Techniks 22356 Mini-er Collet Chuck CAT40 ER16

Product Description

The TECHNIKS 22356 is a Mini-ER collet chuck with a CAT40 taper shank, designed for use with ER16 collet series tooling. It delivers a 2.76-inch projection from gauge line to collet nose, with an overall length of 5.44 inches. The chuck accepts collets with a minimum capacity of 1/16 inch and a maximum capacity of 13/32 inch, covering a broad range of small-diameter cutting tools. Machinists and CNC setup technicians install this chuck on CAT40-spindle machining centers where compact, precise ER16 toolholding is required for drilling, reaming, tapping, and light milling operations.

This collet chuck is suited for CNC vertical and horizontal machining centers equipped with CAT40 spindle interfaces. The ER16 collet series is a widely adopted standard, making this chuck a practical choice for production shops running small-diameter tooling in tight-tolerance applications. The 2.76-inch projection provides clearance in workholding setups where tool reach is a factor. It is appropriate for both production and job-shop environments where consistent runout and secure tool retention are priorities.

Key Features

• CAT40 taper shank for direct mounting to CAT40-spindle machining centers
• ER16 collet series compatibility covering 1/16 inch to 13/32 inch tool shank diameters
• 2.76-inch projection suitable for applications requiring extended tool reach
• 5.44-inch overall length for predictable tool-length offset entry
• Mini-ER design supports compact, lightweight toolholding for small-diameter work

Compatibility

Designed for use with ER16 collets on CAT40-spindle CNC machining centers. Accepts any standard ER16 collet within the 1/16-inch to 13/32-inch capacity range.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before mounting or removing the chuck. Use a calibrated torque wrench and the appropriate CAT40 retention knob or drawbar for your specific machine spindle to secure the taper shank. Verify tool runout with a dial indicator after seating the collet and before returning the spindle to service.
