It features a 60-degree triangular shape with a neutral hand orientation and a 1\/32-inch corner radius, making it suitable for general-purpose external and internal turning operations. The insert measures 0.65 inches in length with a 3\/8-inch inscribed circle and a 3\/16-inch thickness. It is held in place by clamp or pin toolholders and is installed by machinists and CNC lathe operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on steel and stainless steel workpiece materials, corresponding to ISO P and M material groups and ANSI C5 and C6 material grades. The G-style chip breaker geometry supports controlled chip formation across a range of feed rates and depths of cut typical in finish and semi-finish turning passes. It fits standard TNMG-style toolholders commonly used on manual lathes and CNC turning centers in both production and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHC335 grade solid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating\u003c\/li\u003e\n\u003cli\u003eTNMG332 insert style with 60-degree triangular shape and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003e1\/32-inch (0.0313 inch) corner radius for semi-finish and finish turning applications\u003c\/li\u003e\n\u003cli\u003eG-style chip breaker for controlled chip evacuation on steel and stainless workpieces\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin holding methods in standard TNMG toolholders\u003c\/li\u003e\n\u003cli\u003eClearance code N and tolerance code M for consistent, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard indexable insert for TNMG-style toolholders accepting 332-size triangle inserts with a 0.150-inch hole diameter and clamp or pin holding methods.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using standard insert clamp screws or retaining pins appropriate for the toolholder design. Ensure the machine spindle is fully stopped and the turret is locked before indexing or replacing inserts. Use proper insert handling practices to avoid edge chipping prior to installation. Verify toolholder pocket seating surfaces are clean and free of chips before securing the insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG332R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC335\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 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 Length\u003c\/strong\u003e: 0.65 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\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\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: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: P (Steel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: M (Stainless Steel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1000272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739237777714,"sku":"1000272","price":277.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc84abdb130645e82ab3aebb34b8e535.jpg?v=1788811909","url":"https:\/\/voomisupply.com\/products\/hertel-1000272-tnmg332r-hc335-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
