Accupro HX01340410MSC Drill Chuck CAT40 1/2 Inch Keyed

Product Description

The ACCUPRO HX01340410MSC is a keyed drill chuck designed for CAT40 tooling systems used in CNC machining centers and vertical milling machines. It accepts round-shank tooling from 1/32 inch (0.0313 inch) up to 1/2 inch (0.5000 inch) and mounts via an integral taper shank in the CAT40 standard. The chuck body is constructed from steel with a plain bearing design and a 54 mm sleeve diameter. It is rated to 8,000 RPM and holds a total indicator runout (TIR) of 0.0012 inch, making it suitable for drilling operations where concentricity matters. A hex 1/4 key is used for tightening and releasing the chuck jaws.

This chuck is intended for production and job-shop environments running CAT40-spindle machining centers performing drilling, reaming, and light boring work. Its integral shank mount eliminates the arbor-to-chuck interface, reducing runout stack-up compared to separate arbor configurations. The keyed design ensures positive jaw clamping under the cutting loads typical of ferrous and non-ferrous drilling in both horizontal and vertical spindle setups. Machinists and CNC setup technicians are the primary installers of this toolholder assembly.

Key Features

• Capacity range of 1/32 inch to 1/2 inch accommodates a wide variety of drill shank sizes
• CAT40 integral shank mount for direct installation into CAT40 spindle tooling systems
• Steel chuck body construction for durability in production environments
• Keyed jaw actuation via hex 1/4 key for positive, repeatable clamping force
• Maximum spindle speed of 8,000 RPM suitable for standard drilling applications
• TIR of 0.0012 inch supports concentricity requirements in precision drilling

Compatibility

Designed for use with CAT40 spindle tooling systems on CNC machining centers and vertical mills equipped with the CAT40 toolholder standard.

Installation Notes

Installation of this chuck into a CAT40 spindle should be performed by a qualified machinist or CNC setup technician following the machine tool manufacturer's toolholder clamping procedures. Power down and lock out the machine spindle before inserting or removing any toolholder. Verify the spindle taper and toolholder taper are clean and free of chips or burrs before seating. Do not exceed the 8,000 RPM maximum rated speed for this chuck assembly.
