Built from solid carbide with a multilayer CVD coating of TiC, TiCN, and TiN, this insert delivers a combination of wear resistance and toughness suited to interrupted and continuous cuts. The 35-degree diamond (rhombic) insert shape provides a sharp approach angle for profiling and finishing work. With a 3\/8-inch inscribed circle, a 3\/16-inch thickness, and a 1\/64-inch corner radius, it fits KENLOC-style toolholders and similar negative-rake clamping systems. Four usable cutting edges per insert contribute to cost-effective tool management in production environments.\u003c\/p\u003e\u003cp\u003eThis insert is rated for steel (P), stainless steel (M), cast iron (K), and special or super alloys (S) at moderate wear-resistance and toughness to high-toughness cutting conditions. Typical applications include turning, facing, boring, back turning, and back boring on general-purpose and high-production lathes. The medium-machining chip breaker geometry handles a range of depths of cut up to approximately 0.05 inches (1.25 mm), making it a practical choice for roughing-to-finishing transitions. It is well suited to job shops, aerospace component machining, and automotive production lines where consistent tool life across varied workpiece materials is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade with multilayer CVD TiC\/TiCN\/TiN coating for wear resistance across steel and stainless applications\u003c\/li\u003e\n\u003cli\u003e35-degree V-diamond insert shape (VNMG) for profiling, contouring, and facing operations\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eMedium-machining chip breaker supports turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003cli\u003eNegative rake, negative side clearance geometry compatible with KENLOC clamp-and-pin toolholders\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO dimensional standards (ANSI: VNMG331, ISO: VNMG160404)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-style and other negative-rake toolholders accepting VNMG-style inserts with a 3\/8-inch inscribed circle and clamp-or-pin insert holding.

Power down and de-energize the machine tool before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert. Inspect the toolholder pocket and clamp for wear or damage before seating a new insert to ensure proper clamping force and accurate edge positioning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMG331\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMG160404\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: KC850\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.61 mm (1.3076 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inch (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 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\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Medium Machining (Common)\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 (P), Stainless Steel (M), Cast Iron (K), Special and Super Alloys (S)\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0201 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\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: 1160340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731766608178,"sku":"1160340","price":223.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d3f0894d1e2c5c55b4fb7b897434f13.jpg?v=1788734709","url":"https:\/\/voomisupply.com\/products\/kennametal-1160340-vnmg331p-kc850-turning-insert-3-8-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
