Manufactured to the TD6P1 insert style in grade HP520B, it features a 60-degree triangular shape with a physical vapor deposition (PVD) TiN coating for improved wear resistance and heat dissipation. The insert measures 3\/8 inches inscribed circle and 1\/8 inches thick, with a corner radius of 1\/64 inches (0.0150 inches) and an 11-degree relief angle. It is secured with a screw-type holding method, making it compatible with standard TD6P toolholders. Licensed machinists and toolroom professionals install this insert in CNC boring bars and internal turning setups.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finish and semi-finish boring of steel and cast iron workpieces where tight tolerances and consistent surface finish are required. The C5 material grade and TiN coating make it a practical choice for general-purpose machining at moderate cutting speeds. It is sold individually per package with a minimum order quantity of 10 units, making it appropriate for shop floor replenishment or toolcrib stocking. Typical applications include line boring, housing bores, and sleeve fitting operations in both production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade C5 for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiN coating applied via PVD process for extended tool life and reduced friction\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular shape (TD6P1 style) provides multiple usable cutting edges\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch corner radius (0.0150 inches) suited for tight-radius finish boring\u003c\/li\u003e\n  \u003cli\u003e11-degree relief angle reduces rubbing and improves clearance in bore entry\u003c\/li\u003e\n  \u003cli\u003eScrew-type clamping method for positive, repeatable insert indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-clamp TD6P-style boring bars and toolholders that accept a triangular insert with a 3\/8-inch inscribed circle and 0.1300-inch hole diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the machine is locked out before indexing or replacing inserts. Use the correct torque screwdriver or T-key specified by the toolholder manufacturer to seat the clamping screw  -  avoid overtightening, which can fracture the carbide. Inspect the insert pocket and seating surface for chips or debris before installing a fresh insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TD6P1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HP520B\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: C5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Triangle (60-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inches (0.1270 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 0.03 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H59875054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743287542066,"sku":"H59875054","price":302.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4f11e8792bf0afbb7651cadf6ff8815.jpg?v=1788845108","url":"https:\/\/voomisupply.com\/products\/hertel-h59875054-boring-insert-td6p1-hp520b-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
