Collis Tool 72425 Split Sleeve Tapping Driver MT2

Product Description

The COLLIS TOOL 72425 is a split sleeve tapping driver designed for use with a 1/2 inch tap and an MT2 (Morse Taper 2) taper shank. It provides a positive drive connection between the machine spindle and the tap, allowing the tap to float axially and release when the cut is complete. The driver accepts a tap shank diameter of 0.367 inches and a tap shank square of 0.275 inches. Tap entry depth is 1-3/32 inches with a 1/4 inch projection. Machinists and tool and die technicians install this driver in drill presses, milling machines, and tapping machines where controlled thread-cutting operations are required.

This tapping driver is suited for production and maintenance machine shops performing internal thread operations on ferrous and non-ferrous materials. The MT2 shank fits directly into any machine spindle or tailstock with a matching Morse Taper 2 socket, making it a common choice for bench drill presses and manual mill setups. It is appropriate for through-hole and blind-hole tapping applications where tap float compensation is needed to prevent tap breakage.
