What is a twist drill?
Date: 2023-05-13 10:02:21

A twist drill is a tool that cuts a circular hole of a workpiece by rotating it with respect to a fixed axis. It is named because its chip flute is spiral and shaped like a twist. The spiral groove has 2 slots, 3 slots or more slots, but 2 slots are most common. Twist drills can be clamped to manual, electric hand-held drilling tools or drill presses, milling machines, lathes and even machining centers. The bit material is generally high speed tool steel or cemented carbide.
