It features a PVD-applied multilayer coating of TiN, TiCN, and TiN, which delivers elevated wear resistance and thermal stability at the cutting edge. The square insert geometry with a 90-degree included angle and LD2 chip breaker is designed for positive cutting action in milling applications. At 0.188 inches thick with a 0.5-inch inscribed circle and a 0.0315-inch corner radius, this insert is screw-held and right-hand oriented, suitable for use in compatible SDCT-series milling toolholders and cutters.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling steel, stainless steel, superalloys, and titanium workpiece materials, covering ISO material groups P, M, and S. It is well-suited for face milling, shoulder milling, and general-purpose milling operations where consistent edge life and chip control across difficult-to-machine alloys are required. Licensed machinists, tooling technicians, and CNC operators working in production or job-shop environments are the typical end users. The LD2 chip breaker geometry supports controlled chip formation across a range of feeds and depths of cut appropriate to the material grades C5, C6, and C7.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePVD multilayer coating: TiN, TiCN, TiN for extended wear resistance in steel and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003eLD2 chip breaker for controlled chip formation across varied feed rates\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle for shoulder and face milling\u003c\/li\u003e\n  \u003cli\u003e0.0315-inch corner radius reduces cutting forces and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting method for secure, repeatable seating in SDCT toolholders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation; inscribed circle of 0.394 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SDCT-series milling toolholders and cutters accepting size 43 square inserts with a 0.1732-inch hole diameter.

Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert. Do not force the insert into the pocket; improper seating can cause premature edge failure or toolholder damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Designation\u003c\/strong\u003e: SDCT1204PDERLD2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SDCT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\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, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LD2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.394 inches (range 0.5000 to 0.5100 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.188 inches (range 0.1850 to 0.2000 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\u003eInsert Size Code\u003c\/strong\u003e: 43\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: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0152 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: 2390253\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748731781426,"sku":"2390253","price":200.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e8a9fd660491f64f9e0044311de98d3.jpg?v=1788897442","url":"https:\/\/voomisupply.com\/products\/kennametal-2390253-milling-insert-sdct1204pderld2-kc725m","provider":"Voomi Supply","version":"1.0","type":"link"}
