Sandvik Coromant 7611887 Ball End Mill Head 1in 4FL Altin

Product Description

The SANDVIK COROMANT 7611887 is a solid carbide ball end mill head designed for high-performance milling operations in demanding machining environments. Part of the CoroMill 316 series, this replaceable head connects via an E25 interface, allowing quick changeovers on compatible modular tooling systems. The 1.0000 inch mill diameter, 40-degree helix angle, and 4-flute spiral geometry produce efficient chip evacuation and smooth surface finishes on ferrous and hardened materials. An AlTiN finish coating extends tool life at elevated cutting temperatures. Licensed machinists and CNC operators working in job shops, aerospace, die and mold, and general precision machining will find this head well-suited to their applications.

The 7611887 is intended for use on modular milling systems with an E25 connection, such as those found on vertical and horizontal machining centers. The right-hand cutting direction and right-hand flute orientation are standard for conventional CNC milling setups. With a 14.00 mm length of cut and 14.00 mm overall length, this head is configured for shorter reach, high-rigidity applications where minimizing overhang is critical to part accuracy and tool stability. It is packaged individually and sold as a single unit.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard material applications
• AlTiN coating provides heat resistance and extended tool life at high cutting speeds
• 40-degree helix angle promotes smooth cutting action and efficient chip flow
• 4-flute spiral geometry balances material removal rate with surface finish quality
• E25 modular connection enables fast head swaps without full tool disassembly
• Right-hand cut and flute direction compatible with standard CNC milling spindle rotation

Compatibility

Designed for use with CoroMill 316 series modular milling bodies and arbors equipped with an E25 connection interface.

Installation Notes

Installation and removal of replaceable milling heads should be performed by a qualified machinist following the tooling manufacturer's torque and clamping procedures for E25 modular connections. Power down and lock out the machine spindle before changing heads. Inspect the connection interface for chips, debris, or damage before seating the head. Verify runout with a dial indicator after assembly before beginning any cutting operation.
