Manufactured to grade 4330 and coated via CVD process with a TiCN, Al2O3, and TiN multilayer stack, this insert delivers wear resistance and thermal stability under sustained cutting loads. The square insert geometry features a 90-degree included angle, a positive 15-degree rake angle, and a corner radius of 1.50 mm (0.0591 inches) with a PL chip breaker. It is sized to the 12T3 insert size code with an inscribed circle of 13.40 mm (0.5276 inches) and a thickness of 3.97 mm (0.1563 inches). This insert is installed by CNC machinists and toolroom technicians working with indexable milling toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for primary workpiece materials in the P (steel) and K (cast iron) material grade classifications, covering ISO grades P30, M30, and K30. It fits the R245 cutter series and is identified by ANSI and ISO code R245-12 T3 M-PL 4330. Typical applications include shoulder milling, face milling, and general-purpose material removal where consistent chip control and edge life are required across medium to heavy cutting conditions. Maximum depth of cut is 6.50 mm (0.2559 inches). Right-hand cutting geometry applies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiCN, Al2O3, and TiN multilayer coating for elevated wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 4330 formulation suited for P30, M30, and K30 material classifications covering steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and PL chip breaker for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003ePositive 15-degree rake angle reduces cutting forces and is well-suited for light-to-medium feed applications\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert, single-sided, with screw-type insert holding method\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 6.50 mm (0.2559 inches) supports both finishing and semi-roughing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in the R245 cutter series toolholders.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer when seating the clamping screw — do not overtighten. Inspect the insert pocket and seating surfaces for debris or wear before installing a new insert to ensure proper contact and edge alignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R245\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 12T3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P30, M30, K30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.50 mm (0.0591 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 13.40 mm (0.5276 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.97 mm (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1614 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.50 mm (0.2559 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R245-12 T3 M-PL 4330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R245-12 T3 M-PL 4330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7564439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727112175922,"sku":"7564439","price":37.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d30a01e8eb74324a7dfac3fcaf51151.jpg?v=1788673544","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7564439-milling-insert-grade-4330-r245","provider":"Voomi Supply","version":"1.0","type":"link"}
