It features a 60-degree triangle (TDHB) geometry with a TiN coating applied via PVD process, providing wear resistance on ferrous materials. The insert measures 5\/32 inches inscribed circle with a 0.007 inch corner radius and a thickness of 0.0469 inches (3\/64 inches). Rated at material grade C5 with a 15-degree relief angle, this insert is suited for finishing and semi-finishing passes in metal boring applications. Installation is screw-held. It is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in boring bars and insert toolholders that accept the TDHB style seating. It is applicable in machine shop environments performing precision bore finishing on steel, cast iron, and similar ferrous workpieces. The HP520B manufacturer grade and PVD TiN coating make it a fit for production environments where consistent surface finish and dimensional accuracy are required. Machinists and CNC operators in job shops, production facilities, and toolrooms are the primary installers of this insert type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction at material grade C5 for rigidity and wear life\u003c\/li\u003e\n\u003cli\u003eTiN coating via PVD process for improved surface hardness and reduced built-up edge\u003c\/li\u003e\n\u003cli\u003e60-degree triangle shape (TDHB) with 15-degree relief angle for clearance in tight bores\u003c\/li\u003e\n\u003cli\u003e0.007 inch corner radius for fine finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-held insert mounting for positive clamping in compatible boring bar pockets\u003c\/li\u003e\n\u003cli\u003eCompact geometry: 5\/32 inch inscribed circle, 0.0469 inch thickness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in boring bars and toolholders configured for TDHB-style triangle inserts with a 5\/32 inch inscribed circle and screw-held clamping.

Ensure the machine spindle is fully stopped and the tool turret or boring bar is secured before changing inserts. Use the correct torque-limiting screwdriver or hex key specified by the toolholder manufacturer to seat the clamping screw  -  do not overtighten, as solid carbide inserts are brittle and can crack under excessive clamping force. Inspect the insert pocket for chips 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\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\u003eMaterial Grade\u003c\/strong\u003e: C5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HP520B\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: 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\u003eRelief Angle\u003c\/strong\u003e: 15 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 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\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: H59873372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739484782898,"sku":"H59873372","price":308.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/654f590b6b3a208c08349a9240229c8f.jpg?v=1788815112","url":"https:\/\/voomisupply.com\/products\/hertel-h59873372-boring-insert-triangle-tin-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
