Manufactured to the CDHH insert style with an 80-degree diamond shape, this insert is built for rigidity and accurate material removal. It carries the HC620B manufacturer grade with a C7 material grade designation, making it well-suited for machining ferrous and non-ferrous materials. The CVD coating sequence of TiN, TiC, TiCN, and TiN layers provides wear resistance and extended tool life in demanding cutting environments. At 0.04 inches thick with a 5\/32-inch inscribed circle and a 1\/64-inch corner radius, this insert is engineered for tight tolerances in finish and semi-finish boring applications.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in precision boring tool holders that accept CDHH-style screw-held inserts. Typical applications include CNC boring operations in production machine shops, tool rooms, and manufacturing environments where consistent diameter control and surface finish are required. The 15-degree relief angle helps reduce cutting forces and minimize rubbing on the bore wall. It is suitable for machining operations requiring a compact insert geometry with a controlled corner radius for fine tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond insert shape for rigid, low-vibration boring cuts\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction with HC620B grade for durability in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eCVD-applied multilayer coating: TiN, TiC, TiCN, TiN for extended wear life\u003c\/li\u003e\n\u003cli\u003e1\/64-inch corner radius for controlled surface finish in finish boring passes\u003c\/li\u003e\n\u003cli\u003e15-degree relief angle reduces cutting friction against bore walls\u003c\/li\u003e\n\u003cli\u003eScrew-held insert retention for positive clamping and accurate indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in boring tool holders that accept CDHH-style screw-clamped inserts with a 5\/32-inch inscribed circle and 0.04-inch insert thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the boring bar and tool holder are fully de-energized and the machine spindle is locked before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified clamping screw to seat the insert securely — do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before installation to ensure accurate seating and runout control.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CDHH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1.20.61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: 80-Degree Diamond\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: C7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC620B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN, TiC, TiCN, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/32 inches (0.1560 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\u003eThickness\u003c\/strong\u003e: 0.04 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\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: H59872937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733252047154,"sku":"H59872937","price":292.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fc0e0eb285b57a557caae5e2b982eef.jpg?v=1788753302","url":"https:\/\/voomisupply.com\/products\/hertel-h59872937-boring-insert-80-diamond-solid-carbide-hc620b","provider":"Voomi Supply","version":"1.0","type":"link"}
