What Are Drill Bits?

Drill bits are the tips put at the chuck of the drill. These bits are detachable and replicable with other bits. Drill bits are used to make holes or drive fasteners into materials. The cutting drill bits remove materials and make holes of various types. They come in various shapes and sizes according to the material they will be used for and the kind of hole they will be used to create.
