It carries the TP3501 manufacturer grade and features a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, delivering wear resistance and thermal stability during continuous and interrupted cuts. The insert has a 3\/8-inch inscribed circle, a 1\/64-inch corner radius, and a negative rake geometry with a chamfered and honed cutting edge. Six usable cutting edges are available per insert, and the M3 chip breaker geometry is suited for moderate feed and depth-of-cut conditions across a wide range of steel and stainless steel workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, boring, and back turning operations on CNC and manual lathes processing steel (ISO material group P) and stainless steel (ISO material group M), including P20, P30, and P40 material grades. It is held in toolholders using clamp, pin, or lever lock holding methods and fits standard TNMG-style pockets. The neutral hand designation makes it suitable for right-hand or left-hand applications depending on the toolholder. Typical users include CNC machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for extended tool life in steel machining\u003c\/li\u003e\n  \u003cli\u003eSix cutting edges per insert for maximized cost-per-edge value\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker geometry supports turning, facing, boring, and back turning\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style provides edge stability and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 60-degree triangular insert shape with 0 degree relief angle and N clearance code\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO standards; ISO code TNMG160404-M3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard TNMG-style toolholders accepting clamp, pin, or lever lock insert holding methods with a 0.1500-inch hole diameter.

Ensure the machine spindle is stopped and the turret or toolpost is fully locked out before seating or indexing the insert. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer; do not overtighten the clamping screw. Inspect the insert pocket for chips or debris before seating each new cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TNMG331-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG160404-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP3501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle, 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6496 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.6102 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P20, P30, P40)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\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: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 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: 03093878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559814037810,"sku":"03093878","price":224.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8db51e312dbc8a25ac6a668459baeb01.jpg?v=1786441805","url":"https:\/\/voomisupply.com\/products\/seco-03093878-tnmg331-m3-carbide-turning-insert-3-8-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
