Accupro 588363 Sealed Er Coolant Collet ER32 5mm

Product Description

The ACCUPRO 588363 is a sealed ER coolant collet in the ER32 series, sized at 5 mm. Sealed ER coolant collets direct cutting fluid through the collet body to the cutting tool tip, improving chip evacuation and tool life in high-speed machining operations. This collet is designed for use in ER32 collet chucks mounted on CNC machining centers, milling machines, and drilling equipment. It weighs 0.8 pounds and fits within the standard ER32 collet envelope. Machinists and CNC operators install this collet when through-spindle or through-chuck coolant delivery is required for precision cutting applications.

This sealed ER coolant collet is suited for shops running through-coolant tooling in ER32-compatible tool holders. The sealed design prevents coolant from bypassing the collet bore, ensuring consistent coolant pressure reaches the tool tip. Typical applications include deep-hole drilling, reaming, and finish milling where heat and chip buildup at the cutting edge must be managed. The 5 mm bore accommodates shanks at that diameter in production and job-shop environments.

Key Features

• Sealed collet body channels coolant directly to the cutting tool tip
• ER32 series — fits standard ER32 collet chucks
• 5 mm bore size for compatible shank tooling
• Supports through-spindle and through-chuck coolant delivery systems
• UNSPSC Code 27112800 for procurement system compatibility

Compatibility

Designed as an OEM-style replacement or standard fitment for ER32-series collet chucks used in CNC milling, drilling, and turning applications requiring sealed coolant delivery.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before removing or installing any collet. Clean the collet chuck bore and collet taper surfaces before seating the collet to ensure proper clamping force and runout. Verify that the tool holder and drawbar torque are set according to the machine tool manufacturer specifications before operation.
