It features a 35-degree diamond (rhombic) insert shape with a neutral hand orientation and a flat-top chip breaker. The inscribed circle measures 3\/8 inches, insert length is approximately 1.308 inches (16.61 mm), and the corner radius is 1\/64 inches. Grade K68 is formulated for high wear-resistance to moderate wear-resistance and toughness across stainless steel, cast iron, aluminum, and non-ferrous materials. With four available cutting edges, this insert delivers extended tool life in production turning environments. Licensed machinists and CNC operators in metal fabrication and precision machining shops are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is suited for a broad range of turning operations including turning, facing, boring, back turning, and back boring. It performs on non-ferrous metals, superalloys, titanium, stainless steel, and cast iron workpieces, covering ISO material groups P, M, K, N, and S. The VNGA geometry with negative rake and negative side clearance makes it compatible with rigid, negative-style toolholders used in high-production and medium-duty CNC lathe applications. The flat-top chip breaker geometry is best matched to applications requiring consistent chip control without a molded breaker profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e35-degree diamond (rhombic) insert shape — ANSI code VNGA331, ISO code VNGA160404\u003c\/li\u003e\n\u003cli\u003eGrade K68 solid carbide, uncoated (bright finish) — high wear-resistance across K, M, N, and S material groups\u003c\/li\u003e\n\u003cli\u003eFour cutting edges with honed cutting edge style for extended service life\u003c\/li\u003e\n\u003cli\u003eFlat-top chip breaker with negative rake and 0-degree relief angle\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 0.049 inches (1.25 mm); inscribed circle 3\/8 inches; corner radius 1\/64 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series negative-style turning toolholders accepting VNGA331 geometry inserts.

Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamping hardware specified by the toolholder manufacturer — do not substitute hardware. Inspect the toolholder seat and clamping components for wear or damage each time the insert is indexed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNGA331\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNGA160404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K68\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\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.308 inches (16.61 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 3\/8 inches (0.375 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\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches (3.81 mm)\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp; Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal; Superalloys and Titanium; Stainless Steel; Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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: 0.026 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: 1160077\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734266708274,"sku":"1160077","price":216.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdb9ed6c5a7e2ef33dcbf37c387d9712.jpg?v=1788761825","url":"https:\/\/voomisupply.com\/products\/kennametal-1160077-vnga331-k68-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
