Accupro 588220 ER32 Collet 0.747 Inches

Product Description

The ACCUPRO 588220 is an ER32 series collet used to hold cutting tools and workpieces in CNC machining centers, milling machines, and lathes equipped with ER32 collet chucks. It accepts a decimal inch size of 0.747 inches with a minimum collet capacity of 0.719 inches, providing a secure clamping range suitable for a variety of shank diameters. Machinists and tool room technicians install this collet when setting up precision cutting operations that require repeatable tool runout and consistent grip force. The collet weighs 0.8 pounds and is sized for the standard ER32 specification.

This collet is intended for use in ER32-compatible toolholders found in production machining, job shop, and maintenance environments. It fits standard ER32 chucks used across a wide range of vertical and horizontal machining centers. Typical applications include end mill holding, drill chuck setups, and reaming operations where a 0.747-inch nominal shank diameter tool is required. Installation is straightforward and does not require specialized equipment beyond the appropriate ER32 chuck and spanner wrench.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Before installing or removing the collet, ensure the machine spindle is fully stopped and all power is off or the machine is in a locked-out state per applicable lockout/tagout procedures. Use the correct ER32 spanner wrench and collet nut to seat the collet properly in the chuck body. Do not exceed the manufacturer-rated clamping torque for the chuck, and inspect the collet for wear or damage before each use.
