Parlec ERS25-0590 ER25 Collet 15mm Bore

Product Description

The PARLEC ERS25-0590 is an ER25 series collet designed for use in ER25-compatible toolholders and collet chucks. It accepts a 15 mm bore diameter and has an overall length of 1.338 inches with an overall diameter of 1.023 inches. This collet is used to secure round-shank cutting tools such as end mills, drills, and reamers in CNC machining centers, milling machines, and lathes. Machinists and toolroom technicians install this collet as part of a precision workholding or tool-holding assembly where repeatable runout and consistent clamping force are required.

The ERS25-0590 is suited for general-purpose machining operations in job shop, production, and toolroom environments. It fits within the ER25 collet standard, which is one of the most widely used collet systems in CNC and manual machine tool applications. The 15 mm bore size accommodates tooling with a 15 mm shank diameter. It is a direct-fit collet intended for any ER25-series collet chuck or toolholder that accepts the ER25 standard.

Installation Notes

Installation is performed by a machinist or toolroom technician. De-energize and lock out the machine spindle before inserting or removing any collet. Seat the collet into the ER25 collet nut before threading the nut onto the toolholder, and tighten using an appropriate ER collet wrench to the toolholder manufacturer's torque specification. Inspect the collet bore and seating surface for chips or debris before each use to maintain clamping accuracy and runout performance.
