Parlec ERS25-0393 ER25 Collet 10 Mm Bore

Product Description

The PARLEC ERS25-0393 is an ER25 series collet designed for precision workholding in CNC machining centers, milling machines, and drilling operations. With a 10 mm bore size and an overall length of 1.338 inches, this collet provides secure, concentric clamping of cutting tools and round-shank tooling. The ER25 collet standard is one of the most widely used collet formats in machine shops, and this unit is built to deliver consistent runout performance in production environments. Machinists and tooling specialists working with ER25-compatible collet chucks will find this a direct-fit replacement or addition to existing tooling setups.

This collet is suited for use in ER25 collet chucks installed on vertical and horizontal machining centers, drill presses, and tapping machines in both job-shop and production environments. It accommodates 10 mm shank tooling including end mills, drills, reamers, and taps. The ER25 series is commonly specified in light to medium-duty material removal applications across a wide range of workpiece materials.

Installation Notes

ER25 collets are installed by qualified machinists or tooling technicians using an ER25 collet chuck and the appropriate spanner nut and wrench. Always ensure the machine spindle is fully stopped and the tool is properly de-energized before changing collets. Inspect the collet bore and the chuck bore for chips or debris before seating the collet. Do not exceed the rated clamping torque for the collet chuck manufacturer specifications.
