It is a single-sided, right-hand, parallelogram-shaped insert with a 90-degree included angle and a positive rake geometry. The insert measures 9.6 mm wide and 4.76 mm thick, with a 0.25 inch corner radius and two cutting edges. An AlTiCrN coating applied via PVD process enhances wear resistance and heat tolerance, extending tool life in demanding cuts. Licensed machinists and CNC tooling technicians install this insert into compatible R390-series face and shoulder milling cutter bodies.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for face milling, shoulder milling, and pocket milling applications where positive rake geometry and a robust corner radius are required. The PM chip breaker geometry suits a broad range of workpiece materials including steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. It supports a maximum depth of cut of 15.00 mm (0.5906 inches), making it suitable for both roughing and semi-finishing passes in production machining environments. It is typically used on CNC machining centers in job shop, aerospace, and general manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrN PVD coating rated for steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 17 degrees with corner-rounded cutting edge style for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry provides reliable chip control across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 15.00 mm supports both roughing and semi-finishing operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand, single-sided insert with screw-holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ANSI and ISO code R390-17 04 64E-PM 1130\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with R390-series cutter bodies.

Use the appropriate Torx or hex key driver specified by the cutter body manufacturer to seat the clamping screw — do not overtighten or use impact tools on insert screws. Inspect the cutter body pocket and seating surfaces for wear or debris before installing a fresh insert. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R390\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1130\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: AlTiCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9.60 mm (0.3780 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.76 mm (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3780 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6181 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: 15.00 mm (0.5906 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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: 17 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 19.00 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: 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 Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P30, M15, N15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R390-17 04 64E-PM 1130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R390-17 04 64E-PM 1130\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: 6971862\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732880589106,"sku":"6971862","price":467.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/834aa23dc56a54fde8a41e73c1e59e1e_287b799a-dc65-445e-9e34-a8663ab44535.jpg?v=1788747906","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6971862-r390-milling-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
