It features a 5\/8-inch head diameter and a 100-degree included angle, making it well suited for applications that require a wider chamfer profile than the standard 82-degree or 90-degree tools. The straight cylindrical shank measures 5\/8 inch in diameter for positive chuck retention. Carbide construction provides edge durability and heat resistance during high-speed cutting operations. Machinists and tool-and-die technicians are the primary installers of this type of tooling.\u003c\/p\u003e\u003cp\u003eThis countersink is used in ferrous and non-ferrous metal cutting applications where a 100-degree chamfer angle is specified. The single-flute geometry reduces chatter and promotes a clean, consistent finish in materials such as aluminum, steel, and brass. It is appropriate for use in CNC machining centers, drill presses, and manual milling operations where controlled countersinking depth is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100-degree included angle for wide chamfer profiles\u003c\/li\u003e\n\u003cli\u003eSingle-flute design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCarbide construction for extended tool life and heat resistance\u003c\/li\u003e\n\u003cli\u003e5\/8-inch head diameter for medium-range hole chamfering\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for secure chuck or collet holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit countersink for machine setups requiring a 5\/8-inch, 100-degree single-flute carbide tool with a straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or qualified tooling technicians. Secure the straight cylindrical shank firmly in a compatible chuck or collet before operation. Ensure the spindle is fully stopped before tooling changes, and verify that cutting speed and feed rate are appropriate for the workpiece material. Follow applicable shop safety standards and machine manufacturer guidelines during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/8 inches\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: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\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\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: 331-207080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":52126262526258,"sku":"331-207080","price":232.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94f7564ea22bc13ca1835aef0095e8e3_cab2ecea-4018-4cc2-9a5d-c8a568456185.jpg?v=1790088217","url":"https:\/\/voomisupply.com\/products\/hertel-331-207080-countersink-5-8-in-100-degree-1-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
