Auto-Reversing Tap Holders for Jacobs Taper Shanks
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. Each holder comes with a chart that indicates the maximum speed, which may be lower depending on the tap size and workpiece material.
