Collis Tool 72308 Drill Driver MT2 23/64 Inch

Product Description

The COLLIS TOOL 72308 is a Morse Taper drill driver designed to connect straight-shank tooling to MT2 spindles in a wide range of drilling applications. The driver features an MT2 outside taper shank with a 1/4-inch projection and accepts drill tangs measuring 0.199 to 0.203 inches in thickness, ensuring a secure mechanical connection between the driver and the drill bit. The 23/64-inch (0.3594 inch decimal) drill size supports precision hole-making operations in machine shop, maintenance, and production environments. This type of tooling is installed and serviced by machinists, toolroom technicians, and maintenance mechanics working with drill presses, lathes, or milling machines equipped with MT2 spindle sockets.

The 72308 is suited for use in machine tools that accept MT2 taper tooling. With a drill depth capacity of 1-1/8 inches and a compatible drill tang interface, it is appropriate for standard drilling operations in ferrous and non-ferrous materials. The driver is used in both production and job-shop settings where repeatable, positive-locking taper connections are required to maintain drill alignment and prevent tool pullout under load.

Compatibility

Designed for use with MT2 spindle sockets on drill presses, lathes, and milling machines that accept standard Morse Taper No. 2 tooling and drills with a compatible tang thickness of 0.199 to 0.203 inches.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Before installing or removing the driver, ensure the machine spindle is fully stopped and locked out per applicable lockout/tagout procedures. Clean the taper bore and driver shank thoroughly before seating to ensure full contact and prevent fretting. Use a proper drift key and drift slot to remove the driver from the spindle - never strike the tooling directly with a hammer.
