It features a 35-degree diamond (rhombic) shape with a neutral hand orientation and a negative rake and side clearance geometry. The GH330 grade carries a TiCNO PVD coating engineered for high wear resistance with balanced toughness. With a 1\/64 inch (0.0157 inch) corner radius and a honed cutting edge, this insert is optimized for finishing operations. It provides four usable cutting edges per insert and is held in place by a clamp and pin system.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, boring, back turning, and back boring of steel, stainless steel, and cast iron workpieces, corresponding to ISO material classifications P, M, and K. Applicable material grades include P15, P30, M15, M30, K05, and K30. It suits a wide range of production turning applications where consistent surface finish and dimensional accuracy are required. Machinists and CNC operators working in job shop or production environments will find this insert a direct fit for compatible VNMG toolholders. Standards compliance covers both ANSI and ISO specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGH330 grade with TiCNO PVD coating for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (rhombic) insert shape with negative rake for stable finishing cuts\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert maximizes tool life per unit\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style supports consistent surface finish in finishing chip breaker applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods for secure seating in toolholders\u003c\/li\u003e\n  \u003cli\u003eDual ANSI and ISO standard compliance for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VNMG-style toolholders that accept a 331 (ISO 160404) size insert with clamp and pin holding.

Always index or replace inserts with the machine powered down and the spindle fully stopped. Use appropriate insert seating tools to ensure the insert is fully seated against all pocket surfaces before clamping. Inspect the toolholder pocket and locating pin for wear or debris prior to seating a new insert, as pocket damage will affect runout and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMG331SS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMG160404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: GH330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCNO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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 Material\u003c\/strong\u003e: Carbide\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: 1.308 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\u003eWidth\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1181 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: SS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grades\u003c\/strong\u003e: P15, P30, M15, M30, K05, K30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Size Code\u003c\/strong\u003e: 331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Size Code\u003c\/strong\u003e: 160404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VNMG-SS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6809441\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972272193842,"sku":"6809441","price":278.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd20b74cd50c561d8528520de791a2d6.jpg?v=1789965422","url":"https:\/\/voomisupply.com\/products\/tungaloy-6809441-vnmg331ss-gh330-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
