Sandvik Coromant 7611778 Ball End Mill Head 20mm E20

Product Description

The SANDVIK COROMANT 7611778 is a solid carbide ball end mill head designed for use with the CoroMill 316 modular milling system. With a 20mm (0.7874 inch) mill diameter and a 4-flute spiral configuration, this head delivers efficient material removal in contour milling, profiling, and finishing operations on hardened and difficult-to-machine materials. The AlTiN finish coating provides thermal resistance and extended tool life under high-speed cutting conditions. The right-hand cutting direction and 40-degree helix angle promote smooth chip evacuation. Connection is via E20 interface, compatible with CoroMill 316 modular bodies.

This ball end mill head is suited for use in CNC machining centers in both shop and production environments. It handles contour milling, die and mold work, and complex 3D surface finishing on ferrous and non-ferrous materials. The modular E20 connection allows fast head changes without removing the tool body from the spindle, making it practical for shops running multiple profiles on the same setup.

Key Features

• 20mm ball end diameter for contour and profile milling
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature performance and extended tool life
• 4-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Right-hand cutting and flute direction
• E20 modular connection for use with CoroMill 316 tooling system

Compatibility

Designed for use with the SANDVIK COROMANT CoroMill 316 modular milling system via E20 connection interface.

Installation Notes

Installation and setup should be performed by a qualified CNC machinist or tooling technician. Ensure the tool body and connection interface are clean and free of chips or debris before threading on the head. Follow the torque and clamping procedures specified in the CoroMill 316 system documentation for the E20 connection. Verify spindle direction and programmed feed rates match the right-hand cutting configuration before running the first pass.
