Sandvik Coromant 5760511 ER25 Sealed Coolant Collet 5 Mm

Product Description

The SANDVIK COROMANT 5760511 is a sealed ER coolant collet designed for use in ER25 collet chucks on CNC machining centers and milling machines. The sealed design allows through-spindle or through-tool coolant delivery directly to the cutting zone, improving chip evacuation and tool life on demanding machining operations. This collet accepts a 5 mm tool shank and has an overall length of 34 mm. It is engineered to maintain concentricity and clamping force while sealing coolant pressure within the collet chuck body. Machinists and tooling technicians working in production environments install this collet as part of a precision toolholding assembly.

This collet is suited for use in high-pressure coolant applications where conventional open collets would allow coolant to bypass the tool shank. Typical install scenarios include vertical and horizontal machining centers running small-diameter drills, end mills, or reamers at 5 mm shank diameter. The ER25 series is a widely adopted collet standard in precision CNC toolholding, making this collet a direct fit for any ER25-compliant chuck body. It is commonly used in aerospace, automotive, and general precision machining shops where coolant-through tooling is required.

Key Features

• Sealed ER design enables through-tool coolant delivery to the cutting edge
• ER25 collet series for compatibility with standard ER25 chuck bodies
• 5 mm collet size accommodates small-diameter tooling
• 34 mm overall length suits standard ER25 chuck depth requirements
• Precision-ground construction supports accurate tool runout and clamping force

Compatibility

Designed for use with ER25-compliant sealed collet chucks that support through-coolant delivery. Compatible with any ER25 chuck body that accepts sealed coolant collets and requires a 5 mm tool shank bore.

Installation Notes

Installation is performed by tooling technicians or machinists as part of CNC toolholding setup. Ensure the spindle is fully stopped and the machine is in a safe state before changing collets. Clean the chuck body bore and collet seat before insertion to ensure proper seating and clamping force. Do not exceed the coolant pressure rating of the chuck body assembly when operating with through-coolant systems.
