Accupro PHI0704100MSC Drill Chuck JT1 Tapered Mount

Product Description

The ACCUPRO PHI0704100MSC is a keyed drill chuck designed for precision drilling applications requiring consistent grip and concentricity across a wide capacity range. It accepts drill bits and tooling from 0.012 to 0.291 inches, making it suitable for both fine-diameter and standard drill shanks. The chuck uses a tapered mount with a JT1 taper interface and operates with a K1T key for tightening. Internal ball bearings support smooth, repeatable jaw movement. The sleeve diameter measures 30 mm, and the chuck body is constructed from stainless steel for durability in shop and industrial environments. Machinists, tool and die technicians, and maintenance trades install this type of chuck on drill presses, lathes, and milling machine spindles.

This drill chuck is suited for use in machine shop environments, industrial maintenance settings, and precision fabrication operations. It covers a broad capacity range that accommodates both small-diameter bits used in detail work and larger bits used in general drilling. The JT1 tapered mount is a standard interface found on a variety of drilling spindles and arbors in light-duty and bench-top drilling equipment. The hybrid key type designation indicates compatibility with the included K1T key for jaw actuation.

Compatibility

Designed for use with JT1 taper spindles and arbors on drill presses, lathes, and similar drilling equipment where a keyed chuck with a 0.012 to 0.291 inch capacity range is required.

Installation Notes

Installation is performed by machinists or qualified maintenance technicians. Power down and de-energize the machine fully before mounting or removing the chuck from the spindle. The JT1 taper should be cleaned and inspected for burrs or debris before seating the chuck to ensure full contact and concentricity. Do not strike the chuck body directly with a metal hammer when seating or removing the taper; use a proper drift or soft-face mallet to avoid damage to the jaws or bearing assembly.
