Collis Tool 72423 Split Sleeve Tapping Driver MT2

Product Description

The COLLIS TOOL 72423 is a split sleeve tapping driver designed for use with a 3/8 inch tap on MT2 taper shank machine setups. It accepts taps with a shank diameter of 0.381 inches and a shank square of 0.286 inches, providing a secure, positive drive during tapping operations. The MT2 taper shank mounts directly into compatible drill press or milling machine spindles. A 1/4 inch projection positions the tap at the correct working distance, and the 1-3/64 inch tap entry depth suits standard threading tasks in metal fabrication and machining environments. Machinists and tool-and-die technicians are the primary users of this driver.

This tapping driver is suited for machine tapping operations on drill presses, milling machines, and similar equipment where an MT2 taper spindle is present. It is used in job shops, maintenance facilities, and production machining environments that require reliable tap drive and release in ferrous and non-ferrous materials. The split sleeve design allows for controlled tap engagement and helps protect taps from breakage during through-hole and blind-hole threading operations.

Installation Notes

Installation is performed by a machinist or qualified toolroom technician. Power down and de-energize the machine spindle completely before mounting or removing the taper shank driver. Clean the MT2 taper bore and shank with a lint-free cloth before seating to ensure full contact and prevent fretting. Never use the driver to hand-tap or apply side loads, as the taper shank is designed for axial machine tapping only.
