It carries a CVD-applied tri-layer coating of TiCN, Al2O3, and TiN under the manufacturer grade designation 3330. The square insert shape features four cutting edges with a positive rake angle of 6 degrees and a corner radius of 0.0591 inches (1.50 mm), making it suited for consistent, repeatable stock removal in cast iron applications. The inscribed circle measures 0.5276 inches (13.40 mm) and the insert thickness is 0.1563 inches (3.97 mm). Insert holding is by screw, and the cutting edge style is corner rounded with a KM chip breaker geometry.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in face milling operations on cast iron workpieces, classified under primary workpiece material code K. It fits the R245 cutter series and is identified by catalog number R245-12 T3 M-KM 3330. The maximum depth of cut is 0.2559 inches (6.50 mm), keeping it well-suited for moderate finishing and semi-finishing passes on cast iron components. It is a single-sided, right-hand insert sold individually with a minimum order quantity of 10 units. The insert is conformant to both ANSI and ISO standards under code R245-12 T3 M-KM 3330.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD tri-layer coating: TiCN, Al2O3, and TiN for wear resistance in cast iron cutting\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for extended tool life per unit cost\u003c\/li\u003e\n  \u003cli\u003ePositive 6-degree rake angle reduces cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003eKM chip breaker geometry engineered for cast iron chip control\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0591 inches (1.50 mm) for controlled edge strength\u003c\/li\u003e\n  \u003cli\u003eScrew-held single-sided design for secure seating in R245 cutter pockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in R245 series milling cutter bodies as specified by the manufacturer catalog number R245-12 T3 M-KM 3330.
