How to drill strictly vertically with a drill. How to choose

How to drill perpendicular hole by yourself?

Quite often it is not a problem that the drill slips off the mark and the hole is not made in the right place. To fight this can help cardboard scotch tape glued to the top of the tree. Also sometimes similar difficulties appear in this case if one has to work with a very thick drill bit. Then you should first make a hole in the material with a narrower drill bit, and then drill against the mark you made. Pay attention to the quality of the sharpening. If the edges are not sharp enough or are not sharpened flat, you may have problems with precision drilling.

drilling fineness for various materials. Recommended reading. What speeds are required for drilling

One of the fundamental drilling parameters is the RPM. The speed at which you need to drill depends on the type of material and the type of drill. There is a general rule: The harder the material and the thicker the drill bit, the lower the RPM should be. As for specific figures, you can see them in the table below.

drill bit cross section, mm soft wood hard wood plastic (acrylic) copper aluminum steel Notes
1.5-4.8 3000 3000 2500 3000 3000 3000 When drilling metal that is thicker than 3 cm, oil the drill bit frequently.
6.4-9.5 3000 1500 2000 120 2500 1000
11.1-15.9 1500 750 1500 750 1500 600
17.4-25.4 750 500 400 1000 350

This table is created for common twist drill bits. For specific options (Frostner drill, etc.д.) drilling speeds for different materials are slightly different from those shown above.

How to drill deep holes properly.

Modification of the auger drill bit, start by stripping the guide screw. Then blunt the edges as shown in the photo below. This modification will provide a weak “bite” and without being too aggressive helps to drill deep holes in a straight line.

Alignment. Straight metal rod, aligns V-block with control hole.

Another problem to drill deep holes, set a straight hole as a guide. A drill press would seem to be the logical tool with which to drill straight holes, but it has a limited drilling depth. But the drill still plays a big role in this operation and serves to drill a pilot hole. I start drilling the hole with a drill bit of a smaller diameter, and gradually increase the hole to the diameter that I plan to use.

When the drill rests the chuck on the V-block, remove it and drill a hole the full length of the drill bit or the depth of the hole.

As soon as the guide hole is ready, install the drill bit with the desired diameter, and secure the workpiece on the workbench with clamps. Remember that even with a good and tight hole, an off-center drill bit during drilling will not keep it away. To help guide the drill into the hole along the axis line, a V-block is made. To adjust the alignment, take a long metal rod and insert it into the pilot hole as shown in the photo above, align the V-block with the rod in the bar and secure with a clamp. I start drilling the hole with the drill on low rpm. Don’t be lazy and often clean the drill from sawdust clogging the screw, it makes the drill rotate easily and helps to guide the drill properly. Once the drill chuck hits the V-block, remove it and continue drilling the hole. Doing these simple and uncomplicated things will give you great results.

Drilling a hole straight through at a 90 degree angle is no easy task. It may take a lot of effort to keep the drill level and upright. BullseyeBore suggests doing it with several laser concentric rings.

The BullseyeBore drill uses a simple red laser to project three rings onto the surface where you are going to drill. In order to keep the drill as level as possible during the process, observe the three rings. The two inner ones will stay in the same position no matter how the drill is tilted, while the outer one can move. By aligning the biggest ring with the smaller two, you get the drill to be perfectly vertical and the hole will be just perfect.

Additionally, the concentric circles can indicate the depth of the hole. The distance between the large and medium circles will be just an indication of the drilling depth. If in the beginning there will be such a picture:

In the middle of the process, the circles will get closer together:

The nozzle looks like a small, clear disk with a connector for easy installation into any drill. Lasers, optics, and batteries are already built in. The disk is sleek, lightweight, and impact resistant.

Producers are now developing a model where all the hardware will be implanted into the drill chuck.

Drilling the hole with a feather drill bit

At first glance, when faced with the question of how to drill a hole in wood in most people there is no doubt: think wood is not metal and is easy to drill. Yes, that’s partially true if you want to make a trivial hole in the wood instead of a hole. And in order to correctly and efficiently drill a hole in wood you need to listen to the advice of woodworkers, also called wood modelers.

