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.
