Air-Powered Tapping Arms
 |
Thread through holes faster than electric tapping arms. These arms run at 700 rpm to speed up repetitive tapping tasks, such as threading small holes in steel. They’re also simple to operate—just connect them to your air supply and pull the trigger.
These arms are faster than a tap wrench and easier to reposition than a drill press. They’re often used alongside CNC machines to handle small tapping jobs, keeping the CNC machine free for other work. You’ll also need tap collets (sold separately).
For Tap Size is based on tapping holes in steel.

Electric Tapping Arms
 |
Thread blind and through holes across a range of sizes for more versatility than air-powered arms. Use the touchscreen on these arms to set the torque and speed you need for your hole. You can also set an exact depth, which is particularly useful for tapping blind holes. When the depth is reached, the motor stops and reverses the tap out of the hole, so you don’t bottom out and break a tap. Plug these arms into any outlet and get tapping. They’re also quieter than air-powered arms.
These arms are faster than a tap wrench and easier to reposition than a drill press. They’re often used alongside CNC machines to handle small tapping jobs, keeping the CNC machine free for other work.
These tapping arms include a full set of tap collets. When the torque gets too high, the collets spin freely instead of forcing the tap to turn and break. They also unlock quickly, so you can swap taps in seconds.
For Tap Size is based on tapping holes in steel.
Horizontal Tapping—Tilt the head 90° to tap holes on the side of your workpiece without unclamping and repositioning it.
