Techniks 22307-9 ER25 Collet Chuck CAT50 9 Inch Projection

Product Description

The TECHNIKS 22307-9 is an ER25 collet chuck with a CAT50 taper shank, designed for use in CNC machining centers and milling applications. It features a 9-inch projection and an overall length of 13 inches, making it suitable for deep-reach cutting operations where standard-length holders cannot access the workpiece. The ER25 collet system accepts tooling with shank diameters from 3/32 inch up to 3/4 inch. This chuck is installed by machinists and CNC operators working in production and job-shop environments requiring extended reach with reliable tool retention.

This collet chuck is used in vertical and horizontal machining centers equipped with CAT50 spindle interfaces. The extended 9-inch projection suits deep cavity milling, long-reach boring, and similar operations where the spindle nose must be kept clear of fixtures or workpiece features. It is compatible with the full range of ER25 collets, giving operators flexibility across a wide variety of tool shank sizes within the ER25 capacity range.

Key Features

• CAT50 taper shank for use in standard CAT50 spindle interfaces
• ER25 collet system with capacity range from 3/32 inch to 3/4 inch
• 9-inch projection for deep-reach and clearance-critical machining operations
• 13-inch overall length for extended tool positioning
• Weighs 11 pounds for solid, vibration-resistant tool holding at the spindle

Compatibility

Designed for use in machining centers with a CAT50 spindle taper. Accepts all standard ER25 collets with tool shank diameters from 3/32 inch to 3/4 inch.

Installation Notes

Installation and removal of taper-shank toolholders should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked. Use a proper toolholder tightening fixture and the correct drawbar torque procedure specified by the machine tool manufacturer. Inspect the taper shank and spindle bore for nicks, chips, or contamination before seating the holder. Never use an unclean or damaged taper interface, as this will affect runout and tool retention force.
