It features a fine-grain carbide substrate coated via CVD with a TiCN and Al2O3 Duratomic multilayer coating for extended wear resistance and thermal stability. The octagon insert shape delivers 16 usable cutting edges per insert, reducing tooling cost per edge. With a negative rake angle of 15 degrees and a T-Land cutting edge style, this insert is built for aggressive material removal on steel and related workpiece materials. Installation and use require a compatible milling cutter body.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling applications in steel as its primary workpiece material, with rated capability in stainless steel, cast iron, superalloys, and titanium. The neutral hand orientation makes it adaptable across a range of face milling setups. It carries ISO material grade codes P, M, K, and S, covering a broad spectrum of CNC machining environments in both production and job-shop settings. Machining technicians and CNC programmers working with demanding alloy families will find this insert appropriate for moderate to heavy depth-of-cut passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16 cutting edges per insert from double-sided octagon geometry, maximizing value per insert\u003c\/li\u003e\n  \u003cli\u003eCVD-applied TiCN and Al2O3 Duratomic coating for heat and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eFine-grain solid carbide substrate for edge integrity under high cutting forces\u003c\/li\u003e\n  \u003cli\u003eNegative rake at 15 degrees with T-Land edge prep for strength on interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3031 inches with a cutting edge effective length of 0.3031 inches\u003c\/li\u003e\n  \u003cli\u003eCompatible with R220.48-09 and L220.48-09 cutter series bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with R220.48-09 and L220.48-09 cutter series bodies.

Ensure the milling cutter body is fully powered down and spindle is locked before seating or replacing inserts. Use the correct torx or hex key to the cutter manufacturer torque specification shown in the cutter body documentation. Inspect the insert pocket seating surface for chips or debris before installation to prevent insert rocking and premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ONMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Octagon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: MP2501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3 (Duratomic, CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 090520\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ONMU-09\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative, 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.8661 inches (22.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2189 inches (5.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2205 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.3031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0787 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Cast Iron, Superalloys and Titanium (ISO Codes M, K, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: ONMU090520ANTN-M15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R220.48-09, L220.48-09\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble Sided\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03273007\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560205156658,"sku":"03273007","price":71.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/020ce9337a757f02e632aad44e518b28.jpg?v=1786449236","url":"https:\/\/voomisupply.com\/products\/seco-03273007-milling-insert-mp2501-solid-carbide-octagon","provider":"Voomi Supply","version":"1.0","type":"link"}