How to drill with a drill properly and smoothly

In the field of repair, the ability to drill correctly is one of the basic.

In addition to general rules, it is important to consider all the nuances when working with a particular material: concrete, tile, metal, etc.д.

All issues related to drilling will be covered in this article.

As already mentioned, drilling is the most common occupation for the repairman, and therefore it is important to learn a few basic rules related to this activity right away.

  • Using the right tools. There are many drills, each of which is designed for a particular kind of material. Therefore, you should not try to drill concrete with a drill bit for wood and vice versa. It is also important to consider the conditions in which the tool will be used. For example, for repairs in the interior, you can not use an industrial drill (it’s simply not safe). The water resistance is important: outdoor work requires IP34 if the climate is humid, and IP32 if the work is to be done in good weather. Inside the room it is possible to use IPX2/
  • Good marking. Before you begin any work, it is important to accurately and precisely mark out the places of drilling with a marker. You can also put paper tape under the marker to prevent the drill from sliding on the material.
  • Choice of drilling speed required. Here it depends equally on the material and the diameter of the blade. When it comes to very fine drills (less than 3 mm in diameter), you have to work at low speeds, less than four hundred per minute. For other drill bits the rule is: the thinner the bit, the faster the drilling speed is needed.

It is also important to make sure that the hand lever is firmly attached to the hand drill shaft. It is also not allowed to skew the drill.

How to drill metal properly

The first thing to start with is the selection of drills. They are characterized by a sharp edge, designed for easy penetration of the drill into the metal.

drill, strictly

Conventional metal drill bits are good for not too hard metals like copper or aluminum, but for something harder (for example, stainless steel) you should get products made of titanium carbide or chrome vanadium alloy.

Separately, we should talk about the optimal speeds. A common mistake of beginners is to use too many RPMs.

In fact, for hard metals, medium speeds are used: for example, brass with a thickness of a centimeter will be optimal to drill at a speed of 2000-2500 revolutions.

There are a few more points to cover. So:

  • If you want to drill a thin iron plate, it should be fixed between two pieces of wood. This is done so that the sheet metal is not torn off.
  • It is necessary to use lubricating oil from time to time, which ensures the cooling of the drill bit and facilitates the drilling process.
  • If you want to make a hole in a pipe, it must be firmly secured. In order to prevent the pipe from flattening under the influence of the drill, a piece of hardwood should be placed inside.

If you follow these simple rules, then even a beginner will be able to qualitatively perform drilling.

How to drill concrete walls

Drill a wall in everyday life is most often necessary, because without it it is impossible to hang a shelf, a cabinet, you can not install cornices.

Of course, it is better to use a peorator or an impact drill for this purpose. These tools are powerful enough to handle a hard material like concrete or brick.

However, if the thickness of the wall does not exceed 10-12 cm, you can get by with an ordinary drill.

But do not take the risk if you only have a low-powered tool. in contact with concrete, it can simply break. If the drill is chosen correctly, then the following tips will be useful:

  • Before you start work, make sure that there are no pipes or other utility systems in the drilling area.
  • Drills that are taken for such work should be made of hard metals or alloys. Diamond drills are the best option.
  • If in the course of drilling will come across too dense areas of concrete, they must be punched with a small hammer and a pin (puncher).

Although it is generally possible to drill through a concrete wall with a drill, it should still be done with care. Otherwise, the breakage can be quite serious. It is best to use specialized tools for this.

How to work with tiles using a drill

Often people who do not have extensive experience in the field of repair, afraid to drill such a fragile material as tile.

However, it may become a real necessity, because you need the same for something to fix a variety of cabinets and shelves in the kitchen, bathroom or toilet.

drill, strictly

Alas, in many respects, the condition of the tile after drilling determines not the master who takes up the drill, but the one who laid this tile.

A competent tiler arranges the tile so that no voids are formed between the tile and the wall. In this case, careful drilling in no way will not harm the tile. If there are “air s” between the wall and the tile, most likely the tile will crack.

