Parlec ER25-0500 ER25 Collet 0.5 Inch

Product Description

The PARLEC ER25-0500 is an ER25-series collet designed to hold round shank tooling at a nominal bore size of 0.5 inches (1/2 inch). It features an overall length of 1.338 inches and an overall diameter of 1.023 inches, making it a compact, precision clamping component for use in ER25-compatible collet chucks. The minimum collet capacity is 0.461 inches. Machinists and CNC setup technicians install this collet in milling, drilling, and tapping applications where consistent, repeatable tool holding is required.

This collet is used in machining centers, CNC mills, and manual milling machines equipped with ER25 collet chuck systems. It is suited for production and job-shop environments where a 1/2-inch shank end mill, drill, or tap needs to be secured reliably. The compact overall length allows use in tight-clearance setups without sacrificing gripping strength.

Key Features

• 0.5 inch nominal bore accommodates 1/2-inch shank tooling
• Minimum collet capacity of 0.461 inches for a wide clamping range
• Overall length of 1.338 inches supports close-clearance machining setups
• Overall diameter of 1.023 inches consistent with ER25 envelope dimensions

Compatibility

Designed as an OEM-style replacement or standard-fit collet for ER25 collet chucks accepting 1/2-inch shank tooling.

Installation Notes

Installation is performed by qualified machinists or CNC technicians. Always ensure the spindle is fully stopped and the machine is in a locked-out, de-energized state before changing collets. Clean the collet chuck bore and collet taper surfaces before seating the collet to ensure proper runout performance. Do not exceed the rated clamping range when inserting tool shanks, as over-clamping or under-clamping can lead to tool pullout or collet damage.
