Accupro HX01303000MSC Drill Chuck 3MT Taper Shank Keyed

Product Description

The ACCUPRO HX01303000MSC is a keyed drill chuck designed for use with 3MT (Morse Taper 3) taper shank spindles on drilling machines, lathes, and milling equipment. It accepts drill bits and round-shank tooling from 1/32 inch (0.0313 inch) up to 1/2 inch (0.5000 inch) in diameter. The chuck features a steel body with a plain bearing design and a 54 mm sleeve diameter. With a maximum spindle speed of 8,000 RPM and a TIR of 0.0012 inch, this chuck is suited for production drilling applications where runout control matters. It is installed and serviced by machinists and toolroom technicians.

This chuck is appropriate for use in job shops, maintenance departments, and manufacturing environments where a 3MT spindle is present. Typical installations include floor-mounted and bench-top drill presses, engine lathes with tailstocks, and radial arm drill presses. The integral taper shank mounts directly into a matching 3MT socket without a separate arbor. The keyed design provides positive clamping force, making it well suited for larger-diameter drilling where slip resistance is essential. The Hex 1/4 key engages the chuck ring for tightening and loosening the jaws.

Installation Notes

Power down and lock out the machine before installing or removing the chuck. Clean the taper shank and spindle bore thoroughly before seating to ensure full contact and minimize runout. Drive the taper shank into the spindle socket with a firm, controlled strike using a soft mallet; remove using a drift through the spindle's knockout slot. Do not exceed the rated 8,000 RPM maximum spindle speed for this chuck.
