Accupro 588884 ER25 Collet 0.31 Inch

Product Description

The ACCUPRO 588884 is an ER25 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment. It accepts round shank tooling with a decimal inch size of 0.31 inches and a minimum collet capacity of 0.281 inches. The ER25 collet standard is one of the most widely used clamping systems in precision machining, offering reliable tool holding through a threaded collet nut and tapered bore. This collet is suited for machinists and tool-room technicians working with compatible ER25 collet chucks in production or maintenance environments.

The ACCUPRO 588884 is used in applications where consistent, repeatable tool clamping is required across turning, drilling, and milling operations. Its 0.31-inch capacity makes it appropriate for holding end mills, drills, reamers, and other standard round-shank tools within that size range. It is typically found in light to medium-duty CNC and manual machining setups in both job shop and production facility environments.

Compatibility

Designed as a standard ER25-series collet for use with ER25 collet chuck holders conforming to the ER25 collet standard. Verify chuck compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the collet. Clean the collet bore and chuck taper before seating the collet to prevent runout. Do not overtighten the collet nut beyond the chuck manufacturer's specified procedure.
