It is an octagonal, double-sided insert with 16 usable cutting edges, a TiAlN coating applied by PVD, and a negative rake geometry with a T-Land cutting edge style. The inscribed circle measures 0.7953 inches, thickness is 0.2360 inches, and the corner radius is 0.0315 inches (1\/32 inch). The MM chip breaker geometry is optimized for controlled chip evacuation across a wide range of workpiece materials. This insert is used by machinists and tool-and-die professionals in production milling operations.\u003c\/p\u003e\n\u003cp\u003eThe ONMU 080608-TN-MM IC908 is designed for face milling and shoulder milling applications on steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, and H). Its IC908 submicron carbide substrate combined with PVD TiAlN coating makes it well suited for demanding cuts where heat resistance and edge toughness are priorities. The insert belongs to the ISCAR 16MILL series and is confirmed compatible with ISCAR cutter bodies in the F45NM and F45WG series. Maximum depth of cut is 0.2170 inches (5.50 mm). Typical applications include production environments with CNC vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16 cutting edges per insert — double-sided octagonal geometry maximizes cost-per-edge value\u003c\/li\u003e\n  \u003cli\u003eIC908 submicron solid carbide grade with PVD TiAlN coating for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMM chip breaker promotes reliable chip control across steel, stainless, and hard material applications\u003c\/li\u003e\n  \u003cli\u003eNegative rake with T-Land edge prep provides edge strength during interrupted and heavy cuts\u003c\/li\u003e\n  \u003cli\u003eNeutral hand designation allows use in both climb and conventional milling orientations\u003c\/li\u003e\n  \u003cli\u003eScrew-holding method ensures positive insert location and repeatable seating in the cutter pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConfirmed compatible with ISCAR F45NM and F45WG series cutter bodies.

Use the appropriate Torx or hex key for the clamping screw as specified by the cutter body manufacturer — do not overtighten, as this can fracture the insert or damage the pocket seat. Inspect the pocket seat and screw threads for debris or wear before seating a new insert. Handle solid carbide inserts carefully to avoid chipping edges prior to use.\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: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 080608\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\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\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.7953 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2170 inches (5.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.2170 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: F45NM, F45WG\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16MILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0125 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5605189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51754918117682,"sku":"5605189","price":47.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f2d46ecf686d5c3966c5bdd8f678176.jpg?v=1788949762","url":"https:\/\/voomisupply.com\/products\/iscar-5605189-milling-insert-onmu-080608-tn-mm-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
