It features a 3\/4 inch head diameter and a 100-degree included angle, making it suited for fastener seating that requires a wider countersink profile than the more common 82- or 90-degree tools. The 1\/2 inch straight cylindrical shank provides secure, repeatable clamping in standard drill chucks or collet holders. With 4 flutes, this countersink delivers improved chip evacuation and a smoother surface finish compared to single- or double-flute designs. It is intended for use by machinists, tool-and-die technicians, and precision fabricators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for chamfering, deburring, and fastener-hole preparation in metals including steel, aluminum, and cast iron. The carbide construction supports higher cutting speeds and extended tool life compared to high-speed steel alternatives, making it appropriate for production runs and automated machining centers as well as manual drill press work. It is sold individually and is intended for shops and technicians requiring consistent, repeatable countersink geometry on close-tolerance assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch head diameter for wide countersink coverage on larger fastener heads\u003c\/li\u003e\n  \u003cli\u003e100-degree included angle for non-standard fastener seating requirements\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry improves chip flow and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction extends tool life and supports elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch straight cylindrical shank fits standard chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use carbide countersink for standard 1\/2 inch straight-shank toolholders, drill chucks, and collet systems used in machining and fabrication applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with proper speeds and feeds for carbide cutting tools. Secure the shank fully within the chuck or collet before operation and verify runout before engaging the workpiece. Carbide is brittle — avoid lateral loading, interrupted cuts, or impact conditions that could cause chipping or tool breakage. Refer to the machine manufacturer guidelines and applicable shop safety procedures when setting up countersink operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/4 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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 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\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: 334-008080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729676468530,"sku":"334-008080","price":139.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ba162358518bb0a3201906336d4dd51.jpg?v=1788707630","url":"https:\/\/voomisupply.com\/products\/hertel-334-008080-carbide-countersink-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
