The HMT VersaDrive™ Clutched tap collet system is a unique method of effectively threading blind holes.
One collet works with the range of Patented VersaDrive™ taps. When the tap comes to the bottom of the hole, the clutch system will engage and stop the tap from breaking. The tap is then reversed out of the completed hole.
This system fits a 19.05mm (3/4") magnet drill arbor, or can be adapted for use with a 1/2" or 3/4" impact wrench.
