Techniks 22359 Mini-er Collet Chuck CAT40 ER16

Product Description

The TECHNIKS 22359 is a Mini-ER collet chuck with a CAT40 taper shank, designed for use with ER16 series collets. It provides a 6-inch projection from the spindle face and accepts collet capacities ranging from 1/16 inch to 13/32 inch. Total overall length is 8.68 inches. This tool holder is installed by machinists and CNC setup technicians in milling and machining center applications where extended reach or clearance is required in the work envelope.

This collet chuck is suited for vertical and horizontal machining centers equipped with CAT40 spindles. The ER16 collet series supports a wide range of small-diameter cutting tools, making this holder appropriate for finish milling, drilling, reaming, and light-duty contouring operations. The extended 6-inch projection is useful when tooling must reach deep pockets or clear fixture components without spindle interference.

Key Features

• CAT40 taper shank for direct mounting in CAT40-spindle machining centers
• ER16 collet series compatibility with capacity range from 1/16 inch to 13/32 inch
• 6-inch projection for extended reach in deep-pocket and fixture-clearance applications
• 8.68-inch overall length for predictable tool-length offset entry
• Mini-ER collet system for compact, secure tool clamping at smaller diameters

Compatibility

Designed for use with ER16 series Mini-ER collets in machining centers equipped with CAT40 taper spindles.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Confirm the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool holder. Use the appropriate CAT40 pull stud and a properly calibrated torque wrench with a collet chuck holding fixture when tightening the collet nut. Verify tool-length offset in the machine controller after setup before initiating any cutting cycle.
