Parlec ER25-0630 ER25 Collet 0.6299 Inches 16mm

Product Description

The PARLEC ER25-0630 is an ER25 series collet designed for use in ER25-compatible toolholders and collet chucks. It accepts workpieces and cutting tools up to 0.6299 inches (16.00 mm) in diameter, with a minimum collet capacity of 0.5906 inches (15.0 mm). The overall length is 1.338 inches. This collet is used in CNC machining centers, milling machines, and drilling applications where precise tool clamping is required. Machinists and toolroom professionals install and change these collets as part of routine toolholding setup.

The ER25-0630 fits any machine spindle or toolholder designed around the ER25 collet standard. It is suited for both light and moderate cutting operations across a range of materials. The 16.00 mm nominal size makes it a commonly stocked collet for shops running metric tooling on ER25 chucks. It is appropriate for production and maintenance machining environments in manufacturing facilities.

Installation Notes

ER collets are installed and removed by machinists using an appropriate ER25 collet nut and spanner wrench. Always power down and lock out the machine spindle before changing collets. Inspect the collet bore and seating taper for debris or damage before installation. Do not exceed the collet capacity range, as over-clamping outside the rated capacity range reduces clamping accuracy and can damage the collet.
