HMT Versadrive Morse Taper 3 Clutched Tapping Adapter – M30 132003-M30 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-power, reversible Morse Taper magnetic drill, 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.
