Accupro 588358 ER25 Collet 16 Mm

Product Description

The ACCUPRO 588358 is an ER25 series collet designed to hold 16 mm shank tooling in compatible collet chucks. ER collets are the industry-standard clamping solution for CNC machining centers, milling machines, and lathes, providing reliable concentricity and clamping force across a range of cutting tools. This collet is built to the ER25 specification, which defines the taper angle, outer diameter, and clamping range. It is sized for 16 mm tool shanks and rated to 1000 units of clamping pressure as specified. Machinists and toolroom technicians install ER collets during tool changes and setup operations.

This collet is used in machine shop environments wherever ER25-compatible collet chucks are installed. Typical applications include end mill holding, drill chuck replacement, and reamer or tap holding on CNC machining centers and manual mills. The ER25 series is common in light to medium-duty machining operations in both production and job-shop settings. The 16 mm size accommodates metric shank tooling within its specified clamping range.

Compatibility

Designed for use with ER25-series collet chucks and tool holders that accept the standard ER25 taper specification. Specific machine or chuck model compatibility was not provided in the available product data.

Installation Notes

ER collets are installed and removed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before changing collets. Inspect the collet bore, seating taper, and retaining nut threads for wear or debris before installation. Do not exceed the collet clamping range, as under- or over-sized shanks can cause runout or tool pull-out during cutting.
