Not every home craftsman has a drilling machine that will allow you to make a hole at a perfect right angle. And it’s almost impossible to drill like this with a conventional electric drill or screwdriver - the error will still be noticeable. And yet, there are several effective methods that can be used to achieve perpendicular penetration of the drill into the material.
Using a metal corner
The most popular and simplest method of drilling at right angles is to use a metal corner. To do this, you need to place a corner at the drilling site so that the fold is located exactly in the location of the future hole. Next, a drill fixed in a drill or screwdriver is applied to the inner fold of the lotion along its entire length. You need to drill slowly, avoiding deviation from the corner.
This method is very good. Holes are obtained with minimal error. The only downside is that the height of the angle limits the use of the drills used. For example, for a small diameter hole, drill bits are usually short. But when using such a lotion, the tool cartridge will rest against it and not allow it to move further into the depth of the material.
Completion of equipment manufacturing work
- The manufactured product is painted;
- Lubricate all units that move;
- If necessary, a socket is installed on the base to connect the drill being used to the electrical network.
Using this scheme, you can assemble not only vertical, but also horizontal machines for drilling holes.
With a regular mirror
The mirror method is suitable for any drill. It should only be placed on the material being processed with the reflective part up, and when the drill rests, achieve a perfectly straight line between the reflection and the cutting attachment itself. If there is a deviation during operation, the line at the convergence point will bend.
The method is really very good. The only drawback is that a perfectly even angle is obtained from only one plane. This can be changed by using two mirrors.
There is a combined way to use a corner and mirrors. Mirrors are attached to the two inner walls of the corner, and lines are drawn at an equal distance from the convergence point. This method can be considered the best among the others, since the accuracy of the work done will be very high.
How to drill a hole at a right angle with a drill? Testing 4 methods
Greetings to all subscribers and guests of the Podelkin
!
In this article we will talk about how to drill a hole at a right angle (90 degrees) with a drill or screwdriver using available tools. This is quite a relevant topic, because not every home workshop has a drilling machine or other special devices that can easily cope with this task, and drilling by eye, trying to maintain a right angle, is practically impossible. Today you will learn 4 ways to drill at right angles,
with which I conducted my own experiment and at the end of the article you can watch
a video with the results of their testing.
Metal corner
The most common and easiest way to drill a hole at a right angle is to use a metal corner. We firmly place the corner on the drill so that it comes into contact with the drill on both sides at once and drill a hole. The result is very good, almost without errors. In addition to a metal corner, a wooden one is also suitable, which can be easily glued together from two bars. The only drawback of this method is that it will not be possible to drill a hole with a small-diameter drill, since due to the height of the corner, the drill will rest against it.
Mirror
You can make a hole at right angles with a drill of any diameter using an ordinary mirror. To do this, you need to make sure that the drill lines up with its mirror image in one straight line.
The slightest deviations will be noticeable, but after testing this method, I was convinced that an angle of 90 degrees would be obtained only on one side, on the other there would be a noticeable error. You can increase the accuracy of the angle if you use 2 mirrors.
Two mirrors with notches
A more accurate result is obtained if you use two mirrors with notches, which are fixed on a wooden corner.
The essence of this method is that thanks to the mirror reflections of the drill, guided by the lines, you can set an angle of 90 degrees along two axes at once. But this method also has disadvantages. Firstly, the design with two mirrors is quite cumbersome, and secondly, drilling a hole is not very convenient, since you need to look from the side and simultaneously navigate on both sides. For more information about the testing results of this method, see my video.
screw
The last way to drill a hole at a 90 degree angle is to use a union nut (or two nuts wrapped with electrical tape). The result is almost perfect, the same as when using a furniture jig. However, there is one “But”. This method is suitable if you use a drill of non-standard diameter. For example, you can only drill a hole with an M8 nut with a drill with a diameter of 7 mm. To use a drill with a diameter of 8 mm, you will first have to drill the threads of the nut itself.
Conclusion
In principle, all of these methods are working, and it’s up to you to decide which one you use. If we evaluate the accuracy of the angle, I liked the metal corner and nut the most.

With connecting nut
Precise drilling results can be achieved by using a coupling nut or several regular nuts wrapped with electrical tape. The process of use is very simple: the lotion is placed on the surface of the material being processed and held firmly by hand; Next you need to insert the drill into the hole and start working.
The accuracy of the result is amazing, but there is also a drawback. Unfortunately, with such gadgets it is possible to drill perpendicularly only rarely used diameters: with an M5 nut, you will have to use a 4 mm cutting attachment, and with an M10 - 9 mm. You can get out of this situation by drilling out the threads of the nuts, then the holes will have more common diameters.
All three methods are good in their own way. It all depends on the required angle accuracy, as well as the characteristics of the diameter used. In any case, it is not necessary to purchase an expensive drilling machine for one-time use. It is quite possible to make do with the means at hand that will allow you to get an impressive result.

Drill stand DIOLD SMS-43
The device consists of three main units - a base, a column and a traverse for attaching an electric drill. The base and traverse are made of silumin. The table surface and legs are sanded in one setting, meaning they are parallel, which ensures perpendicularity when drilling. The base has milled grooves for attaching a vice. Column height - 50 cm, diameter - 25 mm. The diameter of the hole for the drill is 43 mm. There is a locking ring to limit the drilling depth. Factory-made drill guides combine:
- type of construction;
- aesthetic appearance;
- assembly inaccuracy;
- different suppliers;
- one manufacturer is China.
