It features a 120-degree included angle and a 3\/4-inch head diameter, making it suited for countersinking fastener seats in structural and machined components. The straight-cylindrical shank measures 3\/4 inch in diameter for secure chuck or collet retention. With 4 flutes, it provides balanced cutting action and consistent chip evacuation during operation. This tool is intended for use by machinists, toolmakers, and metalworking tradespeople working on CNC or manual machines.\u003c\/p\u003e\n\u003cp\u003eThe 334-208100 is applicable in general metalworking environments where countersunk fastener holes are required in ferrous and non-ferrous materials. Its carbide construction supports use in harder materials and higher-speed applications where high-speed steel tools would wear prematurely. Typical installations include production machining, maintenance shops, and fabrication environments requiring precise, repeatable countersink geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-degree included angle for standard countersunk fastener seat preparation\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch head diameter provides adequate cutting coverage for common fastener sizes\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4-flute design promotes smooth cutting action and efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with standard drill chucks and collet holders\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 metalworking machines equipped with standard straight-shank toolholders accepting a 3\/4-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis countersink is installed by machinists in drill presses, milling machines, or CNC machining centers with appropriate straight-shank toolholding. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank seating and chuck or collet tightness before initiating a cut. Use appropriate cutting speeds and feeds for the workpiece material to avoid tool damage or premature wear.\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\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 120 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 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: 334-208100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744529219890,"sku":"334-208100","price":384.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dfd423fcada145791cd0d28aba877b1.jpg?v=1788857590","url":"https:\/\/voomisupply.com\/products\/hertel-334-208100-carbide-countersink-4-flute-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
