Drill bits are cutting tools used to create cylindrical holes, almost always of circular cross-section. Bits are held in a tool called a drill, which rotates them and provides torque and
Axial force to create the hole. Specialized bits are also available for non-cylindrical-shaped holes.
Different surface treatment of HSS twist drill bits
Black Oxide---is an inexpensive black coating. A black oxide coating provides heat resistance and lubricity, as well as corrosion resistance. Coating increases the life of HSS bits.
Titanium Nitride (TIN) --is a very hard ceramic material that can be used to coat a high speed steel bit (usually a twist bit), extending the cutting life by three or more time. However, when the bit is sharpened the new edge, will not have the benefits of the coating.
Cobalt drill bits---are specially designed for drilling in hard steel, thick web helix delivers fast material removal combined with increased durability for maximum
