Accupro 588894 ER25 Collet 0.622 Inch

Product Description

The ACCUPRO 588894 is an ER25 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment that accepts ER25 toolholding systems. This collet holds cutting tools and workholding devices with a maximum capacity of 0.622 inches and a minimum collet capacity of 0.593 inches, providing a secure grip across that clamping range. Weighing 0.7 pounds, it is a single-piece unit sold individually. Machinists and tool-and-die professionals rely on ER-series collets for consistent tool runout control and repeatable setups in precision machining operations.

The 588894 is suited for use in production and job-shop environments where ER25-compatible collet chucks are installed. It is appropriate for holding end mills, drills, reamers, and similar shank-type cutting tools within its stated capacity range. The collet fits any spindle or chuck designed to the ER25 standard, making it a widely applicable toolholding component in both manual and CNC machining setups.

Compatibility

Designed as a direct-fit replacement or supplemental collet for any toolholder or collet chuck manufactured to the ER25 standard. Refer to your spindle or chuck manufacturer specifications to confirm ER25 collet compatibility before installation.

Installation Notes

ER collets are installed by qualified machinists or tool room personnel. Before changing collets, ensure the machine spindle is fully stopped, the control is in E-stop or locked out, and power is isolated per your facility lockout/tagout procedure. Insert the collet into the ER25 collet nut before seating in the chuck body, and torque the nut to the chuck manufacturer specifications using a proper spanner wrench. Do not exceed the stated maximum collet capacity, as oversized tooling will damage the collet and reduce clamping force.