In order to properly drill the tile, you must take a drill, masking tape, peorator (or a powerful drill with drill bits on concrete). Next, it will be necessary to perform the following actions:

  • The place of drilling is marked with a piece of masking tape and a marker. The tape is here to prevent the nail from sliding on the tile surface.
  • Drilling is carried out strictly perpendicular to the material. The number of revolutions should increase gradually: from the minimum possible to 150-200 revolutions per minute. This prevents damage to both the material and the tool.
  • It is important to make sure that the drill bit does not overheat. If the drills start to smoke, they need to cool down immediately.

When the holes are made, you can insert the dowels. This is done with a hammer.

Drilling in cast iron. how to do it properly

Cast iron is a rather hard material, so it is very, very difficult to drill it.

How to insert the drill bit into the chuck

Turn the adjusting ring counterclockwise by hand. The jaws inside the chuck are separated by a little bit more than the drill bit.

Insert the drill bit into the chuck as deep as possible. The diameter of the tool to be clamped is allowed to be 2. 13 mm.

Clamp the drill by turning the adjusting ring clockwise by hand.

Insert the drill key into the hole on the body of the chuck so that the teeth on the key and the chuck click into place.

Turn the spanner clockwise under slight pressure until it reaches the stop, so that the drill bit is firmly seated. The keyhole comes in 2. 3, we put in each in turn for an even clamping.

Unplug the plug from the socket before carrying out any maintenance work.

To prevent the wrench from being lost, they secure it to the drill wire with duct tape.

A quick-action cam chuck that can be screwed in without a wrench is used less frequently. Comes with one or two adjusting sleeves with notches against slipping. If there is only one core, the body of the drill is held at a fixed position. If there are two guide sleeves, the part that is fixed to the spindle remains stationary. The sliding part is turned by hand: when holding the drill clockwise, when removing it counterclockwise.

How to drill a concrete wall with an ordinary drill

In the life of every person comes a time when it is necessary to make repairs in the house or apartment. And then there is the question of redoing the space: transferring outlets, updating wiring and drilling other holes for the realization of the design project of the room.

In the process of the work a variety of tools and drills are used. Of course, customers always prefer the more powerful models. There is a wide variety of tools on the market with which to organize.

Drilling ?? holes with a drill with compliance ?? coaxiality (drill bit).

A simple version of adapting household items to drill coaxial or perpendicular holes

  • Make sure there are no pipes or other communication systems at the drilling site before you begin.
  • The drills that are taken for this work must be made of hard metals or alloys. The best option is a diamond drill bit.
  • If too dense areas of concrete are encountered during drilling, they should be pierced with a small hammer and pin.

Although a concrete wall drill using a drill bit is generally realistic, it is worth doing with caution. Otherwise, the breakdowns can be quite serious. It is better to use special tools for this.

Using the conductor

It is possible to drill a deep hole of a perpendicular sample using a special device. the conductor. And such activities are carried out not only on an even basis, but also on the rounded parts of workpieces, at angular points.

  • Core to make a marking for the drill.
  • Stencil made of plastic.
  • Guide bushings in an amount of 6 pieces, the diameter of which corresponds to 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm.


To drill a reinforced concrete surface, it is necessary to use specialized tools. in our version, you can not do without homemade tools.

Depending on your preference and the diameter of the hole, you can use a rotary drill, also known as a small-sized electric drill. What is the best way to drill a concrete wall in an apartment or panel house: an ordinary electric screwdriver with a drill bit, can you make a hole in a concrete wall with a torch without dust, and how. Can I drill with an electric screwdriver? The first option has less power, but has less weight not a convenient design. Peorator, accordingly, has more potential, weight not size.

Be careful! Since the use of construction tools is often disposable, it is more rational to rent them. Given the fact that their price is quite high, thus you will save a considerable amount of money.

In addition to the existing tool, you need to buy special drill bits, which allow you to work on the concrete surface. drills with pobedite tips are chosen for the power drill.

The peorator has its own weight characteristics of a set of percussion heads, which, for the most part, are sufficient. As an additional component for the peorator, drill bits with tips are also used.

