It carries the ANSI insert designation VBMT331LF and ISO designation VBMT160404. The insert is manufactured with a CVD-applied multilayer coating of TiC, TiCN, and TiN under the proprietary KC850 grade, which delivers moderate wear resistance combined with toughness for steel, stainless steel, and cast iron workpieces. The LF chip breaker geometry is optimized for finishing and light machining passes. Licensed machinists and CNC operators working in production or maintenance turning will find this insert suited to tight-tolerance surface finish requirements.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for finishing and light machining of steel (ISO P), stainless steel (ISO M), cast iron (ISO K), and special or super alloys (ISO S) in both industrial and job-shop environments. The positive rake and positive side clearance reduce cutting forces, making it a practical choice for thin-wall components, small-diameter bores, and back-turning operations where vibration control matters. The screw-on holding method provides repeatable seating in compatible toolholders with a standard 0.1732-inch hole diameter. Maximum recommended depth of cut is 1.25 mm (0.0492 inches), confirming its finishing-pass application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC850 grade CVD multilayer TiC\/TiCN\/TiN coating for wear resistance and toughness across ISO P, M, K, and S material groups\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry engineered for finishing and light machining passes\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (rhombic) V-shape insert with positive rake and positive side clearance to reduce cutting forces\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method with 0.1732-inch hole diameter for secure, repeatable toolholder seating\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for improved edge stability on difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; neutral hand for flexible application in standard toolholder setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on VBMT-style toolholders conforming to ANSI and ISO standards.

Ensure the machine spindle is fully stopped and the toolholder is removed or the turret is locked before seating or replacing the insert. Use the appropriate torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque — do not overtighten, as carbide inserts are brittle and will crack under excess clamping force. Inspect the insert pocket and seating surface for chips or debris before mounting to maintain accurate insert positioning and surface finish results.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VBMT331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VBMT160404\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 (CVD Multilayer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide (C5, C6)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF - Finishing and Light Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.61 mm (0.6537 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: 1\/64 inch (0.0156 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\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0198 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package; minimum order quantity of 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: 1162402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51752910389554,"sku":"1162402","price":222.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0314f51fa3caa97aee1c60944a1b2d2d.jpg?v=1788931018","url":"https:\/\/voomisupply.com\/products\/kennametal-1162402-vbmt331lf-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
