It features a 3\/16 inch head diameter with a 60-degree included angle and six flutes, delivering clean, smooth countersunk seats in a single pass. The straight cylindrical shank measures 3\/16 inch in diameter, making it compatible with standard collet chucks and drill chucks on milling machines, drill presses, and CNC equipment. Machinists and tool-and-die professionals rely on this geometry for consistent, chatter-free performance across a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis countersink is suited for light-duty countersinking tasks where a small-diameter, fine-finish tool is required. Typical applications include chamfering fastener seats in thin stock, deburring precision bores, and spotting screw clearance holes. The 60-degree angle is standard for many flat-head screw and rivet seat preparations in aerospace, electronics, and general manufacturing environments. The carbide construction supports use in harder workpiece materials where high-speed steel tooling would dull prematurely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16 inch head diameter for precise, small-bore countersinking\u003c\/li\u003e\n\u003cli\u003e60-degree included angle matches standard flat-head fastener seat geometry\u003c\/li\u003e\n\u003cli\u003eSix flutes provide smooth cutting action and improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collet and drill chuck setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-geometry countersink for use in milling machines, drill presses, and CNC machining centers equipped with collet chucks or drill chucks accepting a 3\/16 inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or toolroom personnel. Secure the shank fully in the collet or chuck before starting the spindle, and verify runout before cutting. Always power down and lock out the machine before changing tooling. Use appropriate cutting speeds and feeds for the workpiece material and carbide tooling to avoid chipping the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 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\u003eWeight\u003c\/strong\u003e: 0.15 pounds\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: 336-202050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755730305330,"sku":"336-202050","price":31.89,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/059932bb8d8d73863757a67488877bcb.jpg?v=1788958746","url":"https:\/\/voomisupply.com\/products\/hertel-336-202050-carbide-countersink-3-16-in-60-degree-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
