Drill bits are hand tools used to create cylindrical holes. The technique is that bits are held in a tool called a drill, which rotates them and provides axial force to create the hole. Specialized bits are also available for non-cylindrical-shaped holes. There are different types of drill bits that come in different standard sizes. Twist drill bit is the type which is more useful. It drills holes in metal, plastic and wood. Indexable drill bits are used in high precision or production equipment. There are also spade drill, tile bit drill, ejector drill, wood drills, lip and spur drill.

The materials from which bits are made play a big role in the life and performance of the drill bits. There are steel bits, titanium coated bits, carbide-tipped bits, carbide-tipped bits and cobalt bits. Steel bits work well for boring in softwood. High speed steel bits are harder than steel bits and stay sharper longer. Titanium coated bits stay sharp longer than steel and high speed steel bits. Carbide-tipped bits stay sharp much longer than steel, high-speed steel or titanium bits. Cobalt bits are extremely hard and dissipate heat quickly. They are most commonly used for boring in stainless steel and other metals.
