This octagon-shaped, single-sided insert features 8 cutting edges, a positive rake geometry, and a sharp cutting edge style suited for high-productivity milling applications. The multilayer Sumotec PVD coating — TiAlN, AlTiN, and TiN — applied via physical vapor deposition, delivers thermal resistance and edge wear protection across a broad range of workpiece materials. The insert measures 0.5689 inches in inscribed circle diameter and 0.1930 inches thick, with a corner radius of 0.0197 inches (0.50 mm). It is held in the cutter body by screw clamping and is compatible with neutral-hand toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, making it suitable for general-purpose and demanding production environments in aerospace, automotive, die-mold, and heavy equipment machining. The AER chip breaker geometry supports effective chip control at moderate to aggressive depths of cut up to 0.1460 inches (3.70 mm). The submicron carbide substrate contributes to toughness and edge integrity when machining difficult ISO P, M, K, S, and H material groups. Licensed machinists and CNC tooling technicians typically specify and install this insert in horizontal and vertical milling centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOctagon insert shape with 8 cutting edges per insert for extended tool life per unit cost\u003c\/li\u003e\n  \u003cli\u003eIC808 grade with Sumotec PVD multilayer coating (TiAlN, AlTiN, TiN) for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003ePositive rake and sharp cutting edge style reduce cutting forces on difficult materials\u003c\/li\u003e\n  \u003cli\u003eAER chip breaker for reliable chip control in steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.1460 inches (3.70 mm) with effective cutting edge length of 0.1460 inches\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide substrate for added toughness in superalloy and hard material milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with HELIOCTO series cutter bodies HOF-R06 and HOE-R06 as specified by the manufacturer.

Power down and lock out the machine spindle before replacing inserts. Seat the insert fully in the pocket and secure with the clamping screw to the toolholder manufacturer's specified procedure using a calibrated torque driver. Inspect the insert pocket and seating surface for chips or debris before installation to prevent improper seating 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: OECR\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: IC808\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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN, AlTiN, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: Sumotec PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5689 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1930 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5689 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5689 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0197 inches (0.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1460 inches (3.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.1460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: AER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HELIOCTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: HOF-R06, HOE-R06\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: OECR 060405AER IC808\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: OECR 060405AER\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: 0.5 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: 5668057\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748352524594,"sku":"5668057","price":368.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8df72fb7151357a805be83a4c132f488.jpg?v=1788892827","url":"https:\/\/voomisupply.com\/products\/iscar-5668057-milling-insert-oecr-060405aer-ic808-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
