Collis Tool 72420 Split Sleeve Tapping Driver MT2

Product Description

The COLLIS TOOL 72420 is a split sleeve tapping driver with an MT2 taper shank, designed for use with 1/4 inch taps in machine tool setups. The driver accepts a tap with a 0.255 inch shank diameter and a 0.191 inch tap shank square, providing a secure, torque-transmitting fit. The tap entry depth measures 31/32 inches, and the projection is 1/4 inch. This type of tooling is typically installed by machinists and tool and die professionals working on drill presses, milling machines, or tapping stations where repeatable thread depth and axial float are required.

Split sleeve tapping drivers are used in production and maintenance machining environments where tapping accuracy and tap protection are critical. The MT2 taper shank mounts directly into compatible spindles or arbors on drill presses and vertical milling machines. This driver is suited for ferrous and non-ferrous materials where controlled torque and axial compliance reduce tap breakage risk. It is appropriate for light-duty to medium-duty tapping operations in both job shop and production floor settings.

Key Features

Compatibility

Designed for use with 1/4 inch taps featuring a 0.255 inch shank diameter and a 0.191 inch tap shank square. Mounts in machine spindles or arbors with an MT2 Morse taper socket.

Installation Notes

Installation is performed by qualified machinists. Before mounting, ensure the machine spindle is fully stopped and the power source is locked out following OSHA lockout/tagout procedures. Clean the MT2 taper and spindle socket thoroughly before seating to ensure full contact and prevent fretting. Do not exceed the tap size rating for this driver, and verify tap shank dimensions match the driver specifications before use.
