This uncoated, neutral-hand insert features a 60-degree triangular shape with an inscribed circle of 0.375 inches and a corner radius of 0.004 inches. At 0.65 inches in length and 0.125 inches thick, it fits standard TPG-style clamp-type toolholders. Manufactured to HT10 grade solid carbide, it delivers consistent edge geometry on non-ferrous, stainless, and cast material applications. It is part of the KENDEX series and carries a G tolerance code with P clearance code.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for precision turning in light-to-moderate cutting conditions. It is commonly used in job shops and production environments where tight tolerances and sharp edge geometry are required. The neutral hand orientation allows use in both right-hand and left-hand toolholder setups depending on application. Workpiece material compatibility includes non-ferrous metals (N), superalloys (S), cast iron (K), and non-ferrous alloys (M). Maximum depth of cut is 0.049 inches (1.25 mm), making it appropriate for finishing and light semi-finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide, uncoated HT10 grade for sharp, consistent edge retention\u003c\/li\u003e\n  \u003cli\u003eTPG320 style with 60-degree triangular insert shape and insert size code 320\u003c\/li\u003e\n  \u003cli\u003e0.004 inch corner radius for fine-finish turning applications\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method with G tolerance and P clearance codes\u003c\/li\u003e\n  \u003cli\u003eKENDEX series, C2 material grade, no chip breaker\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for TPG-style clamp-type turning toolholders accepting a 3\/8 inch inscribed circle triangular insert in the TPG320 configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is properly secured before seating or replacing the insert. Use the correct clamp torque specified by the toolholder manufacturer to avoid insert fracture or movement during cut. Inspect the toolholder pocket and clamp for wear or damage before installing a 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: TPG320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.049 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: N, S (Non-Ferrous, Superalloys)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: K, M (Cast Iron, Non-Ferrous Alloys)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1000681\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755611849010,"sku":"1000681","price":208.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c504d618bd00d1ef915fb7eacd91f7c9.jpg?v=1788956887","url":"https:\/\/voomisupply.com\/products\/hertel-1000681-tpg320-ht10-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
