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.

Ensure that you do some research to understand the
specifications in a better way. Reading reviews on different bits is also
beneficial as it helps you to find out more about them. Such reviews provide you
with complete insight on various products available on the block and also detail
you with the pros and cons of them. You can very well find such reviews online
wherein customers also share their experience of the same.
