Originally titled 'Shoulder Mill for Steel, Stainless Steel and Cast Iron'
Tangentially mounted for high cutting-edge strength, Sumitomo Electric Carbide’s PWS shoulder milling cutter series is designed to handle a variety of materials, including steel and cast iron. It is available in both coarse- and fine-pitch diameters ranging from 80 to 250 mm.
The shoulder mill features a two-step insert array structure that responds to deep cutting requirements, while breakers are optimized for edge sharpness and cutting ability. A17-mm insert is said to enable exceptional material removal, and its serrated design, created with high-precision molding technology, provides stable milling, even in large overhang applications.
