Collis Tool 71205 Drill Driver 9/32 Inch MT1 Morse Taper

Product Description

The COLLIS TOOL 71205 is a drill driver designed to drive 9/32 inch twist drills with an MT1 outside Morse taper shank. It provides a 3/16 inch projection and accepts drill tang thicknesses from 0.158 to 0.162 inches, ensuring a secure mechanical fit between the drill and the taper socket. The 71205 is used in drill press, lathe, and milling machine setups where a Morse taper spindle must interface directly with a straight-shank or tang-drive drill. Machinists and tool-room professionals rely on this type of driver to maintain concentricity and transmit torque without slippage during drilling operations.

This drill driver is suited for metal fabrication shops, machine shops, and toolroom environments where MT1 taper sockets are standard. It is a direct-fit solution for machines equipped with MT1 spindle bores, including bench drill presses, lathes, and milling machines operating on smaller tooling sizes. The 0.2813 inch decimal drill size and 1 inch drill depth rating make it appropriate for precision drilling tasks requiring controlled depth and consistent alignment. Installation is performed by machinists or tool-room technicians as part of standard tooling setup.

Key Features

• MT1 outside Morse taper shank for direct mounting in MT1-bored spindles
• Accepts 9/32 inch (0.2813 inch decimal) twist drills
• Drill tang compatible, with accepted tang thickness range of 0.158 to 0.162 inches
• 3/16 inch projection provides precise drill positioning
• 1 inch drill depth rating for controlled-depth drilling applications

Compatibility

Designed as an OEM-style replacement driver for MT1 taper spindle machines accepting 9/32 inch drill tooling with tang-drive compatibility.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the driver from the taper bore. Clean both the taper shank and the spindle socket thoroughly before insertion to ensure full contact and prevent fretting. Do not force the driver using impact tools, as this can damage the taper seat or spindle bore.
