It features a PVD-applied TiAlN coating optimized for cutting steel, stainless steel, cast iron, and superalloys including titanium. The octagon insert shape delivers 8 usable cutting edges from a single-sided geometry, extending tool life between changeovers. With a positive rake angle of 5 degrees, a honed cutting edge style, and a GB chip breaker, the insert promotes controlled chip formation and reduced cutting forces across a range of milling operations. It is held in the cutter body by a screw-type clamping method and is compatible with the KSOM cutter series.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for face milling and shoulder milling applications in both production and job-shop environments. Primary workpiece materials are steel (P), stainless steel (M), cast iron (K), and superalloys and titanium (S). The maximum depth of cut reaches 0.2360 inches. It fits KENNAMETAL KSOM series cutter bodies. Typical users include CNC machinists and manufacturing facilities running general-purpose milling on ferrous and difficult-to-machine materials. The neutral hand orientation allows use in a range of toolholder configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiAlN coating for heat and wear resistance on steel, stainless, cast iron, and superalloys\u003c\/li\u003e\n  \u003cli\u003eOctagon insert shape with 8 cutting edges per insert, maximizing edge utilization\u003c\/li\u003e\n  \u003cli\u003ePositive 5-degree rake angle with honed edge prep for reduced cutting forces and edge chipping\u003c\/li\u003e\n  \u003cli\u003eGB chip breaker geometry promotes chip control across a range of feed rates and depths\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.2360 inches suitable for moderate material removal passes\u003c\/li\u003e\n  \u003cli\u003eScrew-held, single-sided, neutral-hand insert compatible with KSOM cutter series bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL KSOM series cutter bodies.

Verify cutter pocket geometry and screw torque specifications against the KSOM toolholder documentation before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct Torx or hex key specified by the cutter body documentation to secure the clamping screw — do not overtighten, as carbide inserts are brittle and can crack under excess clamping force. Inspect the insert pocket and screw threads for damage or debris before fitting a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: OFKT06L5AFENGB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: OFKT53AFEN4GB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC522M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Octagon\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\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\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm, 1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5787 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches (0.22 mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 53\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: KSOM\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade Codes\u003c\/strong\u003e: P, M, K, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0154 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2458790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753780150578,"sku":"2458790","price":227.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77c9bb33dd509bb2a5b609853a534d7c.jpg?v=1788940639","url":"https:\/\/voomisupply.com\/products\/kennametal-2458790-milling-insert-kc522m-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
