Various Drill Bits For Cordless Tools

Drill bits are an integral part of any drill machine which is used to bore cylindrical holes in different materials like metal, wood, plastics, etc. The choice of a drill bit depends on your requirement. If you are looking at a few quick handy tools a set of steel twisted bits and a few masonry bits would be sufficient but if you are working on the floor then you would require bits which are larger and or designed for a specific purpose/material.

There are many types of drill bits designed for a specific purpose. For example the steel twist bits. The twist bits are useful while drilling metal sheets and can be used for wood, plastic and similar material. Most of the twist steel bits are made up of either High Speed Steel or Carbon Steel.

Both drill bits serve a different purpose like the carbon steel drill bit is used for drilling wood and not metal. The steel twisted bits are also available coated with Titanium Nitride (TiN). These drill bits display a typical gold like color. This coating gives the drill bit more hardness and also a self lubricating property.

This bit should only be used for drilling metal and not any other material. Special care should be taken when using the smallest sizes since these bits are thin and brittle. Always hold the drill square to the work and apply only light pressure when drilling.

Sharpening the blades or drilling areas regularly keeps the bits in shape and hence is cost effective. You can use a drill sharpener, a grindstone jig or an oilstone to do this job. Moreover sharpening the twist drill bits the Titanium Nitride coating can be destroyed. By forming a correct angle at the tip while drilling you can extend the life of the of your drill bit.
