How To Use A Circular Saw Video
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 over if the cut line is lost. Don’t 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 lines.
- Do not use easels when cutting heavy boards With heavy pieces, it is easier to cut them when they are in place than to cut them into easels. Lay 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 to a level above your chest. Otherwise, you cannot safely hold the saw. For tasks that require cutting at a higher level, you must raise the hand saw.
- Beware of the debris This can happen on the top 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 cut line 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 a wood strip as a guide
Important considerations when choosing the right blade.
If you’re a beginner and don’t use the services of an expert circular saw, choosing the right blade can be a little tricky. There are different types of saw blades to suit different materials, types of cutting and saw blade sizes. Then one of the most important characteristics when choosing is the diameter and type of blade. You just need to make sure it is compatible with your circular saw model.
Here’s a quick guide to help you find the right sheet:
- Hand saws accept smaller blades, typically 4 to 7 inches;
- The saw will require a 7-10 inch diamond blade;
- Table saws require 10 or 12 inches, and table saw blades must have a carbide tip;
- 14 ” blades are commonly used for cutting metal.
Another important feature is revolutions (or revolutions per minute). For example, smaller sheets have higher rpm and larger sheets have lower rpm. The recommended saw blade speed should be lower than the recommended blade speed. Note that a saw’s RPM does not directly indicate its cutting speed, so higher RPM does not mean it will cut faster.
The diameter of the blade will affect the speed because the edge of the larger blade will move faster compared to the edge of the smaller blade as it covers a greater distance at the same time. On the other hand, do not rush to select a larger blade, as you must also consider the desired cut quality. Therefore, when looking for the right RPM indicator, consider the material you will be working on.
To do this, you must calculate the SFM, which is Surface Foot per Minute. The formula is as follows:
SFM = (diameter / 12) O RPM
Typically, for wood-based materials you will need an SFM of 5000 to 8000, and for metals less than 1000.
Also look at the cut line indicator when choosing a tool. This is so you can see where your sheet is going while cutting. Without this, it will be more difficult for you to cut straight line. The clip indicator is usually found on the motherboard and looks like two small notches. However, in some cases, you may not be able to see the crop indicator. For such cases, a small window would be helpful to show you where the sheet is, so look for it. Feel free to grab the tool and check if it feels comfortable.
Next take a look at the motherboard. What material is it made of? Magnesium base plates are more stable, but they can break if you drop the saw. On the other hand, the aluminum base plate can bend when you need it most, while the plastic base plates are resistant and impact resistant.
Regardless of the material, the base plate must be flat in length and width and have a straight edge. At the end, take a look at the guard. Fences with sharp or rough edges can get stuck on wood surfaces during cutting and make it difficult to lift.
When it comes to what you are going to cut, you should also pay attention to the type of blade. Different types of materials work better with different types of blades. For example, there are blades designed for cutting wood, plastic and acrylic, metal and several materials. Here are some of the types you might need:
- Rip Cut is wood cutting; Consequently, cutting blades are designed for cutting along the grain: these blades have fewer teeth, specially designed for aggressive cutting;
- The cut-to-length blade is designed for cutting grain and has 40 to 80 teeth for a clean cut;
- Combination blades are used to make incisions both crossed and torn, as they have groups of teeth separated by the throat.
Since teeth make a larger incision than the disc itself, its shape and number must be considered. This is another aspect of the blade that will affect your cutting performance. The more teeth there are, the more accurate the cut will be. In addition, the shape of the teeth determines the quality of your cut. For example, an alternative top bevel type is suitable for fast cuts in rough wood that are along the grain. Multi-material blades are good for cross-section, and radial arm blades have a negative angle to avoid automatic feed.
How to care for your blade
No matter which type of blade you choose, it will require the right attention to give you accurate results and allow you to work safely. Here are a few rules to follow:
- To protect your teeth from shards or breakage, you should try to avoid contact while storing the blade.
- Sharpen the blade regularly and ideally you should have an extra blade on hand to make sure you can replace the blunt blade immediately when needed.
- When doing woodwork, always place the saw on a level surface between cuts; Never lay it on the ground.
- Never remove the chain saw from the board and never try to reverse it while working. Always stop the blade before lifting it.
Cleaning is very important to keep the blade in good condition and prolong its life. Do not use aggressive cleaning materials such as wire brushes or steel scrapers. The blades withstand tremendous force and the use of such materials can compromise the integrity of the blade. Use better quality plastic cleaner or brass brush if needed.
Why is cleaning so important? In the case of a saw blade, it is not just a matter of hygiene. During use, the blade is contaminated with pieces of juice, resin, dirt and dust that adhere to the blade body. If not removed, they add more friction, which in turn makes the blade easier to heat up during use. In addition, dirty blades are cooled more slowly, resulting in faster shutdown and ultimately distortion of the blades.
Keep in mind that even the sharpest blade will be sharp enough to cut through human flesh, so take appropriate precautions while cleaning.
Quick start checklist
Is this the first time you are going to do carpentry? If so, it means that you still don’t have the required tools. We recommend trying a versatile and affordable tool that feels comfortable in your hands. It will help you gain some experience, and then you can choose specific model or models according to your needs and requirements.
