Collis Tool 72320 Drill Driver MT2 Morse Taper 29/64

Product Description

The COLLIS TOOL 72320 is a drill driver designed to secure and drive 29/64-inch twist drills using an MT2 outside Morse taper shank. The driver provides a 1/4-inch projection and accepts drill tangs between 0.239 and 0.243 inches thick, ensuring a firm mechanical connection between the drill and the spindle. This tool is used in drilling operations where a Morse taper spindle is the standard interface. Machinists, toolroom technicians, and maintenance professionals install this driver on drill presses, lathes, and milling machines equipped with MT2 taper bores.

The 72320 is suited for production and job-shop environments where 29/64-inch drills are run on MT2 taper machines. With a drill depth capacity of 1-1/4 inches and a decimal drill size of 0.4531 inches, this driver handles standard through-hole and blind-hole drilling tasks. It is appropriate for use in both manual and CNC-style spindle setups that accept MT2 tooling.

Key Features

• MT2 outside Morse taper shank for direct spindle mounting on MT2-equipped machines
• Accepts 29/64-inch drills with a decimal size of 0.4531 inches
• 1/4-inch projection positions the drill accurately relative to the spindle face
• Drill tang compatibility confirmed - accepts tangs from 0.239 to 0.243 inches thick
• 1-1/4-inch drill depth capacity for standard drilling applications

Compatibility

Designed as an OEM-style drill driver for MT2 taper spindles accepting 29/64-inch drill shanks with standard tang dimensions.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before mounting, power down and lock out the machine spindle fully. Clean both the MT2 taper bore and the driver shank with a lint-free cloth to remove oil and debris - any contamination will prevent full taper seating and can cause the driver to pull loose under load. Verify tang thickness is within the 0.239 to 0.243-inch range before insertion.
