Sumitomo presses all the right buttons

Five different grades of RDMT button-style indexable milling inserts for carbon, alloy, stainless steels and cast iron have been added to Sumitomo Electric Hardmetal’s milling portfolio. 

The new inserts span application advantages where benefits from high wear resistance to high resistance to insert fracturing are required. Available in sizes of 8, 10, 12 and 16mm inscribed circle, the five grades cover PVD coated ACP100, 200 and 300 and CVD coated ACK200 and 300.

The ACP100 for cutting steel and ACK200 grades for cast iron incorporate Sumitomo’s Super FF ultra-hard coating that employs a tough carbide substrate with an ultra-fine TiCN crystal structure.

The ACP200 and 300 grades for milling steel and ACK300 for cast iron employs Sumitomo’s Super ZX multi-layer nano technology coating which combines alternating 10 nanometre thin layers of TiAN and AlCrN.

The ACP200 is ideal for general milling applications of steel as well as die steels, while ACP300 is better for interrupted machining and is ideally applied for stainless steel processing. Meanwhile, ACK300 is specifically developed for general and interrupted milling of cast and ductile irons.
