Sandvik Coromant 5738657 Square-shoulder Face Mill

Product Description

The SANDVIK COROMANT 5738657 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining environments. Part of the CoroMill 245 series, this cutter accommodates three R245-12T3.. inserts secured by clamp and screw, delivering a maximum cutting diameter of 1.25 inches and a maximum depth of cut of 0.24 inches (6.10 mm). With a 45-degree lead angle and positive rake geometry, it is engineered for right-hand cutting direction. Machining professionals and CNC operators use this tool in milling applications requiring reliable square-shoulder performance and consistent chip evacuation.

This face mill is suited for close-pitch milling on CNC machining centers and milling machines handling ferrous and non-ferrous materials. Its 1-inch arbor hole diameter and 3.86-inch overall height make it a compact option for small-diameter face milling operations. The Cutter Style RA245 designation fits into the broader CoroMill 245 platform, which targets high-productivity shoulder milling. It is installed and used by machinists and tooling specialists working in job shops, production machining facilities, and aerospace or general metalworking environments.
