Accupro SPS1604000MSC Keyless Drill Chuck 4MT Taper Shank

Product Description

The ACCUPRO SPS1604000MSC is a keyless drill chuck designed for use on drilling machines, lathes, and machining centers equipped with a 4MT (Morse Taper 4) spindle. It accepts drill bits and round-shank tooling from 1/8 inch to 5/8 inch capacity, with a ball bearing design that supports smooth, consistent jaw actuation without a key. The integral taper shank mounts directly into a 4MT spindle bore, eliminating the need for an adapter. Rated to 6000 RPM, this chuck is built for production-level drilling operations where speed and repeatability matter. The steel construction and 0.0016 inch TIR specification make it a solid choice for general-purpose and precision drilling work.

This chuck is suited for vertical machining centers, drill presses, radial arm drills, and lathes configured with a 4MT spindle. Typical applications include production drilling in metal fabrication, machine shops, and tool rooms where a keyless design improves cycle time between tool changes. The 5/8 inch maximum capacity covers the majority of common twist drill and reamer shank sizes used in those environments. Machinists and machine tool operators are the primary installers and users of this chuck.

Installation Notes

Installation is performed by qualified machinists or machine tool operators. Power down and lock out the machine before mounting or removing the chuck from the spindle. Ensure the 4MT taper and spindle bore are clean and free of burrs or debris before seating the shank. Use a proper drift and mallet for removal to avoid damaging the taper surfaces.
