Carrying the ANSI and ISO designation R390-11 T3 16M-PM 1130, this insert features a parallelogram shape with a 90-degree included angle, a positive rake geometry at 25 degrees, and a 21-degree relief angle. The AlTiCrN coating is applied via PVD process under the manufacturer grade 1130, delivering thermal resistance and edge durability across demanding cutting conditions. It measures 11.00 mm wide and 3.97 mm thick, with a 1.60 mm corner radius. Holding method is screw-on, and the insert is single-sided with two cutting edges per insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use in R390 and M-32 series cutter bodies in both roughing and semi-finishing operations. Primary workpiece materials include steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials, covering material grades P30, M15, and N15. It is a right-hand insert with a PM chip breaker geometry, making it appropriate for general-purpose milling where chip control and insert life are priorities. Licensed machinists and CNC operators in production shops, job shops, and maintenance environments are the typical end users. Maximum depth of cut is 10.00 mm.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with AlTiCrN PVD coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry for effective chip control across multiple material types\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 25 degrees reduces cutting forces on workpiece and spindle\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert for extended tool life per insert consumed\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation with screw-on mounting for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with R390 and M-32 series cutter bodies. ANSI code R390-11 T3 16M-PM 1130 and ISO code R390-11 T3 16M-PM 1130 are both applicable. Insert size code is 11T316.

Always power down and lock out the machine spindle before seating or removing inserts. Use the correct torque driver for the cutter body screw to avoid damaging the insert pocket or seating surface. Inspect the insert pocket and shim seat for debris or wear before installing a new insert, and confirm correct insert orientation for right-hand cut direction.\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\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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: 1.60 mm (0.0630 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\u003eHole Diameter\u003c\/strong\u003e: 0.11 mm (0.1102 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 25 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 21 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 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\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\u003eInsert Size Code\u003c\/strong\u003e: 11T316\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Non-Ferrous Metal, Superalloys, 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: R390-11 T3 16M-PM 1130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R390-11 T3 16M-PM 1130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.051 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 6906947\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51735268786482,"sku":"6906947","price":394.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/834aa23dc56a54fde8a41e73c1e59e1e_4b9c7f70-d9b7-40eb-8b70-e569589e37c7.jpg?v=1788771266","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6906947-milling-insert-r390-11mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
