Collis Tool 71150 MT1 Morse Taper Drill Driver

Product Description

The COLLIS TOOL 71150 is an MT1 outside Morse taper drill driver designed to connect straight-shank or tang-style drill bits to Morse taper spindles in drill presses, lathes, and milling machines. It accommodates a drill size of 0.1285 inches decimal and provides a drill depth of 0.75 inches. With a 3/16 inch projection and compatibility with drill tangs ranging from 0.09 to 3/32 inches in thickness, this driver ensures a secure, concentric fit between the cutting tool and the machine spindle. Machinists, toolroom technicians, and maintenance professionals use this type of adapter to maintain precise alignment during drilling operations.

The 71150 is suited for use in machine shop and industrial maintenance environments where MT1 taper spindles are standard. It is typically installed in benchtop or floor-standing drill presses, engine lathes with tailstock Morse taper bores, and similar machine tools requiring a #30 drill driver interface. Applications include production drilling, toolroom work, and general metalworking where accurate drill seating and positive tang engagement are required.

Key Features

• MT1 outside Morse taper shank for direct spindle mounting
• Accepts drill tang thickness from 0.09 to 3/32 inches
• 3/16 inch projection length for proper tool engagement
• 0.1285 inch decimal drill size for precise bit compatibility
• 0.75 inch drill depth for secure chuck and bit retention
• Tang-compatible drive slot prevents bit rotation under load

Compatibility

Designed as an OEM-style replacement or direct-fit driver for machine tool spindles with an MT1 Morse taper bore requiring a #30 drill driver. Compatible with drill bits that include a tang drive feature within the specified thickness range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before installing or removing any Morse taper tooling. Clean the taper bore and the driver shank thoroughly before seating to ensure full metal-to-metal contact and concentricity. Never use a hammer directly on the driver body to seat or remove it; use a proper drift and a soft mallet on the drift only.
