Built to insert style TDHB with a 60-degree triangular geometry, this uncoated insert carries manufacturer grade HT510B and material grade C4. The inscribed circle measures 5\/32 inches (0.1600 inches decimal), thickness is 3\/64 inches (0.0469 inches decimal), and the corner radius is 0.007 inches. The 15-degree relief angle supports clearance in tight bore profiles. It is held in place by a screw-clamping method, making it a standard fit for compatible boring bars used by machinists and tooling professionals in production and maintenance machining environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for boring and internal turning applications where a triangular, positive-relief geometry is required. The solid carbide construction and C4 material grade make it appropriate for finishing and semi-finishing passes on ferrous and non-ferrous materials. The uncoated surface is typical for applications where a coated insert may cause dimensional interference or where cutting fluid-based lubrication is the primary wear management strategy. Packaged individually, this insert is sold with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60-degree triangular insert geometry (TDHB style) for boring and internal turning\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction, material grade C4, manufacturer grade HT510B\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for finishing and semi-finishing operations\u003c\/li\u003e\n\u003cli\u003e0.007-inch corner radius for controlled edge geometry on bore surfaces\u003c\/li\u003e\n\u003cli\u003e15-degree relief angle provides clearance in confined bore profiles\u003c\/li\u003e\n\u003cli\u003eScrew-clamping insert holding method for positive, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit boring insert for screw-clamp boring bars and holders accepting TDHB-style triangular inserts with a 5\/32-inch inscribed circle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement of boring inserts should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the correct torque driver for the clamping screw to avoid insert fracture or seat damage. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TDHB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1.280.75.0.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT510B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/32 inches (0.1600 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/64 inches (0.0469 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.007 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 1.5 inches W x 0.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: H59873406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753375269170,"sku":"H59873406","price":287.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8fd1ee3858c24d9e5b0723506b9684a9.jpg?v=1788935968","url":"https:\/\/voomisupply.com\/products\/hertel-h59873406-boring-insert-triangle-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
