Drill bits are made from different grades of raw steel which are delivered to manufacturing plants. The steel goes through a process of cutting and heat treatment at extremely high temperatures, to harden the steel. The bits are then cleaned, tempered, grounded, fluted and pointed. Specialist drill bits go through additional processes such as split pointing.

Drill bits are used to drill small to large holes in stone, granite, marble, concrete, brick, plaster, plastic, steel, wood, composites, ceramic tiles, glass and much more.
