Parlec C40-16ERF300 ER16 Collet Chuck CAT40 Taper

Product Description

The PARLEC C40-16ERF300 is an ER16 collet chuck with a CAT40 taper shank, designed for precision toolholding on CNC machining centers. It accepts ER16 collets with a capacity range of 0.5 mm to 10 mm (0.0197 to 0.3937 inches), covering a wide range of small-diameter cutting tools. The chuck features a 3-inch projection from gauge line and holds a maximum total indicator runout (TIR) of 0.0002 inches, supporting accurate, repeatable cuts. Through-spindle coolant delivery is built in, directing coolant directly to the cutting zone. Balanced to 25,000 RPM, this chuck suits high-speed machining applications. Installation and adjustment are handled with a standard ER collet wrench.

This chuck is suited for use in vertical and horizontal CNC machining centers equipped with CAT40 spindles. The 3-inch projection and ER16 collet system make it a practical choice for drilling, reaming, and light milling with small-diameter tooling in both production and job-shop environments. The through-coolant design is especially useful in deep-hole drilling and high-speed operations where heat and chip evacuation are critical concerns. Licensed machinists and CNC setup technicians are the typical end users for this style of toolholder.

Compatibility

Designed as an OEM-style toolholder for CNC machining centers with CAT40 taper spindles using the ER16 collet system.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Ensure the spindle is fully powered down and the machine is in a safe state before changing toolholders. Use the appropriate ER16 collet nut wrench and torque arm to seat the collet and nut correctly. Verify through-coolant passages are clear and that the spindle drawbar is properly engaged before resuming operation.
