It carries a CVD-applied multilayer coating of TiN, TiCN, and Al2O3 under manufacturer grade KCK15, which targets ferrous and cast iron material groups. The insert measures 0.1875 inches thick with an inscribed circle of 0.5000 inches and a corner radius of 0.0630 inches (1.60 mm). Holding is via screw clamp. This insert is a neutral-hand, square-profile style intended for use by machinists and CNC tooling specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe SDET120416SNGB2 insert is suited for milling cast iron components in both roughing and semi-finishing applications. The GB2 chip breaker geometry supports controlled chip evacuation in cast iron cuts where abrasive wear resistance is a primary concern. The 90-degree included angle and 15-degree relief angle provide clearance geometry appropriate for shoulder and face milling tool bodies that accept SDET-style inserts. This insert is appropriate for production machining on CNC machining centers as well as manual milling machines where cast iron is the primary workpiece material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCK15 solid carbide grade with CVD-deposited TiN, TiCN, and Al2O3 multilayer coating for cast iron cutting\u003c\/li\u003e\n\u003cli\u003eSquare SDET insert style with neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eGB2 chip breaker geometry for controlled chip flow in cast iron\u003c\/li\u003e\n\u003cli\u003e0.0630 inch (1.60 mm) corner radius for edge strength and surface finish balance\u003c\/li\u003e\n\u003cli\u003e15-degree relief angle reduces cutting forces and tool body clearance conflicts\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method for positive, repeatable insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for milling tool bodies that accept SDET-series square inserts with a 0.1732 inch hole diameter and 0.5000 inch inscribed circle, intended for cast iron milling applications (Material Application Code K).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct torque screwdriver or Torx key specified by the tool body manufacturer for the clamping screw — do not overtighten. Inspect the insert pocket seat and clamping screw threads for wear or debris before seating the new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SDET\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: KCK15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, TiCN, Al2O3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GB2\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: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0630 inches (1.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\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: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SDET120416SNGB2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.019 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 2458916\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729654776114,"sku":"2458916","price":54.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f14fd254a6211e7ab5bad9beac30812a.jpg?v=1788707274","url":"https:\/\/voomisupply.com\/products\/kennametal-2458916-milling-insert-kck15-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
