Collis Tool 73011 Drill Driver MT3 Morse Taper 31/64 in

Product Description

The COLLIS TOOL 73011 is a drill driver designed to adapt a 31/64-inch twist drill with a Morse Taper 3 (MT3) outside taper shank for use in compatible taper-socket spindles. It provides 1/4-inch projection and accepts drill tang thicknesses ranging from 19/64 to 0.303 inches, making it a precision adapter for securing drills in machine tool applications. The 73011 is intended for use by machinists, tool-and-die professionals, and maintenance technicians working with drill presses, lathes, or milling machines equipped with MT3 taper sockets. Drill depth capacity is 1-5/16 inches.

This drill driver is suited for metal fabrication shops, machine shops, and industrial maintenance environments where consistent, repeatable drill positioning is required. The MT3 outside taper interface is a common standard across a wide range of bench and floor-model drill presses as well as lathe tailstocks. The tang-compatible design locks the drill securely against rotational slip under load, which is critical for production drilling operations.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with Morse Taper tooling. Always power down and lock out the machine before inserting or removing the drill driver from the spindle socket. Use a proper drift key and soft mallet to seat the taper fully and to remove it safely. Do not force an improperly sized tang into the driver, as this can damage the taper socket.
