Collis Tool 72247 Drill Driver 5/32 Inch MT2 Morse Taper

Product Description

The COLLIS TOOL 72247 is a drill driver designed to adapt straight-shank twist drills into MT2 (Morse Taper No. 2) spindles and tailstocks. It accepts a 5/32 inch (0.1563 inch decimal) drill shank and provides a 1/4 inch projection with a drill depth of 3/4 inch. The driver features tang compatibility, allowing the drill to seat securely and transfer torque without slipping. This type of drill driver is a standard toolroom and machine shop accessory used by machinists and tool-room technicians to run small-diameter drills in drill presses, lathes, and milling machine setups equipped with MT2 tooling.

The 72247 is suited for metalworking applications where a 5/32 inch drill must be driven from an MT2 taper socket. Typical install scenarios include production drilling on a lathe tailstock, bench drill press work, and tool-room setups requiring precise small-diameter hole making. The driver accepts drill tang thicknesses ranging from 0.09 inch to 3/32 inch, giving it compatibility with a range of standard 5/32 inch twist drills that fall within that tang dimension window.

Key Features

• MT2 outside Morse taper shank for direct mounting in MT2-socket spindles and tailstocks
• Accepts 5/32 inch (0.1563 inch) drill shank diameter
• Drill depth of 3/4 inch for secure shank engagement
• 1/4 inch projection keeps the drill close to the socket face, reducing overhang
• Tang-compatible design locks the drill against rotational slip under torque
• Compatible drill tang thickness range: 0.09 inch to 3/32 inch

Compatibility

Designed for use with standard 5/32 inch straight-shank twist drills having a tang thickness between 0.09 inch and 3/32 inch, installed in machine tool spindles or tailstocks with an MT2 (Morse Taper No. 2) socket.

Installation Notes

Installation is performed by machinists or tool-room technicians. Power down and lock out the machine spindle before inserting or removing the driver. Clean the MT2 taper bore and the driver shank with a lint-free cloth to remove oil and debris before seating - contamination in the taper interface reduces holding force. Drive the taper home with a firm hand push or a soft mallet tap; never use a steel hammer directly on the driver body. Use a drift through the spindle knockout slot to remove the driver safely.
