Techniks 22293F ER20 Collet Chuck CAT50 6 in Projection

Product Description

The TECHNIKS 22293F is an ER20 collet chuck with a CAT50 taper shank, designed for use in CNC machining centers that require precise tool holding with through-coolant capability. The chuck accepts ER20 series collets with a clamping range of 1/16 inch to 1/2 inch, covering a wide variety of tooling diameters. With a 6-inch projection and a 10-inch overall length, this chuck is suited for deep-reach applications where standard-length holders fall short. Through-coolant capability allows cutting fluid to be delivered directly to the cutting zone, improving chip evacuation and tool life. Machinists and CNC setup technicians install this holder in CAT50 spindle machines.

This collet chuck is intended for use in industrial CNC machining environments, including vertical and horizontal machining centers equipped with CAT50 spindle interfaces. The extended 6-inch projection makes it well suited for cavity work, deep pocket milling, and applications where the spindle nose must clear fixtures or workpiece features. The ER20 collet system is a common standard in production and job shop settings. Through-coolant support is relevant in applications involving carbide end mills, drills, and reamers where heat and chip buildup must be controlled.

Key Features

• CAT50 taper shank for compatibility with CAT50 spindle interfaces on CNC machining centers
• ER20 collet series with a clamping range of 1/16 inch to 1/2 inch
• 6-inch projection for extended reach into deep pockets or past large fixtures
• 10-inch overall length
• Through-coolant design delivers coolant directly to the cutting edge
• Weighs 8.7 pounds

Compatibility

Designed for use with ER20 series collets in CAT50 spindle machining centers. Accepts tooling with shank diameters from 1/16 inch to 1/2 inch.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. The spindle must be powered down and brought to a full stop before changing tool holders. Use the appropriate CAT50 retention knob and torque the drawbar according to the machine manufacturer specifications. Verify through-coolant port alignment with the machine spindle coolant supply before use.
