It features a 3\/16 inch head diameter and a 100-degree included angle, making it well suited for flat-head fastener seat preparation where a wide-angle chamfer is required. The 4-flute design promotes smooth cutting action and improved chip evacuation compared to single-flute styles. The straight-cylindrical shank allows secure clamping in standard drill chucks or collet holders. Machinists, tool-and-die technicians, and precision fabricators are the typical users of this style of countersink.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in machine shop, production floor, and maintenance-repair-overhaul (MRO) settings where accurate fastener-seat geometry is critical. The 100-degree included angle is commonly specified for aerospace and general-purpose countersink applications where a wider seat angle is called out in the print. The compact 3\/16 inch head diameter makes it suitable for work in tight areas or on smaller workpieces where a larger-diameter tool would not fit. It is sold and packaged as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch head diameter suited for small-diameter fastener seat preparation\u003c\/li\u003e\n  \u003cli\u003e100-degree included angle for wide-seat chamfer geometry\u003c\/li\u003e\n  \u003cli\u003e4-flute design promotes smooth cutting and efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with 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 replacement or direct-use countersink for standard drill press, CNC machining center, and hand-drill setups accepting a straight-cylindrical shank tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis countersink is installed by machinists or tool-setup technicians in conventional or CNC machine spindles. Ensure the machine is fully powered down and the spindle is locked before inserting or removing the tool. Secure the straight shank firmly in the collet or chuck to the manufacturer-specified clamping depth to prevent slippage during operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain 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: 3\/16 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: 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\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: 334-302080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735264166194,"sku":"334-302080","price":52.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/208d7205684a46898ff12976c40576d1.jpg?v=1788771185","url":"https:\/\/voomisupply.com\/products\/hertel-334-302080-carbide-countersink-3-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
