Sandvik Coromant 5739741 Indexable Face Mill Coromill 245

Product Description

The SANDVIK COROMANT 5739741 is an indexable chamfer angle face mill from the CoroMill 245 series, designed for right-hand face milling operations on machining centers and milling machines. It accepts five R245-18T6 series inserts and delivers a maximum depth of cut of 0.3937 inches. The steel toolholder spans a minimum cutting diameter of 3 inches and a maximum cutting diameter of 3.74 inches, with a 1-inch arbor hole for secure spindle mounting. This cutter is built for production environments where consistent face milling, chamfering, and shoulder work are required across ferrous and non-ferrous workpieces.

The 5739741 face mill fits typical horizontal and vertical machining center setups requiring a mid-range diameter cutter with a 45-degree chamfer geometry. It is well suited for roughing and semi-finishing passes on flat surfaces and step features. The 1-inch arbor hole accepts standard arbor and adapter systems commonly found in production shops and toolrooms. A maximum spindle speed of 6,300 RPM supports both moderate and higher-feed strategies depending on insert grade selection. This tool is installed and set up by machinists and CNC tooling technicians.
