HMT Versadrive Impact Wrench Clutched Adapter Set – 3 Adapters + 5/16 - 1" Spiral Flute Taps

The VersaDrive® clutched tapping system is a unique method of effectively threading blind holes without risking damage to your taps.
Fit the adapter to a high-torque Impact Wrench, insert a VersaDrive® Spiral Flute ImpactaTap and start tapping. When the tap makes contact with the bottom of the hole, the clutch will engage and prevent the tap from breaking.
Then safely back out your tap for a perfectly tapped blind hole.
