Sized with a 0.5-inch inscribed circle and a 1\/64-inch (0.0156-inch) corner radius, it features an 80-degree diamond shape and a negative rake, negative side clearance configuration. Four usable cutting edges maximize tool life per insert. The K68 grade is an uncoated carbide formulated for high wear resistance across stainless steel, cast iron, aluminum, and other non-ferrous and superalloy materials. Chip breaker geometry is rated for medium machining operations. This insert is part of the KENNAMETAL KENLOC series and conforms to ANSI and ISO standards.\u003c\/p\u003e\u003cp\u003eSuitable for turning, facing, and boring operations in both production and job-shop environments. The CNMG431 geometry is a common choice for machining non-ferrous metals, cast iron, stainless steel, and superalloys including titanium where a sharp, wear-resistant uncoated edge is preferred over coated alternatives. The insert seats via clamp and pin holding methods, making it compatible with standard KENLOC-style toolholders. Maximum depth of cut is 0.049 inches (1.25 mm), placing this insert in light-to-medium finishing and semi-finishing applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCNMG431 geometry: 80-degree diamond shape with negative rake and negative side clearance for rigid, stable cutting\u003c\/li\u003e\n\u003cli\u003eK68 uncoated carbide grade with high wear resistance suited to stainless steel (M), cast iron (K), aluminum and non-ferrous (N), and superalloys and titanium (S)\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style balances sharpness with edge strength\u003c\/li\u003e\n\u003cli\u003eMedium machining chip breaker for predictable chip control in semi-finishing cuts\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards (ANSI CNMG431 \/ ISO CNMG120404) for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting CNMG431 (ISO CNMG120404) inserts with clamp and pin clamping.

Disconnect and lock out all machine power before seating or replacing inserts. Ensure the insert pocket and seating surfaces are clean and free of chips before clamping. Use the appropriate torque driver for the clamping screw to avoid insert fracture or improper seating — do not over-torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80-Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\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\u003eInsert Length\u003c\/strong\u003e: 0.5077 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.049 inches (1.25 mm)\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\u003eSide Clearance\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Common (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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Non-Ferrous Metal, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\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\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.054 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: 1160018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746376876338,"sku":"1160018","price":160.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e0a8b2a1c0767b0d2eb9307a71fc1d7.jpg?v=1788869194","url":"https:\/\/voomisupply.com\/products\/kennametal-1160018-cnmg431-k68-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
