Sandvik Coromant 7611851 Square End Mill Head 4 Flute

Product Description

The SANDVIK COROMANT 7611851 is a solid carbide square end mill head designed for precision milling operations in metalworking and machining applications. This head features a 1/2 inch mill diameter with a 0.315 inch length of cut and a 0.315 inch overall length. It uses an E12 connection interface for mounting to compatible CoroMill 316 series adaptors. The 4-flute geometry with a 50-degree helix angle promotes smooth chip evacuation and stable cutting action. An AlTiN finish coating improves heat resistance and extends tool life in demanding cutting conditions. Licensed machinists and CNC operators install this component as part of a modular tooling setup.

This end mill head is suited for use in CNC machining centers performing slotting, profiling, and finishing passes on ferrous and non-ferrous metals. Its compact overall length of 0.315 inches makes it appropriate for applications where reach is limited and rigidity is a priority. The center-cutting geometry allows plunge entry. It belongs to the CoroMill 316 series, which is a modular milling system that pairs dedicated heads with precision adaptors to reduce tooling inventory while maintaining dimensional accuracy across setups.

Compatibility

Designed for use with the SANDVIK COROMANT CoroMill 316 modular milling system via the E12 connection interface. Compatible adaptors must accept the E12 head connection standard.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the tool path program must be cleared before changing heads. Use the torque specifications provided by SANDVIK COROMANT for the E12 connection interface in the official CoroMill 316 product documentation. Inspect the connection seat for chips or contamination before seating the head to ensure proper runout.
