The insert features a 60-degree triangular shape with a neutral hand orientation and a 3\/32-inch corner radius. At 1.299 inches in length with a 3\/4-inch inscribed circle and 3\/8-inch thickness, this insert is sized for medium-to-heavy turning operations. It is intended for use by machinists and CNC lathe operators working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning applications involving steel and stainless steel workpiece materials, corresponding to ISO material groups P and M. The TNMG style with G-type chip breaker geometry is commonly applied in continuous and semi-interrupted cuts at moderate to high feed rates. The HC335 grade and CVD multilayer coating provide wear resistance and thermal stability appropriate for these material groups. The insert is held using either a clamp or a pin-lock method, offering flexibility across a range of compatible toolholders. Each package contains one insert; the minimum order quantity is 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eTNMG666 style with 60-degree triangle insert shape and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003e3\/32-inch (0.0938-inch) corner radius for controlled surface finish on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eG-type chip breaker geometry suited for moderate to high feed turning\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin-lock holding methods for broad toolholder versatility\u003c\/li\u003e\n\u003cli\u003eClearance code N, tolerance code M for standard TNMG seat fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit indexable insert for TNMG-style toolholders accepting a 3\/4-inch inscribed circle, 3\/8-inch thickness, and 0.315-inch hole diameter.

Use the appropriate torx or hex key to secure the clamp or pin-lock per the toolholder manufacturer specifications. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: T\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.299 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.750 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.315 inches\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\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0026 pounds\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: 1000293\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728254861618,"sku":"1000293","price":760.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94e9ab4a0783150d4a890f46d77f4d0b.jpg?v=1788690095","url":"https:\/\/voomisupply.com\/products\/hertel-1000293-tnmg666r-hc335-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
