Sandvik Coromant 5739861 Square-shoulder Face Mill

Product Description

The SANDVIK COROMANT 5739861 is an indexable square-shoulder face mill from the CoroMill 210 series, designed for precision milling in metal-cutting operations. With a maximum cutting diameter of 52.2mm (2.0551 inches) and a 1-inch arbor hole, this right-hand cutter accommodates 6 inserts using the R210-140512M insert style. The maximum depth of cut is 2mm (0.0787 inches), making it suited for finishing and light shoulder-milling passes. Through-coolant capability supports extended insert life and chip evacuation at the cutting zone. Installation and operation are handled by machinists and CNC tooling technicians in precision machining environments.

The 5739861 is built for square-shoulder milling applications in both production and job-shop settings. Its 10-degree lead angle and 6-flute configuration support controlled chip load across a range of workpiece materials. The Cutter Style RA210 body, standing 50.01mm (1.969 inches) tall, fits arbor-mounted setups on vertical and horizontal machining centers. Through-coolant compatibility makes it well-suited for applications where heat management and chip control are critical, including ferrous and non-ferrous material removal.
