Built to CDHH style with an 80-degree diamond shape, it features a Physical Vapor Deposition (PVD) TiN coating over a C5 carbide grade substrate, providing wear resistance and extended tool life in ferrous and non-ferrous materials. Key geometry specs include a 0.007 inch corner radius, a 5\/32 inch (0.1560 inch) inscribed circle, a 0.0400 inch thickness, and a 15-degree relief angle. This insert is screw-held and configured for left-hand cutting. It is installed by machinists and tool-room technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert suits light to medium-duty boring applications where tight tolerances and surface finish are priorities. The CDHH style and 80-degree included angle make it effective for general-purpose turning and boring passes in steel, cast iron, and similar workpiece materials. The left-hand configuration is required for specific toolholder orientations where conventional right-hand inserts cannot be used. It is sold individually but requires a minimum order quantity of 10 units, making it appropriate for shop stock replenishment and toolcrib management.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCDHH insert style with 80-degree diamond geometry for general boring and turning applications\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating over C5 solid carbide substrate for wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003e0.007 inch corner radius suitable for finish and semi-finish boring passes\u003c\/li\u003e\n  \u003cli\u003e15-degree relief angle reduces rubbing and improves tool clearance in bore entry\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting configuration for compatible left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eScrew-held insert retention for secure seating and repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CDHH-style boring toolholders that accept a 5\/32 inch inscribed circle insert with screw-clamp retention.

Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for the screw-clamp fastener per the toolholder manufacturer specification. Inspect the insert pocket for debris or wear before seating a new insert, and confirm insert hand matches the toolholder hand before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CDHH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Diamond (80-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 inch (0.1560 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0070 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0400 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\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 length x 1.5 inches width x 0.25 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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\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: H59873075\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746263105842,"sku":"H59873075","price":271.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68b56df280c722f8e14381934970f73e.jpg?v=1788867831","url":"https:\/\/voomisupply.com\/products\/hertel-h59873075-boring-insert-cdhh-80-diamond-tin-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
