Accupro CSS04121010MSC Drill Chuck JT0 Tapered Mount

Product Description

The ACCUPRO CSS04121010MSC is a keyed drill chuck designed for precision drilling applications on lathes, drill presses, and milling machines. It accepts drill bit shanks ranging from 0.02 to 0.156 inches in diameter and mounts via a JT0 Jacobs taper. The chuck body is constructed from stainless steel, providing resistance to corrosion and wear in shop environments. A K0M chuck key is required for tightening and releasing tooling. Plain bearing construction keeps the design straightforward and serviceable. This chuck is suited for machinists, tool and die technicians, and precision drilling work where repeatable chuck capacity and a secure taper mount are required.

This drill chuck is used in light-duty precision drilling setups where a JT0 taper mount is specified. Typical applications include small bench-top drill presses, watchmaking lathes, jewelers lathes, and CNC tooling setups that use Jacobs taper arbors. The compact sleeve diameter of 22 millimeters and closed length of approximately 1.38 inches make it well suited for confined spindle clearances. It is appropriate for both production shop environments and precision hobby or instrument machining operations.

Key Features

• Capacity range of 0.02 to 0.156 inches accommodates small-diameter drill bits and tooling
• JT0 Jacobs taper mount provides a secure, repeatable connection to compatible arbors
• Stainless steel chuck body resists corrosion and wear in machine shop conditions
• Keyed design with K0M chuck key allows positive clamping force on tooling
• Plain bearing construction simplifies maintenance and service
• Compact 22 mm sleeve diameter suits tight spindle clearance applications

Compatibility

Designed for use with JT0 Jacobs taper arbors on drill presses, lathes, and milling machines that specify a JT0 tapered mount chuck.

Installation Notes

Installation is performed by machinists or qualified machine tool technicians. Power down and lock out the machine spindle before seating or removing the chuck from the arbor. Press the chuck firmly onto the JT0 taper arbor using a mallet and a soft-faced driver or draw bar as specified by the machine manufacturer. Do not use the chuck key to force the taper engagement. Inspect the taper surfaces for burrs or contamination before installation.
