About Spiral Point Machine Taps

Suitable for tapping holes that go all the way through a workpiece, spiral-point machine taps have a spiral point that pushes chips in front of the tap as it moves into the material and out through the other side, eventually pushing the chips out of the hole. These taps are intended for use on a drill press, lathe, or CNC machine.
