Quickly cut internal threads without stopping your drill press or manual mill. These tapping heads reverse twice as fast as they cut, so you can move to your next hole faster. When you lift the quill, they automatically back the tap out, which also helps reduce wear on your machine and taps. A cone clutch system with a tactile stop lets you feel when the tap reaches the bottom of the hole, preventing your taps from breaking in blind holes. These tapping heads are set up for right-hand tapping but can be reconfigured for left-hand tapping. Mount them on machines with a straight spindle or use a collet chuck, drill chuck, or other holder to fit any machine. Add a stop bar to your setup if you can’t brace the stop arm on your machine.

Choose your tapping head based on your tap size and maximum speed. For small holes and soft material, select a head that runs at higher speeds. For large holes and hard material, select a head with a larger tap size since they generate greater torque.
