Parlec 5UMER16-0156 ER16 Collet 0.1563 Inch

Product Description

The PARLEC 5UMER16-0156 is an ER16 series collet designed for precision workholding in CNC machining and toolholding applications. It accepts a collet size of 0.1563 inches (5/32 inch) with a minimum collet capacity of 0.1365 inches, making it suitable for gripping small-diameter cutting tools and round stock. The collet holds a Total Indicator Runout (TIR) of 0.0002 inches, supporting accurate, repeatable tool positioning. Overall length is 1.082 inches and overall diameter is 0.669 inches. This collet is installed by machinists and tool-room technicians working with ER16-compatible chucks and collet holders on milling machines, lathes, and machining centers.

The 5UMER16-0156 is suited for use in light-duty to medium-duty machining operations where close runout tolerances are required. It is appropriate for residential shop environments and production machine shops alike. Applications include end-mill holding, drill chucking, and reamer retention in ER16 collet chucks. The compact 0.669-inch overall diameter and 1.082-inch overall length allow use in tight-clearance setups and short-nose toolholding configurations.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and power is locked out before changing collets. Clean the collet chuck bore and collet seating surfaces before installation to maintain TIR accuracy. Use the appropriate ER16 torque wrench and spanner nut to seat the collet properly - do not over-tighten by hand or with improvised tools.
