How to drill to drill a hole at a right angle? 4 Testing method

Greetings to all subscribers and visitors to the channel "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 the means at hand. It is quite a hot topic, because the drilling machine or other special devices that are easy to cope with this task, there is not in every home workshop, and drilling on the eyes, trying to keep the right angle, almost really. Today you will learn 4 method, such as drilling at a right angle, with whom I spent own experiment and at the end of the article you can see Video with the results of their testing.

1. Metal corner

The most common and easiest way to drill a hole at a right angle, is to use a metal corner. Tightly putting a corner to a drill bit so that it is in contact with the drill with two sides and the drill hole. The result is very good, almost without errors. In addition to metal corner fit and wood, which can be easily glued from the two bars. The only drawback of this method is that not to turn a drill to drill a hole of a small diameter, because of the height of the corner, the drill will abut it.

2. Mirror

Make a hole at right angle drill of any diameter, it is possible using the conventional mirror. To do this, you need to make a drill lined up with its mirror image in one straight line.

The slightest deviation will be noticeable, but having tested this method I found that an angle of 90 degrees will turn on only one side, the other will be a noticeable error. Increase the accuracy of the angle possible, to use two mirrors.

3. Two mirrors with notches

A more accurate result is obtained by using two mirrors with notches, which are fixed on a wooden corner.

The essence of this method lies in the fact that due to specular reflections of the drill, guided by the lines, can exhibit a 90 degree angle from the two axes. But this method also has disadvantages. Firstly, with two mirrors design rather cumbersome, and secondly, to drill a hole is not very convenient, because you need to look from the side and at the same time to focus on the two sides. Read more about the test results of this method, see my video.

4. Nut

And the final way to drill a hole at an angle of 90 degrees, is to use the union nut (or two nuts crocked tape). The result is almost ideal, such as when using a furniture conductor. However, there is one "but." This method is suitable if you use a non-standard diameter drill. For example, to drill a hole to the M8 nut can only drill diameter of 7 mm. To use a drill bit with a diameter of 8 mm drill must first thread of the nut.

Output

In principle, all these methods work and what exactly are vospolzovatsya you decide. If we evaluate the accuracy of the angle, I really liked the area and the metal nut.
