Parlec ERS25-0551 ER25 Collet 14 Mm

Product Description

The PARLEC ERS25-0551 is an ER25 series collet designed for use in ER25-compatible collet chucks on CNC machining centers, milling machines, and drilling equipment. This collet accommodates a 14 mm tool shank diameter and delivers a clamping pressure rating of 1800, providing secure tool retention during high-speed cutting operations. With an overall length of 1.338 inches and an overall diameter of 1.023 inches, the ERS25-0551 fits standard ER25 chuck bodies and is the correct choice when tooling consistency and runout control are critical to the job.

This ER25 collet is suited for precision metal cutting applications in both production shop and job shop environments. It is commonly installed in ER25 collet chucks mounted on vertical machining centers, horizontal mills, and drill presses wherever 14 mm round-shank tooling is used. Machinists, tool-and-die technicians, and CNC setup personnel are the typical end users. The ER25 series is a widely adopted standard across general metalworking and light aerospace work.

Key Features

Compatibility

Designed as a direct-fit replacement for ER25-compatible collet chucks accepting 14 mm tool shank diameters. Verify chuck series and collet bore size before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is powered down before changing collets. Clean the collet chuck bore and the collet seating surface before insertion to prevent runout caused by chips or contamination. Use the appropriate ER25 spanner wrench and torque the retention nut to the chuck manufacturer's specification.
