Decoding the MPN: \"745R\" identifies the CoroMill 745 right-hand insert family; \"21\" denotes the inscribed circle size (21 mm); \"09\" specifies the insert thickness (9 mm); \"E\" indicates the chipbreaker geometry (positive, light-cutting M50 geometry suited for general-purpose and finishing operations); \"M50\" is the Sandvik geometry designation optimized for medium to finishing cuts across P and K material groups (steels and cast irons); \"4230\" is the Sandvik carbide grade — a CVD-coated cemented carbide (MT-TiCN\/Al₂O₃ multilayer coating) engineered for high wear resistance and thermal stability in milling of steel and cast iron. Each insert features 14 usable cutting edges (numbered 1–14 as visible on the face), maximizing economy per insert. The golden CVD coating is clearly visible in the photos. This pack contains 10 inserts in the original Sandvik Coromant black plastic tray with factory seal intact. Compatible with Sandvik CoroMill 745 face milling cutters; refer to Sandvik Coromant toolholder selection guides for cutter body pairing.\u003c\/p\u003e\n\u003ch3
