Procunier Auto-Reversing Tap Holders
for Straight and Morse Taper Spindles

These instantly reversing tap holders allow you to back out of a hole once it has been tapped without stopping the machine's motor. They’re also known as tapping heads. Use them for fast, precise tapping on manually operated drill presses and milling machines. Collets (sold separately) are required to connect the tap to the holder.

Auto-Reversing Tap Holders for Jacobs Taper Shanks

Also known as tapping heads, these holders instantly reverse, allowing you to back out of a hole once it has been tapped without stopping the machine's motor. Use them for fast, precise tapping on manually operated drill presses and milling machines. Each holder comes with a chart that indicates the maximum speed, which may be lower depending on the tap size and workpiece material. Collets (sold separately) are required to connect the tap to the holder.

Air-Powered Tap Wrenches

Powered by compressed air, these tap wrenches thread holes faster and with less effort than manual tap wrenches. They’re often used in place of manual tap wrenches when threading many holes and hard materials. Compared to drill presses and CNC machines, which are stationary, these wrenches are portable so you can take them to the part that needs to be threaded. To remove chips from your hole, press the reverse button to rotate the tap counterclockwise. Switch different taps in and out of the chuck when your tap is worn down or you need a new size. Use with machine tool taps and tapping lubricants for best results.
