Accupro CY01307000MSC Drill Chuck 1/2 in Tapered JT33

Product Description

The ACCUPRO CY01307000MSC is a keyed drill chuck designed for tapered-mount drilling applications in machine shop and general metalworking environments. It accepts drill bits ranging from 1/16 inch to 1/2 inch (0.0625 to 0.5000 inches) and mounts via a JT33 Jacobs taper. The chuck body is constructed from steel and uses a plain bearing design. The 46 mm sleeve diameter and compact profile make it a practical replacement or spare for drill presses, lathes, and similar machine tool spindles. It ships with a K2 key for bit tightening. Machinists and tool-room technicians are the primary installers of this component.

This drill chuck is suited for light to medium-duty drilling on drill presses and bench machines that accept a JT33 tapered spindle. The keyed design ensures a firm grip on round-shank drill bits across the full capacity range. It is appropriate for both production and maintenance shop environments where reliable, repeatable bit retention is required. The steel body construction holds up to the demands of repetitive metal, wood, and plastic drilling operations.

Installation Notes

Installation and removal of drill chucks should be performed by a qualified machinist or maintenance technician. Power down and lock out the machine before removing or seating the chuck. JT33 tapered chucks are typically seated with a firm mallet strike and removed using a drift key through the spindle slot - avoid striking the chuck sleeve directly. Verify that the taper and spindle bore are clean and free of debris before seating to ensure proper concentricity.
