Collis Tool 72422 Split Sleeve Tapping Driver MT2

Product Description

The COLLIS TOOL 72422 is a split sleeve tapping driver designed for use with a 3/8 inch tap on Morse Taper 2 (MT2) spindles. It accepts taps with a shank diameter of 0.275 inches and a shank square of 0.206 inches, providing a secure, torque-transmitting grip during threading operations. The driver features a 1/4 inch projection and a tap entry depth of 1-3/64 inches, making it well-suited for controlled tapping in drill press and milling machine setups. Machinists and toolroom technicians working in job shops, production facilities, and maintenance environments will find this driver a dependable solution for accurate thread cutting.

This tapping driver is used in drilling and milling applications where a Morse Taper 2 spindle is present. It is appropriate for light-duty to medium-duty tapping work on drill presses, knee mills, and similar machine tools. The split sleeve design allows quick tap changes without fully disassembling the driver, improving workflow efficiency in both production and maintenance settings. It is suited for shops running ferrous and non-ferrous materials where consistent tap alignment and positive drive are required.
