Collis Tool 71183 MT1 Morse Taper Drill Driver Size 5

Product Description

The COLLIS TOOL 71183 is an MT1 outside Morse taper drill driver designed to secure and drive taper-shank drill bits in machine tool spindles. Sized as a number 5 driver with a 3/16 inch projection, it accepts drill tangs ranging from 0.118 to 0.122 inches in thickness. The 71183 is compatible with drill bits featuring a drill tang and is intended for use in milling machines, drill presses, and lathes equipped with a No. 1 Morse taper spindle socket. Machinists and toolroom technicians rely on this style of driver for accurate, repeatable bit seating.

This drill driver is suited for light-duty machining operations where a No. 1 Morse taper interface is specified. The 7/8 inch drill depth and close tang tolerance window make it appropriate for smaller diameter tooling. Typical applications include production drilling, maintenance machining, and toolroom setups where consistent tang engagement and taper alignment are required. This size is commonly found in bench drill presses and compact milling spindles used in industrial and trade shop environments.

Compatibility

Designed as an OEM-style replacement or standard toolroom component for machine tool spindles with a No. 1 Morse taper socket that require a number 5 drill driver with tang compatibility.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before inserting or removing taper tooling. Clean both the spindle taper socket and the outside taper of the driver before seating to ensure full contact and prevent fretting. Use a proper drift key and mallet to seat and remove Morse taper tooling - do not use impact methods that could damage the spindle bore.
