It carries a parallelogram shape with a 90-degree included angle and a right-hand cutting orientation. The insert is PVD-coated with AlTiCrN for extended tool life across a wide range of workpiece materials. At 3.97 mm thick and 11 mm wide, it delivers a maximum depth of cut of 10 mm. The chip breaker geometry is PH with a positive rake angle of 11 degrees and a corner radius of 1.00 mm, making it well suited for finishing and semi-finishing operations on steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. Licensed machinists and CNC tooling specialists install this insert in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is used in horizontal and vertical milling centers running R390-series toolholders. It is applicable to both roughing and finishing passes on steel and stainless steel components, as well as non-ferrous and titanium workpieces. The PH chip breaker geometry is optimized for light-to-medium chip loads, helping maintain surface finish quality and reducing vibration during interrupted cuts. The two available cutting edges allow the insert to be indexed once before replacement, providing cost-per-edge efficiency in high-volume machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiCrN PVD coating for thermal resistance and wear performance on steel, stainless steel, titanium, and hard materials\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 11 degrees reduces cutting forces and heat generation\u003c\/li\u003e\n\u003cli\u003e1.00 mm corner radius with rounded cutting edge style for smooth surface finish\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 10 mm supports productive shoulder milling operations\u003c\/li\u003e\n\u003cli\u003eSingle-sided insert with 2 cutting edges for indexable cost efficiency\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting for secure clamping and repeatable insert positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with R390 and M-32 cutter series toolholders per ANSI and ISO designations.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key torque driver for the clamping screw to avoid stripping the screw seat or cracking the insert. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1130\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P30, M15, N15\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\u003eChip Breaker\u003c\/strong\u003e: PH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 11T310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 11.00 mm (0.2677 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.97 mm (0.1413 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2677 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.11 mm (0.1102 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\u003eRelief Angle\u003c\/strong\u003e: 21 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 11 degrees positive\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Non-Ferrous Metal, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: M-32, R390\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R390-11 T3 10M-PH 1130\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R390-11 T3 10M-PH 1130\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: 0.08 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: 6906944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51752432304434,"sku":"6906944","price":414.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/834aa23dc56a54fde8a41e73c1e59e1e_f1ef50c4-c5b9-4ef7-bd76-c5db2927eb82.jpg?v=1788928093","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6906944-milling-insert-r390-grade-1130","provider":"Voomi Supply","version":"1.0","type":"link"}
