Accupro HX01304000MSC Drill Chuck 4MT Taper Shank 1/2 in

Product Description

The ACCUPRO HX01304000MSC is a keyed drill chuck designed for use on taper-shank tooling applications in machining and fabrication environments. It accepts drill bits and round-shank tooling from 1/32 inch (0.0313 inch) up to 1/2 inch (0.5000 inch) capacity, making it well suited for a wide range of hole-making operations. The chuck mounts via an integral 4MT (Morse Taper 4) shank and uses a Hex 1/4 key for tightening and releasing tooling. Constructed from steel, this chuck delivers consistent grip across its full capacity range. Installation and operation are handled by machinists, tool and die makers, and shop technicians working with drill presses, mills, or lathes equipped with a 4MT spindle.

This chuck is intended for use on machine tool spindles that accept a 4 Morse Taper interface. Typical applications include production drilling, step drilling, and reaming operations on drill presses and milling machines in both job-shop and production environments. The keyed design provides secure tooling retention at spindle speeds up to 8000 RPM, which supports a broad range of ferrous and non-ferrous workpiece materials. The plain bearing construction is appropriate for standard drilling loads where high-precision runout control is required.

Key Features

• Capacity range of 1/32 inch to 1/2 inch accommodates a wide variety of drill and round-shank tooling
• Integral 4MT taper shank mounts directly into compatible spindle sockets without a separate adapter
• Keyed chuck with Hex 1/4 key provides positive tooling lock and repeatable release
• Maximum spindle speed rating of 8000 RPM supports standard production drilling operations
• Total Indicator Runout (TIR) of 0.0012 inch ensures consistent concentricity across the capacity range
• Steel chuck body provides durability in shop environments

Compatibility

Designed to mount on machine tool spindles with a 4 Morse Taper (4MT) socket, including drill presses, milling machines, and lathes configured for taper-shank chuck mounting.

Installation Notes

Installation is performed by a machinist or qualified shop technician. Power down and lock out the machine spindle before installing or removing the chuck. Seat the taper shank fully into the spindle socket and verify it is properly engaged before operation. Inspect the taper bore and shank for burrs or contamination prior to installation, as debris in the taper interface will affect runout and retention.
