Techniks 22233 ER16 Collet Chuck CAT40 Taper Shank

Product Description

The TECHNIKS 22233 is an ER16 collet chuck with a CAT40 taper shank, designed for use in CNC machining centers and vertical milling applications. It accepts ER16 collets with a capacity range of 1/16 inch to 13/32 inch, making it suitable for small-diameter tooling such as drills, end mills, and reamers. The chuck features an 8-inch projection from the spindle face, providing extended reach for deep-cavity work. With an overall length of 10.68 inches and a total weight of 1 pound, it is a compact, lightweight option for precision tool holding in production environments. Installation and balancing are handled by qualified CNC machinists or toolroom technicians.

This chuck is used in CAT40-spindle machining centers in both job-shop and production environments. The extended 8-inch projection makes it well suited for milling or drilling operations where standard-length holders cannot reach the workpiece due to fixture height or part geometry. The ER16 collet system provides reliable clamping across the full capacity range, supporting general-purpose tooling setups in light to moderate cutting conditions.

Key Features

• ER16 collet system with capacity from 1/16 inch to 13/32 inch
• CAT40 taper shank for direct spindle mounting on compatible machining centers
• 8-inch projection for extended reach in deep-cavity or tall-fixture applications
• 10.68-inch overall length for rigid tool positioning
• Lightweight at 1 pound for reduced spindle load

Compatibility

Designed for use with CAT40-spindle CNC machining centers and compatible with the ER16 collet series. Accepts ER16 collets sized from 1/16 inch to 13/32 inch.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Spindle must be fully stopped and the machine placed in an appropriate safe state before mounting or removing the chuck. Use the correct CAT40 pull stud and a properly calibrated torque wrench on the retention knob per the machining center manufacturer specifications. Inspect the taper shank and spindle bore for chips or contamination before seating the holder.
