Sandvik Coromant 5739907 Square-shoulder Face Mill

Product Description

The SANDVIK COROMANT 5739907 is an indexable square-shoulder face mill from the CoroMill 210 series, designed for precision milling operations in metalworking and machining environments. It accepts four R210-090412M inserts held by clamp and screw, and features through-coolant capability to manage heat at the cutting zone. The cutter has a maximum cutting diameter of 36.7mm (1.4449 inches), a maximum depth of cut of 1.2mm (0.0472 inches), and a 10-degree lead angle with a positive rake geometry. The arbor hole diameter is 3/4 inch (19.05mm). This tool is installed and operated by machinists and CNC programmers working in close-pitch milling applications.

The 5739907 is suited for square-shoulder milling operations on a variety of workpiece materials where close-pitch insert arrangement and positive rake geometry are specified. The right-hand cutting direction and through-coolant design make it appropriate for use on CNC machining centers and manual mills equipped with coolant-through spindles or arbors. It is commonly used in production environments requiring consistent shoulder geometry and repeatable insert indexing.
