Parlec ER25-0118 ER25 Collet 0.1181 Inches 3.00mm

Product Description

The PARLEC ER25-0118 is an ER25-series collet designed to hold tooling at a nominal clamping diameter of 0.1181 inches (3.00mm). It provides concentric, secure tool retention in ER25-compatible collet chucks used on CNC machining centers, mills, and lathes. The collet features a minimum collet capacity of 0.0787 inches (2.0mm) and an overall length of 1.338 inches, making it suited for close-tolerance gripping of small-diameter end mills, drills, reamers, and similar round-shank cutting tools. Machinists and CNC setup technicians rely on ER-series collets for their broad clamping range and repeatable runout performance in production environments.

This collet is intended for use in light-duty to general-purpose machining applications where small-diameter tooling must be held with precision. It fits standard ER25 collet chucks found in vertical machining centers, horizontal mills, and multi-axis turning centers in both job-shop and production settings. The ER25 taper is one of the most widely adopted collet standards in CNC and manual machining, making this collet a common replacement and stocking item for tool cribs and machine shops.

Compatibility

Designed as an OEM-style replacement collet for use with standard ER25-series collet chucks on CNC mills, machining centers, and lathes.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and the chuck body is clean and free of chips or debris before seating the collet. Insert the collet into the chuck nut before threading onto the chuck body, following standard ER collet assembly procedure. Inspect the collet for wear, cracks, or deformation before each use, and replace if any damage is found.
