Parlec ER16-0125 ER16 Collet 0.125 Inch Bore

Product Description

The PARLEC ER16-0125 is an ER16 series collet with a 0.125 inch (1/8 inch) bore capacity, designed for use in CNC machining centers, milling machines, and high-speed spindle toolholding systems. This collet provides secure workpiece or cutting tool clamping within the ER16 collet nut and chuck system. The overall length is 1.082 inches and the overall diameter is 0.669 inches. Minimum collet capacity is 0.086 inches, giving the collet a clamping range suited to small-diameter end mills, drills, and reamers. Installation is performed by machinists and CNC setup technicians on production and job shop equipment.

The ER16-0125 is intended for light-duty to medium-duty machining applications where a small-bore ER16 collet is required. Typical use cases include precision drilling, milling, and reaming operations on CNC machining centers or manual milling machines equipped with ER16-compatible chucks or toolholders. This collet is well-suited to shops running small-diameter tooling in aluminum, steel, and similar materials where accurate tool runout and reliable clamping force are required for consistent results.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before inserting or removing collets. Seat the collet fully into the collet nut before threading onto the chuck body to prevent cross-threading or collet damage. Inspect the collet bore and seating surfaces for chips or debris before each use to ensure accurate tool runout.
