Collis Tool 75112 MT5 Taper Shank Split Sleeve Tapping Driver

Product Description

The COLLIS TOOL 75112 is an MT5 taper shank split sleeve tapping driver designed for use with 1-1/4 inch pipe taps. It accepts taps with a shank diameter of 1.312 inches and a tap shank square of 0.984 inches. The split sleeve design secures the tap shank while allowing controlled axial float, which helps protect both the tap and the workpiece during threading operations. This driver is intended for use in machine tool spindles fitted with an MT5 taper socket. It is typically installed and used by machinists, pipefitters, and maintenance tradespeople performing pipe thread operations on lathes, drill presses, or tapping machines.

This tapping driver is suited for production and maintenance environments where 1-1/4 inch pipe threads must be cut with repeatable accuracy. The MT5 taper shank provides a secure, self-holding fit in compatible machine spindles. The 2-1/8 inch tap entry depth and 7/16 inch projection accommodate standard 1-1/4 inch pipe tap geometry. It is appropriate for use in metalworking shops, mechanical contractors, and industrial maintenance settings requiring precision pipe thread tapping.
