Accupro 588206 ER32 Collet 0.31 Inches

Product Description

The ACCUPRO 588206 is an ER32 series collet designed for use in CNC machining centers, milling machines, and other spindle-driven equipment that accepts ER32 toolholding systems. This collet holds workpieces or cutting tools with a nominal capacity of 0.31 inches and a minimum collet capacity of 0.281 inches. It is sized for precision toolholding applications where consistent clamping force and runout control are required. Machinists and CNC operators working in job shops, production facilities, or toolroom environments rely on ER-series collets as a standard, interchangeable method for securing end mills, drills, reamers, and similar cutting tools.

The 588206 collet is suited for use in any ER32-compatible collet chuck or toolholder. ER32 is one of the most widely adopted collet standards in machining, making this collet applicable across a broad range of machine tool brands and spindle configurations. It is appropriate for both roughing and finishing operations where secure tool retention and repeatable positioning are priorities. This collet ships individually and is intended for replacement or expansion of an existing ER32 toolholding setup.

Key Features

• ER32 collet series for broad compatibility with ER32-standard chucks and toolholders
• Nominal clamping diameter of 0.31 inches with a minimum capacity of 0.281 inches
• Rated clamping pressure of 300 psi for secure tool retention during cutting operations
• Weighs 0.8 pounds, typical of solid ER32 collet construction
• Single-piece packaging for individual replacement or tooling inventory expansion

Compatibility

Designed for use with ER32-standard collet chucks and toolholders. Any spindle or chuck manufactured to the ER32 collet specification will accept this collet.

Installation Notes

ER collets are installed and removed by a machinist or CNC operator using an ER32-compatible collet nut and spanner wrench. Before changing tooling, the machine spindle must be fully stopped and the machine placed in an appropriate safe state per shop lockout/tagout procedures. Do not exceed the collet's stated capacity range, as oversizing can damage the collet bore and reduce clamping accuracy. Inspect the collet and chuck bore for contamination or wear before each use to maintain runout tolerances.
