Accupro 587371 ER32 Collet 0.511 Inch

Product Description

The ACCUPRO 587371 is an ER32 series collet designed for precision tool holding in CNC machining and manual milling applications. It accepts a nominal collet size of 0.511 inches (13.00mm) and delivers a total indicated runout (TIR) of 0.01mm, making it suited for work where concentricity and repeatability are critical. The collet clamps cutting tools, drill bits, or end mills into ER32-compatible collet chucks. Machinists and CNC operators rely on ER-series collets as the standard for versatile, high-precision tool holding across a wide range of shop environments.

This collet is appropriate for use in machine shops, production facilities, and toolroom environments running ER32 collet chucks on CNC machining centers, mills, lathes, and similar equipment. The ER32 series is one of the most widely adopted collet standards, making this collet a common replacement or addition to existing toolholding setups. The minimum collet capacity is 0.472 inches (12.0mm), giving it a clamping range suited for tools within that span.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Before changing tooling, ensure the spindle is fully stopped and the machine is in a safe, locked-out state per shop safety procedures. Use a properly rated ER32 collet nut and torque wrench rated for the chuck specification to seat the collet correctly. Inspect the collet bore and chuck taper for debris or damage before installation to maintain rated TIR performance.
