Manufactured to grade 4220, it features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN that delivers thermal resistance and wear performance across a range of demanding cutting applications. The insert measures 18.00 mm inscribed circle diameter with a 6.10 mm thickness and a 1.00 mm corner radius. It carries a positive rake angle of 10 degrees with a corner-rounded cutting edge style and the PM chip breaker geometry. Four cutting edges per insert maximize tool economy. It is held in the cutter body by a screw-clamp method and is designed for right-hand cutting orientation.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, cast iron, and hard materials in both roughing and finishing operations where CVD-coated carbide grades are indicated. The PM chip breaker geometry supports stable chip control across a range of feed rates and depths of cut up to 9.75 mm. It fits R245 series cutter bodies and is appropriate for machine shops, metalworking facilities, and maintenance operations where consistent insert geometry and ISO- and ANSI-standardized dimensions are required for tooling repeatability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal wear resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 4220 solid carbide substrate rated for material grades P20 and H25\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for extended tool economy\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry for controlled chip evacuation in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (10 degrees) reduces cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003eANSI and ISO standardized: R245-18 T6 M-PM 4220 for direct cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with R245 series milling cutter bodies.

Ensure the milling cutter body is fully secured and the machine spindle is locked or powered down before seating or indexing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer for the screw-clamp holding method. Inspect the insert pocket seating surface for chips or debris before installation to ensure proper insert contact and prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P20, H25\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\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R245\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 18T6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 18.00 mm (0.7087 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 6.10 mm (0.2402 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 13.90 mm (0.7087 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 9.75 mm (0.3839 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.22 mm (0.2244 inches)\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\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\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: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: R245-18 T6 M-PM 4220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R245-18 T6 M-PM 4220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.48 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 5743968\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51736550736178,"sku":"5743968","price":467.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57d44f9d37c7d023a61f03067cec3f35_f04ad798-64a6-4d04-b3f1-8804e45e669a.jpg?v=1788778611","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5743968-milling-insert-4220-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
