Accupro PN01005000MSC Keyless Drill Chuck JT2 3/8 Inch

Product Description

The ACCUPRO PN01005000MSC is a keyless drill chuck designed for precision drilling applications in machine shop and industrial tool environments. It accepts drill bits and tooling from 1/32 inch up to 3/8 inch capacity and mounts via a JT2 tapered shank, making it a direct-fit replacement or upgrade for compatible drill presses, lathes, and milling machine spindles. The keyless design allows for hand-tightening without a chuck key, speeding up bit changes on the floor. Internal ball bearings support smooth, concentric rotation at speeds up to 15,000 RPM. The chuck body is constructed from steel for durability under repeated use. Installation and maintenance are typically handled by machinists, tool and die technicians, or maintenance mechanics.

This chuck is suited for light-to-medium drilling operations where fast tooling changes and consistent runout matter. The JT2 taper mount is a widely used standard on benchtop and floor-standing drill presses as well as some lathe tailstocks and milling attachments. The 1.693 inch sleeve diameter and compact closed length of 3.504 inches make it compatible with setups where spindle clearance is a consideration. Professionals sourcing a keyless replacement for a worn or damaged JT2-mount chuck will find this a direct drop-in option.

Key Features

• Keyless design enables rapid bit changes without a chuck key
• Accepts tooling from 1/32 inch to 3/8 inch capacity
• JT2 tapered mount for compatibility with standard spindle tapers
• Ball bearing construction supports smooth, true rotation
• Rated to 15,000 RPM for use with high-speed drilling equipment
• Steel chuck body for resistance to wear and shop abuse

Compatibility

Designed as an OEM-style replacement or upgrade chuck for drill presses, lathe tailstocks, and milling attachments equipped with a JT2 tapered spindle bore. Verify your machine spindle taper designation before installation.

Installation Notes

Installation requires powering down and fully locking out the machine before any chuck removal or seating work. The JT2 taper is seated by firm hand pressure or a soft mallet strike to the chuck body — never strike the sleeve directly. Removal typically requires a drift key through the spindle slot. Confirm spindle taper designation matches JT2 before mounting to avoid damage to the spindle bore.
