Sandvik Coromant 5739737 Square-shoulder Face Mill 3 in

Product Description

The SANDVIK COROMANT 5739737 is an indexable square-shoulder face mill from the CoroMill 245 series, designed for high-productivity milling of steel, cast iron, and other workpiece materials. It features a 3-inch maximum cutting diameter and accepts four R245-12T3 inserts secured by clamp and screw. The 45-degree lead angle and positive rake geometry reduce cutting forces and promote smooth chip evacuation. With a 1-inch arbor hole and 50 mm overall height, this cutter mounts to standard arbors and suits horizontal and vertical milling machines used by tooling specialists and machining professionals.

This face mill is suited for square-shoulder milling operations requiring a true 90-degree wall and floor finish. The CoroMill 245 platform is a widely used system in production and job-shop environments for profiling, face milling, and shoulder milling on machining centers and manual mills. Right-hand cutting direction supports conventional spindle setups. At 3 inches in cutting diameter, it fits mid-size machining operations where precision shoulder geometry and insert economy are priorities.
