It carries the 4220 manufacturer grade with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, providing wear resistance and thermal protection during demanding cutting operations. The insert features a square shape with a 90-degree included angle, a positive 10-degree rake angle, and a corner radius of 1.40 mm (0.0551 inches). It holds to ISO and ANSI code R210-09 04 14E-PM 4220 and is intended for professional machining applications requiring consistent edge geometry and reliable chip control. Machinists and tooling specialists are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel and cast iron workpieces in both roughing and finishing passes where controlled depth of cut is needed. The PM chip breaker geometry supports stable chip evacuation across these material groups. With a maximum depth of cut of 1.00 mm (0.0472 inches), this insert is best applied in light-to-moderate passes where edge integrity and surface finish consistency are priorities. It fits standard R210 series toolholders and is a direct replacement insert for worn or depleted positions in those cutter bodies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended wear life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and positive 10-degree rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 1.40 mm (0.0551 inches) for corner-rounded cutting edge style\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry promotes stable chip formation and evacuation\u003c\/li\u003e\n  \u003cli\u003eSingle-sided insert with 4 cutting edges, screw-mounted retention\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; catalog code R210-09 04 14E-PM 4220\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SANDVIK COROMANT R210 series milling cutter bodies.

Always power down and lock out the spindle before handling inserts or toolholders. Use a torx or hex key appropriate for the insert clamping screw per the cutter body manufacturer specification. Inspect the cutter body pocket and seating surfaces for wear or debris before seating a new insert to ensure proper edge geometry and runout.\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\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: R210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.50 mm (0.3740 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.50 mm (0.1772 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.40 mm (0.0551 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.77 mm (0.3740 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.17 mm (0.1654 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.00 mm (0.0472 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\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\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\u003eMaterial Grade\u003c\/strong\u003e: P20, H25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R210-09 04 14E-PM 4220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R210-09 04 14E-PM 4220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 090414\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: 0.1 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: 5742742\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731610829106,"sku":"5742742","price":416.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4497b05794e30407871f52ee4d377bf0_bd59dc29-035e-4287-9da9-0b8966512920.jpg?v=1788733137","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5742742-milling-insert-4220-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
