The purpose of this tool - drilling holes in wood and metal.Electric drill consists of an electric motor connected to the spindle chuck for drill through the serial chain fastenings.See how to choose the drill to home properly.In most cases the twist drills are used for drilling.Deep into the material the drill must penetrate gradually, without jerks and jolts.If necessary, perform a through-hole pressure must be reduced as we move the drill.

In the bottom of the drills is a longitudinal trough with ostrorezhuschim edge and pulling for a bit, giving it Centering direction, screw tip.In operation, the chips are not removed, thereby have to be periodically removed from the drill hole.This drill hole to perform accurate is rather difficult.When drilling, do not push on the drill is very strong, because the tree may crack.For this reason, drills are not only suitable for jobs requiring high precision, such as drilling holes for screws.

How to work with an electric

center drill, compared with lozhechnym, has the best performance.His cutting portion is a blade having a sharp end (center), lateral incisor (roadster) and located radially flat knife.The drill tip is centered.It operates as follows: the side cutter trimmed timber is removed as a flat spiral belt knife.If necessary, drill hardwood will require a lot of physical effort.

most convenient are spiral, helical, cylindrical drill.Zaglubitel screw having a conical shape facilitates the easy entry of the drill into the wood.Sharp cutters (roadster), cutting wood in a circle are lateral end of the helical ribbons.Undercut timber is removed by a knife, and a flat spiral rises.The diameter of the drilled holes define roadster.For finishing best suited with a shallow notch the tip of the drill.

Drills with a large incision needed for working with soft wood.Work twist drill much easier than all the others.In some cases, when drilling wood breaks off at the point of the drill exit, but the very hole turns oblique.To avoid such troubles, you should observe the following rules:

workpiece, which will be drilled must be securely fastened;

future centers of holes need to outline a pencil or awl;

precision drill direction you need to check twice: before the start of drilling when the drill enters a small depth;

when drilling a deep hole drill direction can be checked by eye, guided by the line, pre-drawn by pencil.

to drill a blind bore, use a limiter, which serves as a piece of wood.It is placed on the side of the drill and drill until the stop contacts the chuck.Before you get started, drill a larger diameter drilled bar to obtain a device for monitoring the drilling angle.It allowed the implementation of several holes at different angles, which will then be the benchmark.Next to each of them make the necessary notation for the universal template.

Often tree spalling observed at the site of the drill exit.To prevent this, you should closely monitor the output of the sting out.Just as soon as it may seem, it is necessary to turn the piece and finish drilling.Generally, drilling possible in one direction, but in this case a small block of wood to be treated placed under the bottom of the object.

Sometimes there is a need to expand the already drilled hole.To this end into the opening and placed wooden plug drill screw in its middle.In this case, the plug serves as a centering unit, guiding the drill holes on the lower axis.You can use a drill and as an auxiliary tool for gouging nests.This requires a drill with a diameter equal to the width of the future opening.At the desired depth is drilled a number of slots, and then the rest of jumpers removed chisel.

during storage to prevent damage to the drill head should be screwed on a sting or a wooden wine stopper suitable size.Do not forget - the safety of work in the first place!