When you are a beginner, it is best to start with simple woodworking and move on to more complex tasks when you feel more secure. Once you have the tool at hand and are ready to launch it, the best way to overcome your fear is to run a few tests to get a feel for how it works. After that you can start your first job.
It is very important to follow safety guidelines when using a circular saw, so here is a quick checklist to read:
- There are two important points to keep in mind: safety and protection. Although modern saws are designed to be compact and safe, this tool still requires your full attention.
- Check the saw before each use to make sure it is not damaged. Make a safety check of the blade and replace it if you see broken or broken teeth.
- Inspect the cable and please remember to unplug it before performing any blade operations such as cleaning or replacing.
- The quality and speed of cutting depends on the condition of the blade. For best results, make sure the sheet is smaller? Inches beyond the edge of the board. Adjusting the blade too deep can force the saw joint and push back.
- Never use a rusty or damaged blade! Sheet selection is important and you will find more information on how to choose a good sheet for joinery below.
- Check if the blade is sharp enough and sharpen it if necessary. A sharp blade is safer and works more efficiently. On the other hand, a dull blade could join the tree and overheat.
- Make sure the blade is seated correctly and that the guard moves easily to cover the blade when not in use.
- Be sure to place the saw in a safe position. There are no hard and fast rules about cutting direction, but you should keep the saw motor oriented towards most of the board; This will provide better support for the saw blade.
- Make sure the blade is turned correctly.
- Check your sheet or board to see if there are nails or knots before cutting.
- Remove all cables from the cutting area and make sure they are not damaged.
- Wear a mask or safety goggles to protect your skin and eyes from damage.
- Long sleeves in addition to gloves (gloves are essential) provide extra protection for your hands.
- There is a risk of inhaling dust, so using a respirator or mask may be beneficial.
- Hearing protection may be considered as some jobs may not be as quiet.
How to use a circular saw: secrets and tricks
Learning how to use your circular saw safely and effectively gives you a rewarding and interesting hobby. The circular saw is a sophisticated and effective tool that can help you create a range of beautiful products, from shelves to art. For beginners, a circular saw may seem more complicated and less convenient than a puzzle, but don’t worry! We help you learn to cut with confidence, safety and enjoy your skills.
First, let’s see what a circular saw is. In fact, it is a blade with a protective guard around it, driven by a motor that creates a circular motion for cutting. Generally speaking, circular saws can be divided into two types: side saws and screw saws. The side mechanism is compact and the motor is located along the blade.
Due to its smaller dimensions, this type of saw is less powerful than the larger models. For the same reason, it is less durable, so if you choose a tool for heavy use, this is not the type you want. Buy a side mechanism in case you need a light and simple tool for occasional use.
The worm saw is larger and the motor is located behind the blade. This saw can handle hard materials without overheating. Overheating should be avoided for safety reasons: when the saw slows down during heavy work and heats up, the blade dulls quickly and the cut quality drops dramatically. In the end, the sheet can kick and hurt you.
Useful cleaning products.
For effective and safe cleaning of the blade, you can consider a special liquid designed for cleaning the blades. You can also try household cleaners (non-aggressive), but for stubborn dirt this may not be enough or requires additional cleaning.
Use a nylon cleaning pad for cleaning. If you are the proud owner of a coated blade, always make sure your cleaning supplies and cleaning materials are comfortable with the blade layer. It doesn’t matter if you use an aerosol cleaner, liquid, or just soap and water, it is very important to dry the blade after cleaning it. And, of course, the last important cleanliness parameter is regularity. It will help you keep the blade sharp and safe for longer.
Among the other tools in his workshop, the circular saw is not the easiest, but it is durable, economical and can be used for a wide variety of applications. It will take some time to gain experience and teacher confidence, but eventually the circular saw will become one of your devotees’ assistants in the carpentry business. From plywood to stone, any material will be impossible for you. Observe safety rules and carpentry will become your favorite hobby.

For clean cross-cutting of bulky wood species, decorative plywood and other sheet and panel materials, change the standard 24-tooth blade, which is equipped with most models, to a blade with 50-60 teeth. And for most cuts where quality requirements are not very high, use a 40-tooth blade. How to work with therefore use the circular saw before starting to saw. And only for rip sawing bulky wood species, reinstall the standard 24-tooth blade.
Get rid of chips in one of three ways
Teeth saw blade spinning forward and upward. The underside of the workpiece, where the teeth enter the material, almost always remains clean, without chips. On the contrary, the top side usually happens to be so chipped that it cannot be used in visible places of the product (compare three photos with different degrees of chipping). How to work with a hand saw before starting to saw with a circular saw is as follows. 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 tricks to keep the edges of the cut clean.

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. By choosing a board with a circular saw, dissolve a board how to make it from boards. Smoothly plunging into a rotating disc and sawing through it, you get an anti-splinter pad, the width of the spill in which will exactly match the thickness 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.
3. Make a guide bar
This guide bar will not only help to deal with chipping, but it will also simplify your cutting work without having to resort to calculations. Make it as shown in the figure. A ruler for a hand-held circular saw or how to work with a circular saw. 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 stop 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. How to use a circular saw for sawing; how about the repair. 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, as on the other edge of the cut, where the fibers are not pressed, chips will appear.
