It features a 0.002-inch corner radius for fine finishing work and an inscribed circle of 5\/32 inch (0.1563 inch). The insert is 0.04 inches thick and carries a 15-degree relief angle, which provides adequate clearance for interrupted cuts and reduces tool pressure on workpiece materials. Grade HT540B is an uncoated solid carbide formulation classified at material grade C1. Screw-style holding secures the insert firmly in compatible toolholders. This insert is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003cp\u003eThis insert is suited for precision internal boring in metalworking environments, including job shops, production machining cells, and tool rooms. The 80-degree diamond shape suits both turning and boring applications where a sharp, well-defined cutting edge geometry is required. Machinists and CNC operators working with cast iron, non-ferrous metals, and similar materials at lighter depths of cut will find this geometry appropriate. The uncoated carbide substrate is well suited for applications where coating buildup is undesirable, such as aluminum and other non-ferrous alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond (CDHB) insert geometry for precision boring applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate, uncoated, manufacturer grade HT540B, material grade C1\u003c\/li\u003e\n\u003cli\u003e0.002-inch corner radius for fine surface finish requirements\u003c\/li\u003e\n\u003cli\u003e5\/32-inch inscribed circle (0.1563 inch) for compact toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e15-degree relief angle reduces cutting forces and improves clearance\u003c\/li\u003e\n\u003cli\u003eScrew-style insert holding for positive, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application boring insert for CDHB-style screw-clamp toolholders accepting a 5\/32-inch inscribed circle, 0.04-inch-thick diamond inserts with a 15-degree relief angle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the insert screw to the toolholder manufacturer's specification without overtightening, which can fracture the carbide. Inspect the insert seat and clamping screw for debris or wear 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: CDHB\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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT540B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.002 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\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: H59872820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739576140082,"sku":"H59872820","price":281.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38e3c61f43e9c470442858b9f906a4ea.jpg?v=1788816507","url":"https:\/\/voomisupply.com\/products\/hertel-h59872820-boring-insert-cdhb-diamond-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
