It features a square insert shape with a 90-degree included angle, a left-hand orientation, and a GB2 chip breaker geometry. The tri-layer PVD coating  -  TiN, TiCN, TiN  -  provides wear resistance and thermal stability during interrupted and continuous milling operations. At 0.1875 inches thick with a 0.5000-inch inscribed circle and a 0.0315-inch corner radius, this insert suits precision milling applications where tight tolerances and surface finish consistency are required. Screw-style insert holding provides secure clamping under high cutting forces.\u003c\/p\u003e\u003cp\u003eThis insert is designed for milling steel, stainless steel, superalloys, and titanium  -  workpiece material codes P, M, and S per ISO classification. It fits applications ranging from general-purpose steel roughing to demanding cuts in aerospace-grade titanium and nickel-base superalloys. The KC725M grade with PVD TiN\/TiCN\/TiN coating is suited for moderate to high cutting speeds where edge toughness and coating adhesion are critical. Typical install scenarios include face milling, shoulder milling, and helical interpolation on CNC machining centers. The left-hand designation must be matched to the correct hand of the cutter body during setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eISO designation SDET1204PDELGB2 with GB2 chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eKC725M grade with PVD tri-layer TiN\/TiCN\/TiN coating for wear resistance and edge stability\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle and 15-degree relief angle\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation  -  must be matched to a compatible left-hand cutter body\u003c\/li\u003e\n\u003cli\u003e0.0315-inch (0.80 mm) corner radius for balanced edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eScrew-mount insert holding method for positive, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use insert for SDET-series left-hand milling cutter bodies accepting a 1\/2-inch inscribed circle, 3\/16-inch thick square insert with screw holding.

Power down and lock out the spindle before seating or removing inserts. Use the correct torx or hex key torque driver specified by the cutter body manufacturer  -  do not overtighten or undertighten the clamping screw. Verify insert seating in the pocket is flush and fully supported before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SDET1204PDELGB2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GB2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\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: 0.5000 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: 0.0315 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: 0.0163 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: 2390284\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51990571221298,"sku":"2390284","price":215.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4c3cc5992fa0e6dc22091be70c64402.jpg?v=1789989041","url":"https:\/\/voomisupply.com\/products\/kennametal-2390284-milling-insert-kc725m-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
