It carries an octagonal shape with 8 cutting edges per insert, making it a cost-effective choice for production environments. The insert is coated with TiAlN via a PVD process under the IC950 manufacturer grade, which provides heat resistance and wear protection at the cutting edge. At 0.179 inches thick with an inscribed circle of 0.701 inches, this neutral-hand insert fits standard HELIOCTO toolholders and is installed by machinists and tool-and-die professionals in CNC and conventional milling applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for cutting steel and cast iron, corresponding to ISO material groups P and K. It is suited for both roughing and finishing passes where a positive rake geometry and a honed cutting edge style are preferred. The chip breaker designation 76 governs the edge geometry and chip flow characteristics for those material groups. With a maximum depth of cut of 0.209 inches and a cutting edge effective length of 0.209 inches, it fits a range of axial engagement scenarios in production milling. The screw-holding method provides secure clamping in compatible toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOctagonal insert with 8 cutting edges for extended tool life per insert\u003c\/li\u003e\n  \u003cli\u003eIC950 grade with TiAlN PVD coating for wear resistance in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with honed cutting edge for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eChip breaker designation 76 optimized for P and K material groups\u003c\/li\u003e\n  \u003cli\u003eNeutral hand — compatible with both left- and right-hand toolholder configurations\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards for insert identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISCAR HELIOCTO series milling toolholders that accept OFMR 0704 insert seats.

Index or replace the insert only after the spindle is fully stopped and the machine is locked out per shop safety procedures. Inspect the insert pocket and seating surface for chips or debris before installing a fresh edge. Machining professionals should follow applicable shop safety standards and toolholder manufacturer guidelines when setting cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: OFMR\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\u003eManufacturer Grade\u003c\/strong\u003e: IC950\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\u003eSeries\u003c\/strong\u003e: HELIOCTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 0704\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1790 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.7010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.7010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2090 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.2090 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 25 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: 76\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1, C2, C3, C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: OFMR 0704AER-76 IC950\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: OFMR 0704-AER-76\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 5691868\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51735938761010,"sku":"5691868","price":293.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2ca4623ea2a1de8b22a076965a088f7.jpg?v=1788775013","url":"https:\/\/voomisupply.com\/products\/iscar-5691868-milling-insert-octagon-ic950-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
