It carries a 35-degree diamond (rhombic) shape, a neutral hand orientation, and a 1\/64-inch corner radius suited for finishing operations. The insert measures 16.61 mm (approximately 0.654 inches) in length with a 3\/8-inch inscribed circle and a 3\/16-inch thickness. Four cutting edges are available per insert. It is installed by machinists and toolroom technicians in CNC turning centers and manual lathes using clamp or pin holding methods.\u003c\/p\u003e\u003cp\u003eThis insert is designed for finishing passes on steel, stainless steel, and cast iron workpieces, corresponding to ISO material groups P, M, and K. Its FP chip breaker geometry controls chip flow during light-to-moderate finishing cuts, with a maximum depth of cut of 0.0492 inches (1.25 mm). Typical applications include turning, facing, boring, back turning, and back boring operations. The KT315 cermet grade delivers high wear resistance across all three primary workpiece material categories, making it well suited for production environments where consistent surface finish and dimensional accuracy are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKT315 cermet grade with multilayer PVD TiN\/TiCN\/TiN coating for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eFP chip breaker optimized for finishing operations with controlled chip flow\u003c\/li\u003e\n\u003cli\u003e35-degree diamond (rhombic) insert shape provides a sharp, low-cutting-force geometry\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for extended tool life\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI insert code VNMG331 and ISO insert code VNMG160404\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC series toolholders accepting VNMG331 or VNMG160404 geometry inserts with clamp or pin clamping.

Use the appropriate torque wrench and seating tool specified by the toolholder manufacturer to seat the insert without rocking or forcing. Inspect the insert pocket and seating surfaces for chips or debris before seating a new insert edge. Follow facility lockout\/tagout procedures before accessing the cutting zone.\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\u003eIndustry Standard Number\u003c\/strong\u003e: VNMG331FP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KT315\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN \/ TiCN \/ TiN (Multilayer 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\u003eChip Breaker\u003c\/strong\u003e: FP (Finishing)\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 inch (0.3750 inches)\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 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: 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\u003eRake Angle\u003c\/strong\u003e: 15 degrees (Negative)\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\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 Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C7\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: 0.0104 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: 1819357\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754610131250,"sku":"1819357","price":203.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d90d4b5fe24f09c8015b961bb307c1fc.jpg?v=1788947094","url":"https:\/\/voomisupply.com\/products\/kennametal-1819357-turning-insert-vnmg331fp-kt315-cermet","provider":"Voomi Supply","version":"1.0","type":"link"}
