Sandvik Coromant 7611809 Square End Mill Head 25mm

Product Description

The SANDVIK COROMANT 7611809 is a solid carbide square end mill head designed for high-performance milling operations in demanding machining environments. Part of the CoroMill 316 series, this head features a 25.00 mm (0.9843 inch) cutting diameter, an 8-flute configuration, and a 45-degree helix angle that promotes smooth chip evacuation and reduces cutting forces. The AlTiN finish coating enhances heat resistance and wear life, making this head well-suited for dry or near-dry cutting of hardened steels, cast iron, and high-temperature alloys. It connects via the E25 interface for secure, repeatable mounting on compatible CoroMill 316 tooling systems. Installation and setup are typically performed by CNC machinists and tool crib technicians.

This end mill head is intended for use in CNC machining centers where modular tooling systems are employed. The CoroMill 316 platform allows quick head changes without disturbing the setup, reducing downtime in production environments. With a length of cut of 13.50 mm and an overall length of 13.50 mm, the 7611809 is configured for shorter-reach, high-stability applications such as shoulder milling, slot milling, and pocket milling in ferrous and exotic materials. The right-hand cutting and right-hand flute direction are standard for conventional spindle rotation on most CNC machining centers.

Key Features

• 25.00 mm cutting diameter with 0.9843 inch decimal equivalent for cross-reference convenience
• 8-flute geometry supports higher feed rates and improved surface finish in finishing passes
• 45-degree helix angle reduces axial cutting forces and improves chip flow
• AlTiN coating provides thermal resistance and extended tool life in abrasive materials
• E25 modular connection enables precise, repeatable head indexing on CoroMill 316 bodies
• Center cutting capable, allowing direct plunge or ramping entry into workpieces

Compatibility

Designed for use with SANDVIK COROMANT CoroMill 316 modular end mill bodies equipped with the E25 connection interface.

Installation Notes

Mounting and tool changes should be performed with the machine spindle fully stopped and the control in a safe state per shop lockout/tagout procedures. Use the manufacturer-specified torque tool for the E25 connection to ensure proper seating — do not use improvised tools that could damage the interface threads or seating surfaces. Verify runout with a dial indicator after mounting before commencing cuts. Handle solid carbide tooling carefully to avoid chipping the cutting edges.
