Parlec ER25-S015 ER25 Collet Set 15 Piece

Product Description

The PARLEC ER25-S015 is a 15-piece collet set built around the ER25 collet system, one of the most widely used toolholding standards in CNC machining. The set covers a clamping range of 1 mm through 16 mm in 1 mm increments, giving machinists a complete working range for standard end mills, drills, reamers, and other round-shank cutting tools. Each collet in the set conforms to the ER25 taper geometry and is designed for use in ER25-compatible chucks mounted in machining centers, CNC mills, and multi-axis turning centers. The set weighs 3.18 pounds and is packaged as a single kit.

This set is suited for production and job-shop environments where operators need to cover a broad range of tool shank diameters without sourcing individual collets. The 1 mm increment spacing makes the set appropriate for shops running both inch and metric tooling, since metric shank sizes from 1 mm through 16 mm are fully covered. Typical users include CNC machinists, toolroom technicians, and manufacturing maintenance personnel who require a complete ER25 collet assortment for quick tool changes and reduced setup time.

Compatibility

Designed for use in ER25-compatible chucks and toolholding systems. The ER collet standard is an internationally recognized toolholding geometry; confirm that the chuck or toolholder in use is rated for the ER25 taper before installation.

Installation Notes

ER collets are installed and removed by a licensed machinist or qualified toolroom technician using the appropriate ER25 collet nut and spanner wrench. De-energize and lock out the machine spindle before changing collets. Inspect each collet for wear, cracks, or deformation prior to use, and verify that the tool shank diameter does not exceed the collet's rated clamping range. Follow the machine tool manufacturer's torque and runout specifications for the chuck assembly.
