Accupro SPS1603000MSC Keyless Drill Chuck 3MT Taper Shank

Product Description

The ACCUPRO SPS1603000MSC is a keyless drill chuck designed for use on drilling machines, CNC machining centers, and drill presses that accept a 3MT (Morse Taper 3) integral taper shank. It accepts drill bits and tooling from 1/8 inch to 5/8 inch in diameter and uses a ball bearing design for smooth, consistent clamping. The keyless mechanism allows operators to tighten or release tooling by hand without a key, reducing setup time on the floor. At 3.784 pounds with a sleeve diameter of 2.126 inches, this chuck is built for sustained production use in metalworking and fabrication environments. Installation and service are handled by machinists and toolroom technicians.

This chuck fits drilling applications in both production and job-shop settings where a 3MT taper spindle is present. The closed length measures 3.781 inches and the open length extends to approximately 7.328 inches, making it suitable for standard column drill presses and vertical machining center spindles configured for Morse Taper toolholding. A spanner wrench is included. The 6000 RPM maximum speed rating makes it appropriate for a wide range of feed-and-speed combinations across common workpiece materials.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before mounting or removing the chuck, power down the machine and confirm the spindle is fully stopped and locked out per facility lockout/tagout procedures. The taper shank should be cleaned and inspected for burrs or debris before seating to ensure full contact and concentricity. Use a proper drift and mallet to remove the chuck from the spindle; never strike the chuck body directly.
