Collis Tool 73026 Drill Driver MT3 Morse Taper 23/32 in

Product Description

The COLLIS TOOL 73026 is a drill driver with an MT3 outside Morse taper shank, designed to hold and drive a 23/32 inch drill bit in compatible taper-bored spindles. The driver features a 1/4 inch projection and accepts drill tang thicknesses from 7/16 inch to 0.443 inch, providing a secure mechanical fit during drilling operations. With a drill depth capacity of 1-5/8 inches, this driver suits production drilling, maintenance machining, and toolroom work where accurate taper alignment and positive drive are required. Machinists and tool-and-die technicians install this component when mounting a drill shank to a machine spindle or arbor equipped with an MT3 taper socket.

This drill driver is intended for use in machine spindles, drill press quills, or lathe tailstocks fitted with an MT3 inside taper. It is suited for metalworking environments including job shops, manufacturing facilities, and maintenance departments where 23/32 inch twist drills with a compatible tang must be driven from a standard MT3 taper holder. The driver transfers rotational torque from the spindle to the drill bit through the tang slot interface, reducing slip under cutting load.

Key Features

• MT3 outside Morse taper shank for positive, self-locking fit in matching spindle sockets
• Accepts 23/32 inch drill size (0.7188 inch decimal equivalent)
• Drill tang compatible design with 7/16 inch to 0.443 inch tang thickness range
• 1/4 inch projection for proper drill seating and alignment
• 1-5/8 inch drill depth capacity suitable for standard production drilling

Compatibility

Designed for use with machine spindles and toolholders equipped with an MT3 inside Morse taper socket that accept a drill driver for 23/32 inch tang-drive drill bits.

Installation Notes

Installation is performed by qualified machinists or tool technicians. Power down and de-energize the machine spindle completely before inserting or removing any taper tooling. Clean both the taper shank and the spindle socket with a lint-free cloth to remove chips, oil, and debris before seating the taper, as contamination will prevent full contact and may cause runout. Use a proper drift key and drift slot to remove the driver from the spindle - never strike the drill or driver body directly to dislodge a seated taper.
