Sandvik Coromant has expanded its offering of CoroMill 210, the milling cutter with the capability for both productive plunge milling and high feed-face milling. Now cutter diameters up to approximately 4 inches are being introduced. Combining two different operations is made possible through the design of the cutter body, insert seat and the inserts themselves. A 10-degree entering angle allows extreme feed rates at small axial depths of cut when the tool is fed tangentially - and also high radial depths of cut when fed axially in roughing operations.
