Manufactured to insert style SFKN with a square shape and a 90-degree included angle, this insert carries the ACP300 manufacturer grade and features a PVD-applied coating for extended wear resistance and edge integrity. The inscribed circle measures 0.5000 inches and thickness is 0.1563 inches (5\/32 inches nominal). With a relief angle of 25 degrees, the geometry is well-suited for finishing and semi-finishing passes where edge sharpness and surface finish quality are critical. Machinists and CNC operators working in job shops, aerospace, or general manufacturing facilities will find this insert ready for production use.\u003c\/p\u003e\n\u003cp\u003eThe 14HB660 is engineered primarily for cutting stainless steel and carbon steel workpiece materials, covering ISO application codes M and P. These are among the most common material groups encountered in precision machining environments, making this insert a practical choice for shops running mixed-material production schedules. Its square insert shape provides multiple cutting edges, maximizing the number of usable edges per insert and reducing tooling cost per part. The compact form factor with a 0.0880-inch width suits milling cutter bodies designed for SFKN-style inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eACP300 grade solid carbide construction with PVD coating for wear resistance on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle delivers multiple cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eSFKN insert style, size code 12, inscribed circle 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e25-degree relief angle supports clean cutting action on stainless steel and steel\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.1563 inches (5\/32 inches nominal) fits standard SFKN toolholders\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.04 pounds, minimizing dynamic load contribution at high spindle speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style milling insert for SFKN insert size 12 toolholders and milling cutter bodies that accept a 0.5000-inch inscribed circle, 0.1563-inch thick square carbide insert.

Ensure the cutter body is fully de-energized and the spindle is locked out before removing or indexing inserts. Use the correct torx or hex key as specified by the toolholder OEM to avoid stripping the clamp screw. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and prevent 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: SFKN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACP300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches (5\/32 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.0880 inches\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: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 12T3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel (ISO M, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14HB660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51739553562930,"sku":"14HB660","price":167.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70ce2dfa492e6e05daeebbed89140b9f.jpg?v=1788816156","url":"https:\/\/voomisupply.com\/products\/sumitomo-14hb660-acp300-solid-carbide-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
