With a 5\/8-inch head diameter and a 100-degree included angle, it produces consistent conical seats for flat-head fasteners and deburring operations. The straight-cylindrical shank measures 5\/8 inch in diameter, making it compatible with standard drill chucks and collet holders. Four flutes provide balanced cutting action and efficient chip evacuation. This tool is installed and operated by machinists, tool-and-die workers, and maintenance technicians working on precision fabrication and assembly tasks.\u003c\/p\u003e\n\u003cp\u003eThe 334-307080 countersink suits bench-drill, drill-press, and CNC machining center applications where controlled countersinking depth and surface finish are required. The 100-degree included angle is a common specification for aerospace and general metalworking fastener seat preparation. The carbide construction supports use in harder workpiece materials where high-speed steel tooling would wear prematurely. Single-piece packaging makes it straightforward to add to a tool crib or individual toolbox without sorting through multi-unit quantities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-inch head diameter for standard countersink profiles\u003c\/li\u003e\n  \u003cli\u003e100-degree included angle suits flat-head fastener seating and chamfering\u003c\/li\u003e\n  \u003cli\u003eFour flutes for balanced cutting and efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch straight-cylindrical shank fits standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cutting tool replacement for drill press, manual, and CNC machining setups requiring a 5\/8-inch straight-shank countersink with a 100-degree included angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified maintenance technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and confirm runout is within acceptable limits for the application. Always power down and de-energize the machine spindle before changing or adjusting tooling. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 334-307080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728727933234,"sku":"334-307080","price":300.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3fcea4e8bb30a69d9b9e6ab33132146.jpg?v=1788695538","url":"https:\/\/voomisupply.com\/products\/hertel-334-307080-carbide-countersink-5-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
