Taps are used to cut a thread on the internal surface of a hole, creating the female component of an assembly, such as a nut or socket. We offer an extensive line of high-quality taps that includes the following types: extension, pulley, hand, pipe, spiral flute, spiral point, straight flute, screw thread insert, and thread forming taps.

A spiral point tap (or gun tap) is designed for tapping through holes. Its key feature is an angled cutting face that pushes chips forward and out of the hole. This allows for faster tapping, better thread quality, and reduced tap breakage compared to other taps in through-hole applications.
