Carrying the ANSI and ISO designation R390-11 T3 24E-PM 1130, this parallelogram-shaped, right-hand insert measures 11 millimeters wide and 3.97 millimeters thick. It features an AlTiCrN coating applied via PVD process, grade 1130, with a positive rake angle of 25 degrees and a 21-degree relief angle. The PM chip breaker geometry supports stable cutting and effective chip control. Machinists and tooling technicians working in high-mix production environments install these inserts in compatible R390-series cutter bodies.\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 P, M, N, S, and H. It is a single-sided insert with two cutting edges, a 90-degree included angle, and a corner radius of 2.40 millimeters. The maximum depth of cut reaches 10 millimeters. Typical applications include shoulder milling, pocket milling, and ramping in both roughing and semi-finishing passes on CNC machining centers in job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrN coating via PVD process for wear resistance across steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 25 degrees reduces cutting forces and supports lighter machine spindles\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry promotes effective chip evacuation in wet and dry cutting\u003c\/li\u003e\n  \u003cli\u003e2.40 mm corner radius balances surface finish quality with edge strength\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with screw-locking insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eCompatible with material grades P, M, N, S, and H — broad workpiece material range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M-32 and R390 cutter series bodies per manufacturer specifications.

Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key to tighten the clamping screw to the cutter body manufacturer's specification — do not overtighten, as this can crack the carbide. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper insert orientation and secure seating.\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: 1130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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: PM\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: 2.40 mm (0.0945 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\u003eInscribed Circle\u003c\/strong\u003e: 0.2677 inches\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: 25 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\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\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 Codes\u003c\/strong\u003e: P, M, N, S, H\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 24E-PM 1130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R390-11 T3 24E-PM 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: 0.07 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: 6906949\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731110822194,"sku":"6906949","price":539.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8e9b220c0cd9f2ef7f36fc5081387b0.jpg?v=1788727083","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6906949-milling-insert-r390-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
