Collis Tool 73012 Drill Driver 1/2 Inch MT3 Morse Taper

Product Description

The COLLIS TOOL 73012 is a drill driver designed for use with 1/2 inch drill chucks and MT3 (Morse Taper 3) outside taper shanks. It provides a 1/4 inch projection and accepts drill tang thicknesses ranging from 19/64 inch to 0.303 inch, making it compatible with a range of straight-shank drills. The MT3 taper shank seats securely in matching spindle sockets, transmitting torque without slippage. This driver is a standard machine shop and metalworking accessory installed by machinists, toolroom technicians, and industrial maintenance professionals working with drill presses, milling machines, and lathes equipped with MT3 spindle sockets.

The 73012 suits applications where a 1/2 inch drill chuck must be mounted on an MT3 taper spindle. It is used in production machining, toolroom setups, and maintenance environments where drill press or lathe spindle tooling changes are routine. The 1-5/16 inch drill depth specification guides proper chuck and tooling setup, ensuring adequate engagement for reliable operation during drilling cycles.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before mounting or removing the driver, power down the machine and bring the spindle to a complete stop. Ensure the MT3 taper socket and shank are clean and free of chips or burrs before seating to prevent damage to the taper surfaces. Use a proper drift and mallet at the designated drift slot to remove the driver from the spindle - do not pry or strike the chuck body directly.
