It features an octagon shape with 16 cutting edges and a double-sided design, maximizing tool life and reducing per-edge cost. The insert is CVD-coated with a Duratomic TiCN and Al2O3 multilayer coating for thermal resistance and wear performance. At 4.00 mm thick with a 12.00 mm inscribed circle and a negative rake geometry with 20-degree rake angle, it is engineered for productive milling in steel and other demanding workpiece materials. A T-Land cutting edge style and M11 chip breaker geometry support stable chip formation at a range of feed rates.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling operations on steel as its primary workpiece material, with rated secondary applications in stainless steel, cast iron, superalloys, and titanium. It carries ISO material codes P, M, K, and S, covering a broad spectrum of metalcutting scenarios. Typical applications include face milling, shoulder milling, and high-feed milling on machining centers where consistent chip control and edge durability are priorities. The neutral hand orientation allows flexible mounting in compatible tooling systems. It is installed by machinists and tooling technicians in production, job shop, and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e16 cutting edges on a double-sided octagon insert for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003eCVD Duratomic TiCN and Al2O3 coating for high thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eMP2501 grade with fine grain carbide substrate for toughness and wear balance\u003c\/li\u003e\n\u003cli\u003eM11 chip breaker geometry engineered for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eNegative rake with T-Land cutting edge for stable, predictable cutting action\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting method for secure and repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eCompatible with R217.48-05 and R220.48-05 cutter series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SECO cutter series R217.48-05 and R220.48-05.
