Collis Tool 72424 Split Sleeve Tapping Driver MT2

Product Description

The COLLIS TOOL 72424 is a split sleeve tapping driver designed for use with a Morse Taper 2 (MT2) taper shank spindle. It accepts a 7/16 inch tap and provides a tap entry depth of 1-5/64 inches, making it suited for consistent and repeatable tapping operations on drill presses and milling machines. The driver uses a split sleeve mechanism to grip the tap shank and square, transmitting torque while allowing the tap to float axially for accurate thread cutting. The tap shank diameter is 0.323 inches and the tap shank square is 0.242 inches. Installation is handled by machinists and tool-room technicians working with MT2-equipped machines.

This tapping driver is used in machine shop environments where tapping operations are performed on a drill press, turret lathe, or vertical milling machine fitted with an MT2 spindle taper. It is appropriate for production and jobbing work requiring a reliable tap-holding solution. The 1/4 inch projection dimension positions the tap correctly relative to the sleeve for proper engagement. This driver accommodates the specified tap size and shank geometry and is not intended for hand tapping applications.

Installation Notes

Installation is performed by a qualified machinist or tool-room technician. Before mounting, ensure the machine spindle is fully powered down and at a complete stop. Clean the MT2 taper shank and spindle socket thoroughly before seating to ensure proper contact and prevent fretting. Do not use the driver beyond the specified tap size and shank geometry, as mismatched tooling can result in tap breakage or spindle damage.
