Parlec ER40-0125 ER40 Collet 1/8 Inch

Product Description

The PARLEC ER40-0125 is an ER40 series collet designed for precision workholding in CNC machining and manual milling applications. With a nominal collet size of 0.125 inches (1/8 inch) and a minimum collet capacity of 0.086 inches, this collet accommodates a range of small-diameter tooling within that clamping range. The overall length measures 1.811 inches. Machinists, toolroom technicians, and CNC setup personnel install this collet into compatible ER40 collet chucks mounted on milling machines, machining centers, lathes, and similar machine tool spindles.

This collet is suited for light to medium-duty material removal operations where accurate tool concentricity and repeatable clamping force are required. The ER40 series is a widely adopted standard in both job shop and production environments. It fits ER40-designated collet chucks and toolholders used across a broad range of machine tool platforms in residential shop, commercial shop, and industrial facility settings.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before changing or seating a collet. Ensure the collet and chuck bore are clean and free of chips or debris before seating to maintain runout tolerance. Do not overtighten the collet nut by hammer or impact method - use the appropriate spanner wrench for the ER40 collet nut size.
