Accupro HX01650200MSC Drill Chuck BT50 1/8-5/8 in Keyed

Product Description

The ACCUPRO HX01650200MSC is a keyed drill chuck designed for CNC machining centers and milling applications requiring a BT50 taper shank interface. It accepts drill shanks from 1/8 inch (0.125 inch) to 5/8 inch (0.625 inch) in diameter and delivers a total indicator runout (TIR) of 0.0012 inch, supporting consistent hole quality across a range of drill sizes. The chuck body is constructed from steel and uses a plain bearing design. A hex 1/4 key is used to tighten and release tooling. Rated to 8000 RPM, this chuck suits high-speed drilling operations in production shop environments. Installation and setup are performed by qualified CNC machine operators and toolroom machinists.

This drill chuck is suited for use in BT50-spindle vertical machining centers, horizontal machining centers, and drill presses equipped with a BT50 taper interface. The integral shank mount eliminates the need for a separate arbor, simplifying tool assembly and reducing stack-up length. It is appropriate for general-purpose drilling in steel, aluminum, and similar workpiece materials in both job-shop and production machining settings.

Key Features

• Capacity range of 1/8 inch to 5/8 inch accommodates a wide variety of drill shank sizes
• BT50 integral taper shank mounts directly to compatible spindles without a separate arbor
• TIR of 0.0012 inch supports accurate hole placement and consistent drill performance
• Maximum rated speed of 8000 RPM suitable for production drilling cycles
• Keyed design with hex 1/4 key provides positive clamping force on the tool shank
• Steel chuck body for durability in metal-cutting environments

Compatibility

Designed for use with machining center spindles that accept a BT50 taper interface. Verify spindle taper specification before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before mounting or removing the chuck. Ensure the BT50 shank and spindle taper are clean and free of chips, burrs, or coolant residue before seating the tool. Follow the machine tool manufacturer torque specifications for the retention knob and drawbar system.
