It carries manufacturer grade 4220 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for extended tool life in demanding cuts. The insert has a square shape with a positive rake geometry, a corner radius of 0.0394 inches (1.00 mm), and delivers four usable cutting edges per insert. Thickness measures 0.1875 inches (4.76 mm) and the inscribed circle diameter is 0.5709 inches (14.50 mm). It is held in the cutter body by a screw and is right-hand oriented with a PM chip breaker configuration.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling operations on steel, cast iron, and hard materials, corresponding to ISO material groups P, K, and H. Material grades P20 and H25 apply. It is used in production and job-shop environments where consistent chip control and wear resistance are required across a range of depths of cut up to 0.0787 inches (2.00 mm). The ANSI and ISO designation for this insert is R210-14 05 12M-PM 4220. Installation is performed by CNC machinists and toolroom technicians setting up R210-compatible milling cutter bodies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with CVD multilayer TiCN, Al2O3, and TiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert with positive rake angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0394 inches (1.00 mm) for controlled corner engagement\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry suited for steel and cast iron applications\u003c\/li\u003e\n\u003cli\u003eScrew-lock insert holding method for secure seating in the cutter body\u003c\/li\u003e\n\u003cli\u003eCompliant with both ANSI and ISO standards; catalog designation R210-14 05 12M-PM 4220\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with R210 series milling cutter bodies.

Use the correct Torx or hex key as specified by the cutter body manufacturer to seat and secure the screw-lock fastener. Inspect the cutter pocket and seating surface for chips or debris before installing a new insert. Index or replace all inserts in a cutter body at the same time to maintain balanced cutting forces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R210\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: 4220\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P20; H25\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\u003eCorner Radius\u003c\/strong\u003e: 0.0394 inches (1.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.5709 inches (14.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5709 inches (11.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2244 inches (0.22 mm nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0787 inches (2.00 mm)\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: 0 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\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, Cast Iron, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R210-14 05 12M-PM 4220\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R210-14 05 12M-PM 4220\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: 0.26 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: 5742556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737345327410,"sku":"5742556","price":394.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd3ce8108b7b8baa0cf7aa3507009448_0b2be054-61c8-4f3c-bb1c-2592e2e7c140.jpg?v=1788787388","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5742556-r210-square-milling-insert-4220","provider":"Voomi Supply","version":"1.0","type":"link"}
