It features a 35-degree diamond (rhombic) shape, a neutral hand orientation, and a positive rake and side clearance geometry suited for finishing and light machining operations. The insert measures 16.61 mm in length with a 3\/8-inch inscribed circle and a 0.0039-inch corner radius. It uses a screw-on holding method and delivers two cutting edges per insert. Licensed HVAC and metalworking machinists, CNC turning center operators, and tool-crib technicians specify this insert for tight-tolerance external and internal turning passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, boring, back turning, and back boring applications. The KC5025 grade with TiAlN PVD coating is rated for moderate wear-resistance and toughness across steel (P), stainless steel (M), cast iron (K), and aluminum and non-ferrous (N) workpiece materials, with a primary suitability designation for stainless steel and superalloys and titanium (S). Maximum depth of cut is 1.25 mm (0.0492 inches). The LF chip breaker geometry supports light chip loads and finishing surface quality requirements on precision components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVBGT 35-degree diamond shape with positive rake and positive side clearance for low cutting forces\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating on KC5025 carbide substrate — moderate wear-resistance and toughness balance\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker optimized for finishing and light machining chip control\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert for extended tool-crib value\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method for rigid, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces edge microchipping on difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI (VBGT3302) and ISO (VBGT160401) insert coding standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on VBGT-style turning toolholders conforming to ANSI insert code VBGT3302 and ISO insert code VBGT160401.

Use the correct screw-torque driver specified by the toolholder manufacturer — do not overtighten the screw-on fastener, as carbide inserts are brittle and will crack under excess clamping force. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Always verify insert orientation matches the neutral-hand designation of the toolholder before resuming cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VBGT3302\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VBGT160401\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: VBGT3302LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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\u003eIncluded Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing, Light Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 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: 0.0039 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Material Codes\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back Boring\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: 0.022 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 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: 1866681\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728736780594,"sku":"1866681","price":255.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3895c2bbf157bc9698f13fa3a02d8b62.jpg?v=1788695632","url":"https:\/\/voomisupply.com\/products\/kennametal-1866681-turning-insert-vbgt330lf-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
