It features an 80-degree diamond (rhombic) insert shape with a neutral hand orientation, a 3\/4-inch inscribed circle, and a 3\/64-inch corner radius. The insert carries grade K68, which delivers high to moderate wear resistance and toughness across stainless steel, cast iron, aluminum, and non-ferrous workpiece materials. With 4 cutting edges, a negative rake, and a negative side clearance, this insert is designed for medium machining chip breaker operations. It is suitable for use by machinists and tooling technicians running CNC or manual turning equipment.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on non-ferrous metals, superalloys, titanium, stainless steel, and cast iron. It conforms to both ANSI and ISO standards, with an ANSI insert code of CNMG643 and an ISO insert code of CNMG190612. The KENLOC series clamping system uses a clamp-and-pin holding method, making it compatible with KENLOC-style toolholders designed for CNMG insert geometry. The common chip breaker profile handles a broad range of medium-duty stock removal applications in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80-degree diamond insert shape with 4 usable cutting edges for extended tool life per insert\u003c\/li\u003e\n  \u003cli\u003eK68 grade: uncoated solid carbide with high wear resistance and toughness for stainless steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation allows use in both left- and right-hand toolholder setups\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method compatible with KENLOC-style toolholders\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for stable entry and reduced chipping\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO dimensional standards for predictable drop-in replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series CNMG643 toolholders.

Power down and lock out the machine spindle before seating or replacing inserts. Secure the insert using the clamp-and-pin method per the toolholder manufacturer's torque and clamping procedure. Inspect the insert pocket and locating surfaces for chips or debris before seating a new insert to ensure proper contact and prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG643\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG190612\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K68\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: Uncoated (Bright)\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: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 19.34 mm (0.7616 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3125 inches (7.93 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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 Operation\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: Non-Ferrous Metal, Superalloys, Titanium, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\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: 0.0651 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: 1160025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727358132530,"sku":"1160025","price":294.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bf37a2ba0809366fcec56bd42ca1124.jpg?v=1788676687","url":"https:\/\/voomisupply.com\/products\/kennametal-1160025-cnmg643-k68-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
