It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN under manufacturer grade 4340, delivering hardness and thermal resistance across a range of workpiece materials. The insert is parallelogram-shaped with a 90-degree included angle, a positive 22-degree rake angle, and a corner-rounded cutting edge style. Two cutting edges are available per insert. It measures 0.1875 inches thick with an inscribed circle of 0.3780 inches. Screw-down holding secures it in compatible R390 toolholders. CNC machinists and toolroom technicians working in production or job-shop environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary workpiece materials of steel (P), stainless steel (M), and cast iron (K), aligning with ISO material grades P40, M40, and K40. The PM chip breaker geometry supports interrupted and continuous cuts at moderate-to-heavy depths. The right-hand insert orientation suits standard R390 face mill and shoulder mill bodies. Maximum depth of cut reaches 0.6181 inches, making it suitable for roughing and semi-finishing passes in ferrous materials. It is sold individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD multilayer coating: TiCN, Al2O3, TiN for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 4340 rated for P40, M40, and K40 material classifications\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 22 degrees reduces cutting forces on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry supports both roughing and semi-finishing operations\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0945 inches (2.40 mm) for controlled edge strength\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per single-sided insert maximize usable tool life per insert\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting for secure, repeatable seating in R390 toolholders\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 correct Torx or hex key driver specified by the toolholder manufacturer to seat the clamping screw  -  do not overtighten, as this can fracture the insert body. Inspect the insert pocket seat for chips or debris before seating a new insert to ensure full, flat contact. Verify insert orientation matches the right-hand designation of the cutter body before powering the spindle.\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\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\u003eMaterial Grade\u003c\/strong\u003e: P40, M40, K40\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 Size Code\u003c\/strong\u003e: 170424\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\u003eWidth\u003c\/strong\u003e: 0.3780 inches (9.60 mm)\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\u003eLength Range\u003c\/strong\u003e: 0.6000 to 0.6500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0945 inches (2.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\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\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: 22 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 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 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R390-17 04 24E-PM 4340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R390-17 04 24E-PM 4340\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\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: 7564389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51740185067826,"sku":"7564389","price":594.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38ecf10af004d4d2005ddc0bc549caf7_05cce5e0-5fb9-474f-bd46-506bcaa5f756.jpg?v=1788823284","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7564389-r390-milling-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
