It features a 35-degree diamond (rhombic) shape, a 3\/8-inch inscribed circle, and a 1\/64-inch corner radius. The insert carries the K68 grade, which delivers high wear resistance with moderate toughness for machining stainless steel, cast iron, aluminum, and non-ferrous materials. The bright, uncoated finish suits applications where coating buildup would be a concern. With four cutting edges and a negative rake angle, this insert is engineered for efficient stock removal in turning, facing, boring, back turning, and back boring operations. Licensed machinists and CNC operators in production and job-shop environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for medium machining operations on non-ferrous metals, superalloys, titanium, stainless steel, and cast iron. The VNMP geometry with a neutral hand orientation fits a range of standard KENLOC toolholders accepting the VNMP insert style. Typical applications include external and internal turning on CNC lathes and turning centers where precise chip control at moderate depths of cut is required. The maximum depth of cut is 1.25 mm (0.0492 inches), making it appropriate for finishing and light semi-finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e35-degree diamond (rhombic) insert shape for access in tight toolpath geometries\u003c\/li\u003e\n  \u003cli\u003eK68 grade with high wear resistance suited for stainless steel, cast iron, aluminum, and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated solid carbide construction eliminates coating-related edge buildup on non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003eNegative rake, negative side clearance design for rigid, stable cutting action\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO insert standards (ANSI: VNMP331, ISO: VNMP160404)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC series toolholders accepting VNMP-style inserts with a 3\/8-inch inscribed circle.

The machine spindle must be fully stopped and all axes locked before seating or indexing the insert. Secure the insert using the appropriate clamp or pin holding hardware specified for the toolholder, and verify seating before returning the tool to service. Do not exceed the rated maximum depth of cut for this geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMP331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMP160404\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\u003eManufacturer Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.61 mm (0.6534 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches (3.81 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees negative\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0218 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 5)\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: 1161201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733681537330,"sku":"1161201","price":189.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23a538485b005472a11de143f1fc64b9.jpg?v=1788758048","url":"https:\/\/voomisupply.com\/products\/kennametal-1161201-turning-insert-vnmp331k-k68-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
