This square insert carries the KCPM20 manufacturer grade and features a multilayer CVD coating stack of TiN, MT-TiCN, and Al2O3, providing wear resistance and thermal stability across a range of workpiece materials. The insert measures 0.1875 inches thick with a 0.5 inch inscribed circle and a 1\/32 inch corner radius. The right-hand cutting configuration and honed T-Land cutting edge geometry suit high-feed and moderate-depth milling passes. Installation is by screw-holding method.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling steel, stainless steel, cast iron, and hard materials, corresponding to ISO material groups P, M, K, and H. It is a practical choice for shop environments where wear-resistant tooling is needed on difficult-to-machine alloys or hardened workpieces. The 15-degree relief angle supports clean chip evacuation and reduced cutting forces. It is sold individually and is appropriate for professional machinists and tooling technicians running indexable milling cutters that accept the SDPT1204 insert footprint.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCPM20 carbide grade with CVD multilayer coating: TiN, MT-TiCN, and Al2O3 for extended tool life\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle and honed T-Land cutting edge\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation with screw-clamp holding method\u003c\/li\u003e\n\u003cli\u003e0.5 inch inscribed circle and 0.1875 inch thickness for dimensional consistency in the SDPT series\u003c\/li\u003e\n\u003cli\u003e1\/32 inch corner radius (0.0313 decimal inch) for general-purpose milling profiles\u003c\/li\u003e\n\u003cli\u003eRated for steel, stainless steel, cast iron, and hard materials (ISO P, M, K, H)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style milling insert for indexable milling cutter bodies that accept SDPT1204 series inserts.

Before changing inserts, power down the spindle completely and follow lockout\/tagout procedures per applicable shop safety standards. Use the correct torx or hex key to the cutter body manufacturer's specified procedure when seating the screw-clamp. Inspect the insert pocket and seating surface for chips or debris before installing the new insert to ensure proper seating and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SDPT\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: KCPM20\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, MT-TiCN, Al2O3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed T-Land\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: 0.5 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: 0.0313 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material (ISO P, M, K, H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 3957966\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728723673394,"sku":"3957966","price":39.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee31f81689dd36d1b4463ca84d6c847c.jpg?v=1788695505","url":"https:\/\/voomisupply.com\/products\/kennametal-3957966-milling-insert-kcpm20-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
