Sandvik Coromant 6289911 Square-shoulder Face Mill

Product Description

The SANDVIK COROMANT 6289911 is an indexable square-shoulder face mill designed for precision milling operations in metal-cutting applications. Part of the CoroMill 419 series, it accepts five 419R-1405 style inserts and features through-coolant capability for extended tool life and improved chip evacuation at the cutting zone. The cutter delivers a maximum cutting diameter of 61.5 mm (2.42 inches) with a maximum depth of cut of 2 mm (0.079 inches). A 19-degree lead angle and positive rake geometry reduce cutting forces and support stable, efficient material removal. This tool is mounted via a 1-inch arbor hole and is suited for close-pitch finishing and semi-finishing passes on steel and similar workpieces.

The 6289911 face mill is intended for use in machining centers and milling machines where square-shoulder profiles and tight tolerances are required. Its close-pitch insert arrangement and right-hand cutting direction make it well-suited for light to medium axial engagements in production environments. Licensed machinists, tooling specialists, and CNC operators handling ferrous and non-ferrous materials will find this cutter appropriate for face milling, shoulder milling, and step-milling operations. Through-coolant delivery supports high-speed runs where heat management is critical.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or indexing inserts. Seat the arbor securely and verify insert clamp torque per the toolholder manufacturer's documentation. Confirm through-coolant port alignment with the machine spindle coolant supply before operation.
