Manufactured to ANSI and ISO standards under the OFEN-07 series, this single-sided insert carries a CVD-applied Duratomic TiCN plus Al2O3 coating for wear resistance and thermal stability at the cutting edge. It features a neutral rake angle, T-Land cutting edge style, and a D18 chip breaker geometry. The insert measures 0.7071 inches in inscribed circle diameter and 0.1874 inches thick, weighing 0.03 pounds. Installation requires a wedge clamp holding method in a compatible cutter body.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for machining cast iron workpieces in production milling environments. The octagon shape delivers 8 cutting edges per insert, maximizing tool life and cost-per-edge efficiency. With a maximum depth of cut of 0.2756 inches and a cutting edge effective length of 0.2917 inches, it fits mid-range material removal passes on both horizontal and vertical milling setups. It is sold individually but must be ordered in multiples of 10. Machinists and tooling specialists working with cast iron components will find the D18 chip breaker geometry effective for chip control in these materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate with CVD Duratomic TiCN plus Al2O3 coating for extended wear life in cast iron\u003c\/li\u003e\n  \u003cli\u003eOctagon insert shape provides 8 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eNeutral rake and T-Land cutting edge style for stable entry and reduced chipping\u003c\/li\u003e\n  \u003cli\u003eD18 chip breaker geometry optimized for cast iron chip control\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 0.2756 inches with cutting edge effective length of 0.2917 inches\u003c\/li\u003e\n  \u003cli\u003eWedge clamp holding method; compatible with SECO R220.43-07 cutter series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the SECO R220.43-07 cutter series.

Always power down and lock out the spindle before changing inserts. Use a torx or hex key appropriate to the wedge clamp fastener in the cutter body; do not overtighten the clamp screw beyond the cutter manufacturer specification. Inspect the pocket seating surface for chips or debris before seating the insert to ensure proper contact and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: OFEN\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: MK1500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN plus Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: Duratomic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.7071 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.2917 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2756 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 Angle\u003c\/strong\u003e: 0 degrees (Neutral)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 26 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: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: D18\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: Wedge Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Material Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R220.43-07\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: OFEN070405TN-D18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\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: 0.03 pounds\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\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: 02566028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558205325618,"sku":"02566028","price":465.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f5eb9ca27af0aa54b948313776a895d.jpg?v=1786406149","url":"https:\/\/voomisupply.com\/products\/seco-02566028-octagon-milling-insert-solid-carbide-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
