Accupro CKS1306020MSC Keyless Drill Chuck JT2 1/2 Inch

Product Description

The ACCUPRO CKS1306020MSC is a keyless drill chuck designed for use with tapered-spindle drilling equipment. It accepts drill bits and accessories ranging from 1/32 inch (0.0313 inch) up to 1/2 inch in shank diameter, covering the most common range used in production and maintenance drilling applications. The chuck mounts via a JT2 Jacobs taper and uses an internal ball bearing assembly to provide consistent grip and smooth jaw actuation. The sleeve diameter measures 47 millimeters and the chuck body is constructed from steel. Licensed tradespeople and machining technicians handling drill press, mill, or lathe tailstock setups are the primary installers of this component.

This chuck is suited for light-to-medium duty drilling operations across industrial, maintenance, and fabrication environments. The keyless design allows bit changes by hand without a separate chuck key, reducing downtime during repetitive drilling tasks. The JT2 taper mount is a widely used spindle interface found on drill presses, milling machines, and lathe tailstocks in both shop and field service settings. The ball bearing construction supports accurate, concentric bit retention during extended use.

Key Features

• Keyless operation allows fast, tool-free bit changes by hand
• Capacity range of 1/32 inch to 1/2 inch covers standard drill and accessory shank sizes
• JT2 Jacobs taper mount for secure, repeatable spindle engagement
• Ball bearing internals support smooth jaw travel and consistent clamping force
• Steel chuck body provides durability in production and maintenance environments
• 47 millimeter sleeve diameter for positive hand grip during bit changes

Compatibility

Designed for use with drilling equipment fitted with a JT2 Jacobs taper spindle. Verify spindle taper specification on the host machine before installation. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation is typically performed by machinists or maintenance technicians familiar with taper-mount tooling. Power down and lock out the host machine before seating or removing the chuck from the spindle. The JT2 taper is driven onto the spindle with a controlled mallet strike against a protected chuck body surface and removed using a taper drift through the spindle drift slot. Inspect the mating taper surfaces for burrs or contamination before installation to ensure full seating and safe operation.
