It carries a TP40 manufacturer grade with a multilayer CVD coating — TiC, TiCN, and TiN — applied over a carbide substrate to extend tool life in continuous and interrupted cuts. The insert features a 35-degree diamond shape, a 3\/8 inch inscribed circle, a 1\/64 inch corner radius (0.0157 inch), and a positive rake geometry with an F2 chip breaker. Two cutting edges are available per insert, and the cutting edge style is honed for consistent entry into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, back turning, and profiling operations. Its primary workpiece materials are steel and stainless steel, corresponding to ISO material codes P and M. The TP40 grade and multilayer CVD coating make it appropriate for moderate to heavy-duty cutting conditions where heat resistance and wear resistance are required. The neutral hand configuration allows use in standard right-hand and left-hand toolholders that accept VBMT-style inserts. It is commonly installed by machinists and tool-and-die professionals working in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTP40 grade multilayer CVD coating: TiC, TiCN, and TiN for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape (Shape Code V) with positive rake geometry\u003c\/li\u003e\n  \u003cli\u003eF2 chip breaker optimized for turning, facing, profiling, and back turning\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for consistent tool engagement and reduced chipping\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert for extended service life per unit\u003c\/li\u003e\n  \u003cli\u003eScrew-holding method compatible with standard VBMT insert pockets\u003c\/li\u003e\n  \u003cli\u003eConforms to both ANSI and ISO standards; ISO code VBMT160404-F2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders and boring bars with VBMT-style insert pockets.

Verify pocket geometry and clamping screw size against the toolholder specification before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Before changing inserts, ensure the machine spindle is fully stopped and all motion is locked out per facility lockout\/tagout procedures. Seat the insert fully into the pocket and tighten the clamping screw to the toolholder specification — do not overtighten, as carbide inserts are brittle and can crack under excessive clamp force. Inspect the insert pocket for chips or debris before seating a new insert to maintain accurate tool geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VBMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VBMT-F2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: VBMT331-F2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VBMT160404-F2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 35 (Shape Code V)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P40, M35, M40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC, TiCN, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProprietary Coating Designation\u003c\/strong\u003e: Multilayer Coating\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\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.3078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1772 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.6142 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\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: F2\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Back Turning, Facing, Profiling, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 10\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74003926\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558905250098,"sku":"74003926","price":313.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f918893f936e27a06c1fedc7efedfae.jpg?v=1786422403","url":"https:\/\/voomisupply.com\/products\/seco-74003926-turning-insert-vbmt331-f2-tp40-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
