Techniks 22291F ER20 Collet Chuck CAT50 Taper Shank

Product Description

The TECHNIKS 22291F is an ER20 collet chuck with a CAT50 taper shank, designed for use in CNC machining centers that require secure, repeatable toolholding. The chuck accepts ER20 collets with a capacity range of 1/16 inch to 1/2 inch, covering a broad selection of cutting tool shanks. Projection from gauge line measures 4 inches, and overall length is 8 inches. Through-coolant capability allows directed coolant flow to the cutting edge, supporting longer tool life and improved chip evacuation in demanding metal-cutting operations. Weighing 7.9 pounds, this is a solid, production-grade toolholder built for high-cycle machining environments.

The TECHNIKS 22291F is suited for milling, drilling, reaming, and tapping operations on vertical and horizontal CNC machining centers equipped with CAT50 spindle interfaces. The ER20 collet system is widely used in production shops for its clamping range versatility and collet availability. The 4-inch projection makes it appropriate for applications requiring clearance from the spindle face, such as deep-pocket milling or workholding interference avoidance. Licensed machinists and CNC setup technicians are the primary users of this toolholder.

Key Features

• CAT50 taper shank for direct mounting in CAT50-configured CNC spindles
• ER20 collet system with clamping range from 1/16 inch to 1/2 inch
• 4-inch projection from gauge line provides clearance for deep-pocket and obstructed setups
• Through-coolant design delivers coolant directly to the cutting zone
• 8-inch overall length suits standard CAT50 tooling configurations
• 7.9-pound construction reflects solid, production-ready build quality

Compatibility

Designed as an OEM-style toolholder for CNC machining centers equipped with a CAT50 spindle interface. Accepts standard ER20 series collets.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before loading or removing the toolholder. Use a calibrated torque wrench and the appropriate ER20 collet nut spanner when tightening the collet nut - follow the collet manufacturer torque guidelines, not estimated hand-tight values. Verify through-coolant passages are clear and properly connected before initiating a cutting cycle.
