools, keys or consumables. In addition, you need to provide a free approach to the table. The floor in the work area must be dry to avoid accidental slipping. The machine must be grounded.

There are also requirements for the operator’s work clothes. Clothes need to be tucked in so that there are no fluttering ends. If you have long hair, pick it up and hide it under a hat. Wear safety goggles and a respirator. Wearing ear protectors is recommended as the noise level can be quite high when working with a circular saw.

Before starting the saw, you need to check it for defects in the saw blade, make sure that it is secured properly. Check if the riving knife is installed correctly, and then check that the guard is working properly.

If your saw has a short cable, you may need an extension cord to help you navigate the work area comfortably. It is advisable to use a circular saw with a soft start function so that the tool does not jerk when starting.

What can be done with a hand-held circular saw

Manual circulars are suitable for a whole list of jobs:

  • facing several wooden blanks at once, which lie in the same plane;
  • trimming wide boards, for which a pendulum saw cannot be used (you will need a parallel stop);
  • trimming boards when laying floors;
  • facing workpieces at an angle (you can use a guide or do without it);
  • longitudinal cutting of workpieces at an angle;
  • sampling a quarter in a board or bar;
  • cutting sheet materials using a guide;
  • cut of organic glass and plastic;
  • using the hand saw as a stationary saw by mounting it to the table.

Safety tips when using the saw

Before starting work, run the circular saw with no load. As you cut the material, observe the following rules and recommendations:

  • When starting work, you should stand on the left side of the machine so that if the workpiece is accidentally thrown out, it will not hit you.
  • Make sure there are no nails, pins, pieces of dirt or concrete in the workpiece or on the surface of the workpiece that might interfere with the cut.
  • It is forbidden to transfer objects over a working circular saw.
  • If there are knots or cracks in the wood, drive the saw more slowly when approaching them.
  • When changing the saw blade, be sure to unplug it.

Why is it profitable to buy this particular manual circular?

The body of the circular saw is made of non-toxic polymer materials.

For the convenience of work, the plastic case in the touching places of the hand is treated with a special material to ensure anti-slip.

For convenience, the hand circular is equipped with an additional front handle. This handle can be operated with two hands.

The saw blade start button is conveniently located in the front handle. Turning on / off the manual circular for work possible with one hand.

On the left, there is also an additional lock button. The buttons are made of quality plastic with a protrusion for a secure grip with the fingers of the hand to prevent slipping.

The switching mechanism is made in such a way that it was possible to turn on without fixing the work and with fixing the work in the case of stationary use of a circular saw or for a long longitudinal cut of a board or chipboard without turning off.

The top stationary guard for the circular saw blade is made of robust steel. Hammer paint.

The lower protective casing is movable and can be pushed back either with a special lever or when the circular saw casing touches the edge of the cut surface. After the end of the cut, the casing, under the influence of the spring, leans back, thereby closing the cutting part of the cutting disc.

The locking mechanism of the cut-off wheel is in the form of a screw that grips the plastic spacer rings. A regular open-end wrench is used to change the disc.

Maximum cutting disc diameter 235 mm.

The cutting depth with this blade size is 72 mm maximum.

For the convenience of cutting at different angles of inclination, the circular hand saw is equipped with an adjustable platform with a maximum angle of inclination of 45 degrees.

The platform of the circular hand saw has a graduation scale for ease of use. Adjustment is made by loosening (tightening) the adjusting screw. The adjusting screw is built into a comfortable plastic handle.

The handheld circular saw is equipped with an advanced cooling system, which ensures the durability of the electric motor. This function makes the handheld circular saw a professional tool.

What can be done with a circular saw

The principle of operation of this unit is based on the rotation of the cutting disc by an electric motor. The saw design is presented in two versions: manual or stationary. An important difference between these two versions is that the force from the engine to the disk in the stationary model is transmitted through the belt, while in the manual model the disk itself is fixed on the shaft. The saw can cut wood both along the fibers and across them, cut out a quarter. The tool can be used to saw off soft metal, plastic, if you use special discs.

Circular and circular saws as indispensable helpers in your farm. How to saw and tune the tool?

The forerunners of modern automatic saws were tools made of stone, bones, on which jags were applied from one edge. The beginning of this instrument was laid in the fourth millennium BC. They are used both in household work and in the creation of various works of art.

Then, stone and bone were replaced by copper, iron, steel. The first power saws appeared in Germany in the XXIV century. Electric saws became widespread only in the 20th century.

Setting up the circular saw

Before starting work, you should:

  • put the disc;
  • make sure that it is securely fastened;
  • make sure that the protective cover opens freely and returns to its original position when the handle is released;
  • check the correct installation of the riving knife;
  • make sure the saw is working properly by holding it in the on mode for 10 seconds without load.

It is quite easy to adjust the saw before starting work. This requires:

  • Adjust the position of the guide slot on the table and disc using a caliper, aligning the guide slots on the blade. When checking the tooth in the front and back of the blade, the difference should not exceed 0.05 mm
  • Check the parallel stop with a groove or slot. Here the offset should also not be more than 0.05 mm.
  • Make sure to align the riving knife with the blade so that it is on the same line as the blade. In case of mismatch, a more accurate adjustment is achieved by rotating the washers
  • Tighten the mounting bolts securely to protect the table and the machine from vibration

What is a circular saw for?

It is designed to cut softwood and hardwood boards with a moisture content of no more than 50% and a thickness of no more than 64 mm. It is allowed to cut plywood, aerated concrete, chipboard, asbestos-cement and cement-particle boards.

  • Make the initial cut 3-5 mm.
  • Continue sawing without stopping all the way through the blade.
  • Use duct tape at the cut to avoid chipping.
