Accupro QCK-1 IK/CAT50 Tapping Chuck CAT50 Rigid

Product Description

The ACCUPRO QCK-1 IK/CAT50 is a rigid tapping chuck with a CAT50 taper shank interface, designed for use on CNC machining centers and tapping machines where precise thread production is required. The chuck accepts taps ranging from M3 to M12 (up to 9/16 inch), covers 1/8 inch pipe taps, and delivers a projection of 3.445 inches (87.5 mm) from the spindle face. Through-coolant capability keeps the cutting zone clear during operation. A Size 1 tap adapter connects the chuck body to the tap holder. Machinists and CNC operators install this unit as a direct taper-mount toolholder for production tapping applications.

This tapping chuck is suited for rigid tapping cycles on vertical and horizontal machining centers equipped with a CAT50 spindle. The quick-change design reduces tap changeover time in production environments. The 1.2598-inch nose diameter accommodates standard tap adapter configurations. Typical applications include threading steel, aluminum, and other workpiece materials in job shop and production machining settings. This chuck is intended for professional machinists and CNC programmers running tapping operations that demand repeatable thread quality and minimal runout.

Key Features

• Rigid tapping style for synchronous tapping cycles on CNC machining centers
• CAT50 taper shank for direct spindle mounting without an intermediate adapter
• M3 to M12 tap capacity (up to 9/16 inch), including 1/8 inch pipe taps
• Through-coolant compatible to extend tap life and clear chips during operation
• Quick-change interface for fast tap adapter swaps in production environments
• 3.445-inch projection provides clearance for workpiece fixtures and part features

Compatibility

Designed for use with CAT50 spindle-equipped CNC machining centers. Accepts Size 1 tap adapters. Compatible with taps from M3 to M12 and pipe taps at 1/8 inch.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing the toolholder. Use the appropriate CAT50 retention knob and a calibrated torque wrench per the machine tool manufacturer's specifications when securing the drawbar. Verify through-coolant port alignment with the machine spindle coolant supply before running.
