The insert follows an SDET series square geometry with a 90-degree included angle and a right-hand cutting orientation. It measures 0.1875 inches thick with a 0.5000-inch inscribed circle and a corner radius of 0.0315 inches (approximately 0.80 mm). The GB2 chip breaker geometry is designed to control chip formation during milling operations in cast iron. Screw-style insert holding secures the insert in compatible toolholders. This insert is intended for installation by machinists and tooling technicians on CNC or manual milling equipment.\u003c\/p\u003e\n\u003cp\u003eThe SDET1204PDSRGB2 insert in KC520M grade is engineered primarily for milling cast iron workpieces, classified under primary workpiece material code K. It is suited for face milling, shoulder milling, and similar interrupted-cut applications where controlled chip flow and edge integrity in ferrous materials are required. The PVD TiAlN coating provides thermal and oxidation resistance appropriate for dry or semi-dry cast iron milling conditions. This insert is sold individually with a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC520M solid carbide grade with PVD TiAlN coating for cast iron milling\u003c\/li\u003e\n  \u003cli\u003eSquare SDET insert geometry with 90-degree included angle and right-hand orientation\u003c\/li\u003e\n  \u003cli\u003eGB2 chip breaker for controlled chip evacuation in cast iron applications\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0315 inches (0.80 mm) for edge strength and surface finish\u003c\/li\u003e\n  \u003cli\u003eScrew-style clamping method for positive insert retention in the toolholder\u003c\/li\u003e\n  \u003cli\u003eISO designation SDET1204PDSRGB2 for direct cross-reference and replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SDET-series compatible milling toolholders that accept a square insert with a 0.5000-inch inscribed circle, 0.1875-inch thickness, and screw-type clamping.

Power down and lock out the machine spindle before changing inserts. Use the correct torque screwdriver or Torx key specified by the toolholder manufacturer to seat the clamping screw — do not over-tighten or substitute fasteners. Inspect the insert pocket seat for chips or debris before seating the new insert, as contamination in the pocket will affect insert stability and edge life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SDET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SDET1204PDSRGB2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC520M\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: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GB2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\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\u003eMaterial Grade\u003c\/strong\u003e: C1, C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0168 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: 5\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: 2390289\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755423433010,"sku":"2390289","price":202.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d181dbdfbec21e664362471d7100856e.jpg?v=1788954891","url":"https:\/\/voomisupply.com\/products\/kennametal-2390289-milling-insert-kc520m-tialn-square","provider":"Voomi Supply","version":"1.0","type":"link"}
