Accupro PN01308000MSC Keyless Drill Chuck JT6 1/2 Inch

Product Description

The ACCUPRO PN01308000MSC is a keyless drill chuck designed for use on drilling equipment with a JT6 tapered spindle mount. It accepts round-shank drill bits and tooling from 1/32 inch up to 1/2 inch (0.0313 to 0.5000 inches). The chuck uses an internal ball bearing design that supports smooth rotation and consistent grip under load, with a maximum rated spindle speed of 10,000 RPM. The body and jaws are constructed from steel for durability in production and maintenance drilling applications. Machinists, toolroom technicians, and maintenance mechanics install this type of chuck on drill presses, milling machine spindles, and similar equipment requiring a JT6 interface.

This chuck is suited for both light-duty and moderate-production drilling tasks where a keyless design speeds up bit changes without sacrificing clamping force. The keyless collar tightens and releases by hand, which is practical in high-cycle environments where operators swap tooling frequently. With a closed length of 4.055 inches and a sleeve diameter of 1.929 inches, it fits standard JT6 spindle configurations found on benchtop and floor-standing drill presses used in machine shops, fabrication facilities, and industrial maintenance settings.

Compatibility

Designed for use with drill presses, milling machines, and similar equipment equipped with a JT6 tapered spindle mount.

Installation Notes

Installation is performed by a machinist or qualified maintenance technician. Power down and lock out the machine before mounting or removing the chuck from the spindle. The chuck seats onto the JT6 taper by firm hand-press or a light mallet tap against a wooden block — never strike the chuck body directly with a metal hammer. Verify that the taper and bore are clean and free of burrs before seating to ensure full contact and safe operation.
