Parlec 5UMER16-0125 ER16 Collet 0.125 Inch

Product Description

The PARLEC 5UMER16-0125 is an ER16 series collet designed for precision workholding in CNC machining and milling operations. It accepts a nominal collet capacity of 0.125 inches (1/8 inch), with a minimum collet capacity of 0.086 inches, allowing it to grip a range of tool shank diameters. The collet delivers a total indicated runout (TIR) of 0.0002 inches, making it suitable for close-tolerance machining applications. Overall length is 1.082 inches and the overall diameter is 0.669 inches. Licensed machinists and CNC setup technicians are the primary installers of this type of toolholding component.

This ER16 collet fits standard ER16 collet chucks used in CNC machining centers, milling machines, and high-speed spindles across both job shop and production environments. It is appropriate for securing end mills, drill bits, and other round-shank cutting tools within the 0.086 inch to 0.125 inch clamping range. Its compact overall length suits toolholding setups where spindle clearance is a consideration.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle drive before inserting or removing any collet. Ensure the collet chuck bore and collet taper are clean and free of chips or debris before seating the collet. Use a calibrated collet nut wrench to achieve proper clamping torque as specified by the chuck manufacturer.
