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.
