Accupro 587368 ER32 Collet 0.393 Inch 10.00mm

Product Description

The ACCUPRO 587368 is an ER32 precision collet designed to hold cutting tools and workpieces in CNC machining centers, milling machines, and lathes equipped with ER32-compatible tool holders. This collet accepts a nominal bore size of 0.393 inches (10.00mm) with a minimum collet capacity of 0.354 inches (9.0mm), providing a clamping range suited to a variety of shank diameters. It achieves a total indicator runout (TIR) of 0.01mm, delivering the concentricity required for precision material removal in both production and job-shop environments. Machinists, toolroom technicians, and CNC operators use this collet as a direct replacement or spare in high-rotation ER32 tooling setups.

This collet is appropriate for use in standard ER32 collet chucks across vertical machining centers, horizontal mills, and CNC turning applications. It is suited to both light-duty finishing passes and moderate stock-removal operations where consistent tool runout is critical to part quality. The 0.01mm TIR specification makes it a reliable choice for shops holding tight positional tolerances on milled or turned features. It is sold individually, making it practical for single-position replacement without requiring a full set purchase.

Compatibility

Designed for use with ER32-series collet chucks and tool holders conforming to the DIN 6499 standard for ER-style collets.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before installing or removing the collet, confirm the spindle is fully stopped and the machine is in an energy-isolated state per your facility lockout/tagout procedure. Seat the collet into the collet nut before threading onto the holder, and tighten to the tool holder manufacturer's specified torque using an appropriate ER collet wrench. Inspect the collet bore and seating surfaces for chips or contamination prior to assembly, as debris will directly affect runout performance.
