It features a triangular insert shape with a 60-degree included angle, a 3\/8-inch inscribed circle, and a 1\/32-inch corner radius. The 4425 carbide grade is applied with a CVD-deposited multilayer coating of Al2O3, TiCN, and TiN, delivering wear resistance and thermal stability at elevated cutting speeds. The QM chip breaker geometry controls chip flow across a range of feed rates and depths of cut. This insert is installed by licensed machinists and CNC operators in production turning environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel and cast iron workpieces in both roughing and finishing applications. The neutral hand orientation makes it compatible with standard TNMG-style toolholders used in right-hand and left-hand turning configurations. It belongs to the T-Max P series, which is optimized for steel turning under stable conditions. Typical applications include shaft turning, facing, and profiling on medium-to-large CNC lathes in production and job-shop settings. The insert uses a clamp and screw holding method, consistent with standard ISO indexable toolholder systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-coated carbide with Al2O3, TiCN, and TiN multilayer coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eTNMG332-QM geometry with QM chip breaker for effective chip control across varied feed rates\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular shape provides 6 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle and 1\/32-inch corner radius for standard TNMG toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eNeutral hand — compatible with right-hand and left-hand TNMG toolholders\u003c\/li\u003e\n  \u003cli\u003ePrimary workpiece material: Steel (ISO P); secondary: Cast Iron (ISO K)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit indexable replacement for standard TNMG 16 04 08 style toolholders using a clamp and screw holding method.

Power down and lock out the machine spindle before indexing or replacing the insert. Use the correct torque-limiting screwdriver or clamp tool as specified by the toolholder manufacturer — do not overtighten the clamping screw. Inspect the toolholder seat and clamping surfaces for chips or debris before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\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\u003eManufacturer Grade\u003c\/strong\u003e: 4425\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: Al2O3, TiCN, TiN (CVD process)\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\/32 inch (0.0313 inch \/ 0.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inch (3.81 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: QM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG 16 04 08-QM 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 x 1.54 x 0.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7861099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749585223986,"sku":"7861099","price":244.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/668a2aa62066ebdb56adda52a4aae826_250ca67f-1d63-4d34-a37e-0cd2989ffccf.jpg?v=1788907964","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861099-tnmg332-qm-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
