Accupro HX01340200MSC Drill Chuck BT40 Integral Shank

Product Description

The ACCUPRO HX01340200MSC is a keyed drill chuck designed for CNC machining centers and milling machines using a BT40 spindle interface. It accepts drill and tooling shanks from 1/32 inch (0.0313 inch) up to 1/2 inch (0.5000 inch) capacity, making it suitable for a wide range of hole-making operations. The chuck features an integral taper shank mount, a 54 mm sleeve diameter, and a plain bearing design. Maximum spindle speed is 8,000 RPM. Total indicator runout (TIR) is rated at 0.0012 inch, supporting consistent hole accuracy across production and job-shop applications. The unit weighs 4.5 pounds and is constructed of steel.

This chuck is intended for use in vertical and horizontal machining centers equipped with a BT40 taper spindle. Typical applications include drilling, reaming, and light boring in ferrous and non-ferrous materials. The keyed design using a Hex 1/4 key provides positive grip on the tool shank, making it appropriate for production environments where tool pullout is a concern. Closed length is approximately 105 mm and open length is approximately 96 mm, factors that affect reach and clearance in confined workpiece setups. Installation and tool changes are performed by qualified CNC machinists or tool crib personnel.

Installation Notes

This chuck is installed and removed by qualified machinists following the machine tool manufacturer's spindle service procedures. Power down and lock out the machining center before any chuck change. Ensure the spindle taper and chuck shank are clean and free of chips or burrs before seating. Use the supplied Hex 1/4 key to tighten tooling to the manufacturer's specified procedure; do not use impact tools on the chuck body.
