Accupro HX01350210MSC Drill Chuck BT50 1/2 Inch Keyed

Product Description

The ACCUPRO HX01350210MSC is a keyed drill chuck designed for CNC machining centers and milling machines using BT50 tooling. It accepts drill shanks from 1/32 inch (0.0313 inch) up to 1/2 inch (0.5000 inch), covering a wide range of drilling and boring applications. The chuck uses an integral taper shank mount for direct spindle connection with no separate arbor required. The steel body and plain bearing construction are suited for high-speed operation up to 8,000 RPM. A hex 1/4 key is used for tightening. Sleeve diameter measures 54 millimeters and closed length is 116 millimeters. Installed by machinists and CNC setup technicians in production and job-shop environments.

This chuck is intended for use in machining centers equipped with BT50 spindle interfaces. It is appropriate for drilling operations in steel, aluminum, and similar materials where a keyed chuck is preferred over a keyless design for positive grip retention at higher torque loads. The integral shank design eliminates the need for a separate adapter, reducing runout and simplifying tooling changeouts. Typical applications include production drilling, step drilling, and reaming setups on vertical or horizontal machining centers.

Key Features

• Capacity range from 1/32 inch to 1/2 inch (0.0313 to 0.5000 inch decimal)
• BT50 integral taper shank mount for direct spindle installation without an arbor
• Keyed chuck design with hex 1/4 key for secure tool clamping at higher torque
• Maximum spindle speed of 8,000 RPM
• Total indicator runout (TIR) of 0.0012 inch for consistent drill positioning
• Steel chuck body with plain bearing construction

Compatibility

Designed for use with BT50 spindle interfaces on CNC machining centers and milling machines that accept BT50 integral shank tooling.

Installation Notes

Installation and removal of BT50 tooling must be performed with the machine spindle fully stopped and the machine placed in a locked-out, de-energized state per applicable lockout/tagout procedures. Use the correct hex key to seat and tighten the drill securely before operation. Inspect the taper shank and spindle bore for chips, burrs, or contamination before mounting, as surface debris directly affects runout and chuck seating. Consult the machine tool manufacturer specifications for drawbar torque and tool retention requirements applicable to BT50 tooling on the specific spindle.
