Product Description

Production Description
Shank: The shank is the portion of the drill bit that fits into the chuck of a drill. It is typically cylindrical and has a specific size and shape to match the chuck of the drill. The shank allows the bit to be securely held in place while rotating.

Body: The body of the drill bit is the main part that contains the cutting edges and determines the size and type of hole it can create. The body is usually made of hardened steel or other durable materials to withstand the forces generated during drilling.
