It carries grade 4340 with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance across a range of cutting conditions. The insert measures 0.5276 inches inscribed circle diameter and 0.1563 inches thick, with a 1.50 mm corner radius and a positive 5-degree rake angle. It features four cutting edges and a PH chip breaker geometry. Licensed machinists and CNC machine operators use this insert in production environments on steel, stainless steel, and cast iron workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is suited for applications involving steel, stainless steel, and cast iron, covering ISO material codes P, M, and K with material grades P40, M40, and K40. It handles a maximum depth of cut of 6.50 mm (0.2559 inches), making it appropriate for moderate to semi-heavy face milling passes. The insert is held by screw and fits right-hand cutter bodies in the R245 series. It is applicable to both production shop floor use and contract machining environments where consistent chip control and coating durability are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for extended tool life on ferrous materials\u003c\/li\u003e\n\u003cli\u003eGrade 4340 solid carbide with positive rake geometry for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for cost efficiency\u003c\/li\u003e\n\u003cli\u003ePH chip breaker for controlled chip formation on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 6.50 mm for productive face milling passes\u003c\/li\u003e\n\u003cli\u003eScrew-lock insert holding method for secure seating in R245 cutter bodies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with R245 series cutter bodies.

Always power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key for the clamping screw and ensure the insert seat is clean and free of chips before seating the new insert. Handle solid carbide inserts with care to avoid chipping the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4340\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\u003eInsert Size Code\u003c\/strong\u003e: 12T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5276 inches (13.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches (3.97 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0591 inches (1.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2559 inches (6.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P40, M40, K40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R245\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R245-12 T3 M-PH 4340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R245-12 T3 M-PH 4340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7564438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727623586098,"sku":"7564438","price":288.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8760a394a333def66300d119e044fab.jpg?v=1788680177","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7564438-milling-insert-grade-4340-r245","provider":"Voomi Supply","version":"1.0","type":"link"}
