It carries a multilayer CVD coating of TiC, TiCN, and TiN under the KC850 grade designation, which is engineered for moderate wear resistance and toughness across a broad range of workpiece materials. The insert measures 22 millimeters (0.866 inches) in length with a 0.5-inch inscribed circle and a 3\/16-inch thickness. The triangular shape provides three usable cutting edges, and the neutral hand orientation suits standard right-hand or left-hand toolholders configured for TPG-style clamping.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, and cast iron, as well as select special and super alloys. The flat-top chip breaker geometry and positive rake angle support stable chip control at moderate to aggressive material removal rates. It is appropriate for use in production turning centers and manual lathes in industrial, job shop, and maintenance environments. Licensed machinists and CNC operators are the primary installers. Maximum depth of cut is 1.25 millimeters (0.049 inches).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade with CVD multilayer TiC, TiCN, TiN coating for extended tool life on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eTriangle insert shape (60-degree included angle) with 3 cutting edges for economical edge utilization\u003c\/li\u003e\n\u003cli\u003eFlat-top chip breaker with positive rake angle for stable chip evacuation\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces micro-chipping on interrupted and continuous cuts\u003c\/li\u003e\n\u003cli\u003eClamp-held insert design compatible with standard TPG-style toolholders\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for flexible toolholder setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specified replacement or direct-use insert for KENNAMETAL KENDEX-series TPG-style toolholders accepting ANSI insert code TPG431 (ISO equivalent TPG220404).

Use the appropriate torque wrench or insert-clamping tool specified for the toolholder model to secure the clamp screw — do not overtighten by hand. Inspect the insert pocket seat and clamping components for wear or debris before seating a new insert. Verify depth-of-cut and feed rate parameters are within the published range for the KC850 grade before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPG220404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN (CVD Multilayer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 22 millimeters (0.866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 millimeters (0.049 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive side clearance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Special and Super Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 1183317\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748207362354,"sku":"1183317","price":265.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea25d1b1c781c20d8fe6ac9b06cb8e75.jpg?v=1788890347","url":"https:\/\/voomisupply.com\/products\/kennametal-1183317-tpg431-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
