The insert features an octagon shape with a neutral hand orientation, a negative rake angle of 20 degrees, and a T-Land cutting edge style. Sixteen usable cutting edges are available across a double-sided configuration, making it a high-value option for production milling environments. The inscribed circle measures 0.8661 inches, thickness is 0.2677 inches, and the corner radius is 0.0787 inches. Licensed machinists and CNC mill operators working in aerospace, energy, and precision manufacturing are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for milling superalloys and titanium, with secondary suitability for steel and stainless steel. The ME13 chip breaker geometry is optimized for the interrupted and continuous cuts common in those difficult-to-machine materials. Maximum depth of cut reaches 0.3031 inches with an effective cutting edge length of 0.3031 inches. The insert seats and locks via screw-holding method, compatible with SECO cutter series R220.48-09 and L220.48-09. It is appropriate for both roughing and semi-finishing passes in high-temperature alloy and titanium machining applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMS2050 micrograin carbide grade with PVD TiAlN and NbN coating for heat and wear resistance in superalloy and titanium cuts\u003c\/li\u003e\n\u003cli\u003e16 cutting edges on a double-sided octagon insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eME13 chip breaker geometry tuned for superalloys, titanium, steel, and stainless steel\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of 20 degrees with T-Land edge prep for edge strength and stability\u003c\/li\u003e\n\u003cli\u003eScrew-clamped seating for repeatable positioning and secure insert retention\u003c\/li\u003e\n\u003cli\u003ePVD coating process preserves sharp edge geometry at the substrate level\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SECO cutter series R220.48-09 and L220.48-09.

Use the correct Torx or hex key as specified by the cutter body manufacturer when seating the clamping screw — do not over-torque or substitute fasteners. Inspect the insert pocket for chips, debris, or wear before seating a new insert. Verify insert orientation and cutting edge engagement against the cutter body documentation before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: ONMU090520ANTN-ME13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: ONMU090520ANTN-ME13\u003c\/li\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: MS2050\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiAlN and NbN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 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: ME13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.8661 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2677 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.8661 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\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\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\u003eCutter Series Compatibility\u003c\/strong\u003e: R220.48-09 and L220.48-09\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: Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel and Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1 pound\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 02899500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563840110898,"sku":"02899500","price":703.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d76f0bbfb622935f75421c9a3852e04.jpg?v=1786504637","url":"https:\/\/voomisupply.com\/products\/seco-02899500-milling-insert-onmu090520antn-me13-ms2050","provider":"Voomi Supply","version":"1.0","type":"link"}
