Built from solid carbide and finished with a multilayer CVD coating sequence of TiC, TiCN, and TiN, this insert delivers a balance of wear resistance and toughness suited to interrupted and continuous cuts. The inscribed circle measures 0.5 inches, insert length is 0.8661 inches (22 millimeters), corner radius is 0.0625 inches (1\/16 inch), and insert thickness is 0.1875 inches (3\/16 inch). The neutral hand orientation and negative rake geometry make it a versatile choice across turning, facing, and boring operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in production and job-shop environments for machining steel, stainless steel, and cast iron workpieces, with rated applicability also extending to special and super alloys. The KC850 grade targets moderate wear-resistance and toughness across ISO material groups P, M, K, and S. Typical applications include general turning and medium machining passes where controlled chip breaking and edge stability are required. The KENLOC series designation indicates compatibility with pin-and-clamp style toolholders using the TNMG seating configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating (TiC, TiCN, TiN) for wear resistance and heat dissipation in steel and stainless steel cutting\u003c\/li\u003e\n  \u003cli\u003e6 cutting edges per insert from a 60-degree triangular shape, maximizing insert utilization\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge preparation reduces chipping at entry and exit\u003c\/li\u003e\n  \u003cli\u003eMedium machining chip breaker geometry controls chip flow across a range of feed rates and depths\u003c\/li\u003e\n  \u003cli\u003eNegative rake, negative side clearance geometry provides mechanical strength and longer edge life\u003c\/li\u003e\n  \u003cli\u003eCompatible with both clamp and pin insert holding methods for flexible toolholder pairing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TNMG-style toolholders within the KENNAMETAL KENLOC system, accepting inserts with clamp or pin holding. ANSI insert code TNMG434; ISO insert code TNMG220416. Suitable for turning, facing, and boring operations on steel, stainless steel, cast iron, and select superalloy workpieces per material grade codes P, M, K, and S.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed machinists or qualified tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Verify the toolholder pocket is clean and free of debris before inserting to ensure proper seating and prevent premature edge failure. Follow the toolholder manufacturer's torque specifications for the clamping screw or pin — do not overtighten, as carbide inserts are brittle and can crack under uneven clamping force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG434\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG220416\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN (Multilayer CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 0.8661 inches (22 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches (5.16 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\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\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\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\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0262 pounds\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: 1160305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737434685746,"sku":"1160305","price":197.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2307fcf3c7dde4077d209f293fa9158b.jpg?v=1788788517","url":"https:\/\/voomisupply.com\/products\/kennametal-1160305-tnmg434-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
