Accupro 588373 ER32 Sealed Coolant Collet 15 Mm

Product Description

The ACCUPRO 588373 is a sealed ER coolant collet designed for use with ER32 collet chucks on CNC machining centers and manual milling machines. This collet accepts tooling with a 15 mm shank diameter and features an internal seal that directs coolant flow through the tool, improving chip evacuation and extending tool life during high-speed drilling, reaming, and milling operations. It is installed by machinists and CNC setup technicians as part of a precision workholding assembly. The sealed design keeps coolant directed axially rather than allowing it to escape at the collet-to-chuck interface.

This collet is suited for production machining environments where through-spindle or through-chuck coolant delivery is required. Typical applications include high-volume drilling and deep-pocket milling where thermal management and chip clearing at the cutting zone are critical. The ER32 series is widely used in both job shop and production floor settings across aerospace, automotive, and general metalworking industries.

Key Features

• Sealed collet design directs coolant through the tool for effective chip evacuation
• ER32 collet series for broad compatibility with standard ER32 chucks
• 15 mm collet size accommodates 15 mm shank cutting tools
• Designed for use in CNC machining centers and milling machines with coolant-through capability
• UNSPSC Code 27112800 for streamlined procurement classification

Compatibility

Designed as an OEM-style replacement or upgrade collet for use with standard ER32 collet chucks equipped with coolant-through capability.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Before installing or removing the collet, ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state. Insert the collet into the ER32 chuck before placing the tool shank, then tighten the chuck nut to the chuck manufacturer's specified procedure using an appropriate ER collet wrench. Verify coolant passages are clear and the seal is properly seated before resuming coolant flow.
