Techniks CAT40ER16-2.76 ER16 Collet Chuck CAT40

Product Description

The TECHNIKS CAT40ER16-2.76 is a CAT40 taper shank collet chuck designed for ER16 collet series tooling in CNC machining centers. It provides a 2.76-inch projection from the gauge line and accepts collet capacities from 1/16 inch up to 0.406 inches, making it suitable for a range of small-diameter cutting tools including drills, end mills, and reamers. With an overall length of 5.447 inches and a weight of 2.5 pounds, this chuck is built for rigid, accurate tool holding in production environments. A licensed machinist or CNC setup technician installs and torques this chuck as part of a standard tooling assembly.

This collet chuck is used in vertical and horizontal CNC machining centers that accept CAT40 taper tooling. It is suited for general-purpose milling, drilling, and light-duty reaming operations in both job shop and production environments. The ER16 collet series is widely used for smaller-diameter tooling, and the 2.76-inch projection allows clearance in many fixture and workpiece setups where a standard-length holder may not reach.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 machining center spindles
• ER16 collet series accepts tool shanks from 1/16 inch to 0.406 inches
• 2.76-inch projection provides clearance for fixturing and deep-reach applications
• Overall length of 5.447 inches for consistent gage-line reference
• Nut tightening torque specification of 42 ft-lb for proper collet seating
• 2.5-pound construction suitable for balanced high-speed operation

Compatibility

Designed as a direct-fit toolholder for CNC machining centers equipped with CAT40 taper spindles using the ER16 collet system.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Always power down and lock out the machine spindle before installing or removing toolholders. Tighten the ER16 collet nut to the specified torque of 42 ft-lb using a calibrated ER collet nut wrench - do not use improvised tools that could damage the nut or collet taper seats. Inspect the CAT40 taper and spindle bore for contamination or wear before seating the holder.
