Manufactured to ANSI and ISO standards under the designation R390-11 T3 04M-PM 1130, this insert features a parallelogram shape with a positive rake angle of 25 degrees and a 21-degree relief angle. The PVD-applied AlTiCrN coating delivers heat and wear resistance across demanding cutting conditions. With two cutting edges and a corner radius of 0.40 mm, it provides controlled chip formation through the PM chip breaker geometry. Licensed machinists and CNC tooling technicians working in production environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials, covering material grades P30, M15, and N15. It fits right-hand toolholders in the R390 and M-32 cutter series. Typical applications include shoulder milling, face milling, and ramping operations where precise depth of cut control is required. The insert size code 11T304 and screw-clamping retention method make it compatible with standard R390-series pockets. Production shops running multi-material schedules benefit from the broad material application range this grade supports.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrN PVD coating for elevated wear resistance in steel and stainless steel cutting\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry optimized for positive-rake milling with controlled chip flow\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert for extended tool economy\u003c\/li\u003e\n  \u003cli\u003e0.40 mm corner radius with corner-rounded cutting edge style reduces insert chipping at entry\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 10.00 mm suits both roughing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eScrew-clamping retention method ensures rigid seating under high feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in R390 and M-32 series milling cutter bodies accepting 11T304 insert pockets with screw-clamp retention.

Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key to the cutter manufacturer's specified clamp-screw procedure — do not overtighten, as this can fracture the carbide body. Inspect the insert pocket seating surface for debris or wear before installing a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI \/ ISO Code\u003c\/strong\u003e: R390-11 T3 04M-PM 1130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: R390\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\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 11T304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\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\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\u003eRake\u003c\/strong\u003e: Positive\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\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\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\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 and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P30, M15, N15\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.073 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: 6906909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51754496852274,"sku":"6906909","price":396.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/834aa23dc56a54fde8a41e73c1e59e1e_85ae6c1b-4344-4ae5-a0cf-a5d66f6432ed.jpg?v=1788946027","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6906909-milling-insert-r390-1130","provider":"Voomi Supply","version":"1.0","type":"link"}
