Accupro CY01911000MSC Keyed Drill Chuck 3/4 in Threaded

Product Description

The ACCUPRO CY01911000MSC is a keyed drill chuck designed for threaded-mount spindles with a 5/8-16 thread size. It accepts round-shank drill bits and tooling from 13/64 inch (0.1969 inches) up to 3/4 inch (0.7500 inches) in diameter. The chuck body is constructed of steel and uses a plain bearing design for consistent grip and repeatable tool seating. The sleeve diameter measures 65 mm, and the chuck uses a K4 key for tightening and releasing tooling. Machinists, tool-and-die technicians, and maintenance mechanics working with drill presses, mills, or lathes configured for threaded-spindle chucks will find this a direct-fit replacement or upgrade option.

This chuck is suited for bench-top and floor-standing drill presses, as well as milling machines and other machine tool spindles threaded to the 5/8-16 standard. Its capacity range covers the majority of common fractional and metric drill bit shanks used in general metalworking, woodworking, and maintenance applications. The keyed design provides higher clamping force retention compared to keyless alternatives, making it appropriate for higher-torque drilling operations in production or shop environments.

Key Features

• Capacity range from 13/64 inch to 3/4 inch accommodates a wide variety of drill bit shank sizes

Compatibility

Designed as a threaded-mount replacement or upgrade chuck for drill press and machine tool spindles with a 5/8-16 threaded spindle nose.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Power down and lock out the machine at the main disconnect before removing the existing chuck or mounting this unit. Thread the chuck onto the spindle nose by hand first to confirm thread engagement, then tighten securely according to the machine manufacturer's spindle torque guidance. Verify runout with a dial indicator after installation before returning the machine to service.
