Straight-Shank Auto-Reversing Tapping Heads

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.
Collets (sold separately) are required to connect your tap to these tapping heads.

Jacobs Taper Auto-Reversing Tapping Heads

Cut internal threads without stopping your machine—these tapping heads reverse nearly 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 built-in ball clutch lets you set the torque for your tap size and workpiece material, keeping threads clean and preventing tap breakage. Mount them to a Jacobs taper arbor on manual mills and drill presses. 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.
Collets (sold separately) are required to connect Tapmatic tapping heads to your tap.

Stop Bars for Auto-Reversing Tapping Heads
For clean, consistent threads as your tap backs out of a hole, these bars brace your tapping head's stop arm so it can't spin freely. Mount them to your machine’s quill or to a T-slot table. Keep in mind, your setup should be strong enough to handle your tapping head's maximum rated torque.
Quill mount bars clamp tightly around your spindle sleeve or quill.
T-slot mount bars use your machine table's slots as a rigid base. If the included nut doesn’t fit the slots in your table, choose from our other T-slot nuts.

Collets for Auto-Reversing Tapping Heads
Secure taps in auto-reversing tapping heads with these collets. They hold inch and metric taps with shanks that meet ANSI standards.
Collets for Tapmatic and for McMaster-Carr approved tapping heads are made of rubber that compresses to hold a range of tap sizes. Steel jaw inserts add strength and maintain grip as these collets squeeze the tap shank.
Collets for Procunier tapping heads fit a single shank diameter.
