Drill bits: standard set
The purpose of the drill is to drill holes, and for this, one must always have one of the most common attachments - a drill. Depending on the material to be worked on, you can use hardened steel drills, winning, diamond, the first are almost universal and are used for perforating metal, wood, gypsum board.
The shape of the drill bit can be different, so for holes with a diameter of 2 to 5 centimeters it is best to use feather drills( the name is the one they got because of the corresponding contour).
When working with soft materials, do not strongly press the drill, especially when it comes to drywall - you can eventually get chipped and cracking the edges of the hole.
When it is necessary to cut large holes in the sawn timber, nothing will help in the accomplishment of this task, as special bits - crowns. They are cylindrical drills with serrated edges, that is, they really resemble crowns, whose base is not the head of the monarchs, but the discs with the rods centered, by means of which the attachments are fixed in the clips of the drill chuck.
Additional features of the
Drill With which one often has to face during the finishing works - this is the perforation of concrete and the screwing of screws. With both, you will be able to cope with a drill, which must have a perforator mode. Screwdriver This tool can be replaced by switching the special lever to the "only drill" position with the setting of the minimum number of revolutions per minute.
Almost all the latest models of drills have a reverse, which allows you to twist and twist the screws at low revs. When working with concrete surfaces, the perforability is an indispensable tool, since the rotation of the special drill along with simultaneous translational movements gives the result not worse than from the work of a conventional perforator.
True, the diameter of the holes from the drill turns out slightly smaller, there is a certain limit. Nozzles for perforating are used the same, for concrete, already mentioned above. Their triangular tips are ideal for drilling hard materials.
And a few more functions for the
drill. Mixing plaster or other liquid mortar is a tedious task, but with the help of a special nozzle the drill can turn into a mixer, the main thing is that it is long enough and the spray does not get on the tool body. By the way, you can whip the usual dough with a drill, putting it at minimum speed.
Working with a drill as a mixer, do not forget that the main rule of this household appliance applies to it - remove the nozzle from the mixture only after the rotation of the cartridge has stopped completely. Less commonly used attachments are a kind of adapter that turns the drill into completely different tools. So, there is a nozzle, which, being installed on the cartridge, will work as an electric jigsaw.
There are flexible drills on a strong cable, they can be used in hard-to-reach places. On sale it is possible to find a nozzle-adapter, which turns a drill into a bulgarian, more precisely, it is an angular cartridge, which allows to install the nozzles at right angles to their usual position. For cleaning and polishing surfaces, grinding attachments, abrasive and made in the form of a rigid metal brush are very convenient.