To form holes with a diameter of thirty-five to one hundred and twenty millimeters you use core bits that have teeth made of carbide. using them you can drill holes for sockets, switches, and so on.д. If you decide on such a question, how can you drill concrete with an electric screwdriver, there are also tungsten-carbide-plated drill bits. However, you should keep in mind that they are only suitable for units with a capacity of two or more than 1kW.


Sooner or later, most people who live in homes with concrete walls, there is a need to hang a cabinet, lamp, shelf or picture. At this point there is an urgent question of how to drill a concrete wall. It is no secret that every home handyman at least once in his life has faced this problem, but not everyone knows how to solve it. Many people bravely torture themselves with a drill and their own strength, but, not achieving the desired result, give it all up until the next attempt to make a hole in the wall. But the drill eventually breaks, and the shelves still remain standing somewhere in the corner of the room or gather dust in the closet. But there are still options. you just need to know them and be able to use them.

What do professionals advise?

Holes in concrete have to be made quite often, especially in the process:

  • Finishing work;
  • installing furniture;
  • suspension of the air conditioner;
  • additional installation of electrical wiring;
  • installing plumbing.

Solve the problem of holes in a concrete wall can be done in two ways:

It is worth noting that ordinary drills to make a hole in a concrete wall will not work, so before you start, you need to buy drills with specially soldered plates of high-strength pobedite alloy, which perfectly cope with concrete and brick. But it is not recommended to use them for soft materials, because pobedite drill bits do not cut them, but crush them.

What will help the home handyman?

In domestic conditions, when you need to make 2-3 holes in the concrete, you can get by with an ordinary drill, without the percussion function. To do this, it is necessary as the pobeditovogo drill into the body of the wall from time to time to break the concrete with a strong metal pin (puncher), which is the same size as the diameter of the hole. It is used when the drill starts to “stop” in the wall. At this point a steel puncher is inserted into the hole and begins to beat on it with a hammer or sledgehammer, trying to break up too dense areas and pierce the hole deeper. In doing so, the pin is rotated slightly. Then the hammerless drill can do the job again.

All of the above actions are repeated one after another until the hole increases to the desired depth. This method is quite time consuming and tedious, but for a couple of holes is quite acceptable.

Alternatively, you can use diamond-coated universal drill bits when drilling into the concrete. They are highly effective when working with metal, gravel, and concrete. They can only be installed on a regular power drill, or on a tool with the vibration function disabled.

The drill must be handled with extreme care or it will fail too quickly. Advice given by professionals. to avoid overheating the drill bit, it should be wet with cold water from time to time.

How to decide on a tool?

For more work, you need a peorator or drill, which has a percussion function, and drills with pobeditovye tips. Impact drill combines rotational with reciprocating motion, which helps it perfectly copes with lightweight concrete, and the question of how to drill a concrete wall, which is a carrier, there is a simple answer. the best helper will be a peorator, whose main purpose is the piercing of concrete fences. There is another difference:

Drill a rebar caught in the body of the concrete wall should be drilled with metal drills.

What drills large holes?

Professionals, constantly faced with the problem of drilling holes in concrete, use special equipment, which includes:

  • Powerful electric motor;
  • drilling motor;
  • diamond drill bits of different diameters;
  • diamond drill bit core drill rig secured to the base.

How To Drill A Straight Hole Without A Drill Press

diamond drill bits of different diameters can be drilled with large diameters. up to 40 cm. the process is quick, efficient, dust-free and quiet. Water is automatically applied to the drilling site, which simultaneously cools the diamond core and cleans the dust.

With diamond drilling holes are obtained precise in shape and clear in outline, with a polished inner surface. They can be made in various enclosing structures at any angle to the horizon, and the possibility of cracks or chips in the concrete is completely excluded. Destruction occurs only at the location of the future hole.

Specialized companies do diamond drilling, so if you need to drill holes in the concrete of large diameters, you can invite masters with their equipment. And you don’t have to buy a diamond drill rig specifically for this.
