Parlec 5UMER32-0125 ER32 Collet 0.125 Inch

Product Description

The PARLEC 5UMER32-0125 is an ER32 series collet designed for precision workholding in CNC machining and milling applications. It accepts a nominal clamping diameter of 0.125 inches (1/8 inch) with a minimum collet capacity of 0.086 inches, giving machinists flexibility when gripping small-diameter tooling. Total indicator runout (TIR) is held to 0.0002 inches, supporting tight tolerances on finishing and drilling operations. Overall length is 1.574 inches. This collet is installed and serviced by machining technicians and tool room personnel working with ER32-compatible spindles and tool holders.

The 5UMER32-0125 is suited for use in vertical machining centers, CNC mills, and manual milling machines equipped with ER32 collet chucks or tool holders. It is a standard choice for gripping end mills, drills, reamers, and taps in the 1/8 inch shank range. Applications span precision job shops, production machining, and toolroom environments where consistent runout and repeatable tool-to-tool setup are required.

Installation Notes

Installation is performed by qualified machining technicians familiar with ER collet systems. Before installing or removing the collet, ensure the machine spindle is fully stopped and locked out per shop lockout/tagout procedures. Seat the collet into the nut before threading onto the holder, and tighten using a proper ER collet wrench to the chuck manufacturer's specified torque range. Inspect the collet bore and seating surfaces for chips or damage before each use to maintain TIR performance.
