The insert features a 60-degree triangular geometry with an 11-degree relief angle and a 1\/32-inch corner radius, making it suitable for controlled, repeatable cuts in ferrous and non-ferrous materials. The HP520B grade carbide substrate carries a TiN coating applied via PVD process, which extends cutting edge life and reduces built-up edge at moderate cutting speeds. This insert is held in the toolholder by a screw-clamp method and is selected by machinists, tool-and-die technicians, and CNC operators for boring applications requiring tight tolerances.\u003c\/p\u003e\n\u003cp\u003eThis insert is appropriate for use in screw-lock boring bars and toolholders designed to accept the TD6P insert style. With a 3\/8-inch inscribed circle and 1\/8-inch thickness, it fits compact boring heads used in both production and repair-shop environments. The C5 material grade designation makes it well suited for general-purpose machining of cast iron, steel, and similar workpiece materials at medium cutting parameters. Applications include internal diameter finishing and light roughing passes on lathes and machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiN coating for extended edge life\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape with 11-degree relief angle for positive cutting action\u003c\/li\u003e\n  \u003cli\u003e1\/32-inch corner radius (0.0310 inches decimal) for controlled surface finish\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (0.3750 inches) fits standard compact boring bar pockets\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eHP520B manufacturer grade, C5 material grade for general-purpose ferrous and non-ferrous machining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-lock toolholders and boring bars that accept the TD6P2 insert style 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\u003eInsert installation and replacement should be performed with the machine fully powered down and the spindle locked. Use the correct torque wrench and manufacturer-specified insert screw to secure the insert in the pocket  -  overtightening the clamp screw can fracture carbide inserts. Inspect the insert pocket seat for chips or debris before seating a new insert. Worn or damaged inserts should be indexed or replaced before resuming cuts to avoid workpiece damage or toolholder failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TD6P2\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HP520B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\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\/32 inches (0.0310 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\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\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: H59875179\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743032869170,"sku":"H59875179","price":293.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e623fb91a4d358bb98459ae4f4c47be.jpg?v=1788841802","url":"https:\/\/voomisupply.com\/products\/hertel-h59875179-boring-insert-td6p2-hp520b-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
