Techniks 22303F ER25 Collet Chuck CAT50 Taper Shank

Product Description

The TECHNIKS 22303F is an ER25 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 ER25 collets with a clamping range from 3/32 inch to 3/4 inch, covering a wide variety of cutting tool shank sizes. With a 4-inch projection from gauge line and an overall length of 8 inches, this chuck provides clearance for deep-reach applications while maintaining rigidity. Weighing 8 pounds, it is built for production environments where consistent tool runout and coolant delivery are critical to surface finish and tool life.

This collet chuck is suited for horizontal and vertical machining centers equipped with CAT50 spindles. It is commonly used in heavy-duty milling, drilling, reaming, and tapping operations where through-spindle coolant is needed to extend tool life and clear chips from deep bores or pockets. The 4-inch projection makes it appropriate for workpieces requiring additional reach between the spindle face and the cutting zone. Installation and tool changes are performed by machinists and CNC setup technicians working in production or job-shop environments.

Key Features

• ER25 collet system accepts shanks from 3/32 inch to 3/4 inch
• CAT50 taper shank for direct spindle mounting on CAT50 machining centers
• Through coolant design delivers coolant directly to the cutting edge
• 4-inch projection for deep-reach and clearance-critical applications
• 8-inch overall length for extended tool positioning

Compatibility

Designed for use with CAT50 spindle machining centers that support ER25 collets. Accepts ER25 collet series with a minimum capacity of 3/32 inch and a maximum capacity of 3/4 inch.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The spindle must be fully powered down and at a complete stop before mounting or removing the chuck. Use the appropriate CAT50 pull stud and a calibrated torque wrench rated for the machine spindle specification. Verify through-coolant port alignment with the machine spindle before tightening to ensure unobstructed coolant flow to the tool.
