Parlec ER25-0315 ER25 Collet 0.315 Inch 8mm

Product Description

The PARLEC ER25-0315 is an ER25 series collet designed for use in CNC machining centers, milling machines, and other spindle-driven equipment that accept the ER25 collet standard. It holds workpieces or cutting tools with a nominal collet size of 0.315 inches (8.00 mm) and a minimum collet capacity of 0.2756 inches (7.0 mm). Overall length is 1.338 inches. The ER25-0315 is installed by machinists and toolroom technicians where repeatable, concentric tool holding is required in precision cutting operations.

This collet fits standard ER25 collet chucks and toolholders used in production and job-shop machining environments. It is suited for light to moderate milling, drilling, reaming, and tapping operations where a secure grip on shanks up to 0.315 inches is needed. The ER series is one of the most widely adopted collet standards in CNC and manual machining, making this collet a common replacement or additional-capacity item in toolroom inventory.

Installation Notes

Installation is performed by a machinist or toolroom technician. Always power down and lock out the machine spindle before changing collets. Seat the collet fully in the nut before inserting it into the chuck body, and torque the retaining nut according to the chuck manufacturer specifications. Inspect collet seating surfaces for chips or wear before each use to maintain runout tolerances.
