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.
