Built to the R390 series standard, this parallelogram-shaped insert carries a three-layer CVD coating  -  TiCN, Al2O3, and TiN  -  applied under manufacturer grade 4340. The coating sequence delivers wear resistance and thermal stability across a broad range of cutting conditions. At 0.1875 inches thick with a 0.3780-inch inscribed circle and a 0.2500-inch corner radius, it is dimensioned for precision fitment in R390-compatible toolholders. Installation and operation are handled by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling steel, stainless steel, and cast iron, covering material application codes P, M, and K. The PM chip breaker geometry supports a positive rake angle of 17 degrees, promoting efficient chip evacuation and reduced cutting forces. It is suited for both roughing and semi-finishing passes where a maximum depth of cut reaches 0.5906 inches. The right-hand cutting configuration and screw-holding method make it a standard drop-in for R390 series face mills and shoulder mills used in production machining of ferrous and austenitic workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with three-layer CVD coating: TiCN, Al2O3, and TiN for extended tool life\u003c\/li\u003e\n  \u003cli\u003eParallelogram insert shape with 90-degree included angle and positive 17-degree rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e0.2500-inch corner radius minimizes edge chipping on interrupted cuts and hard materials\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry supports efficient chip control across steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.5906 inches supports both roughing and semi-finishing strategies\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert, single-sided, with screw-lock holding for secure seating at high feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in R390 series indexable milling cutters.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to seat the clamping screw to the toolholder manufacturer's specification  -  do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before placing the new insert to ensure full contact and proper edge height.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: R390\u003c\/li\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\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\u003eChip Breaker\u003c\/strong\u003e: PM\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\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Range\u003c\/strong\u003e: 0.1850 to 0.2000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3780 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Range\u003c\/strong\u003e: 0.3500 to 0.4000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.2500 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3780 inches (9.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6181 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Range\u003c\/strong\u003e: 0.6000 to 0.6500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5906 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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 170464\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R390-17 04 64E-PM 4340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R390-17 04 64E-PM 4340\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.018 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 7564395\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51740026110258,"sku":"7564395","price":70.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38ecf10af004d4d2005ddc0bc549caf7_5aeacdbc-b1eb-4b6c-b690-814e32de83f6.jpg?v=1788821582","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7564395-milling-insert-r390-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
