Built from high-speed steel (HSS), this tool delivers consistent cutting performance across a range of production and maintenance applications. The 2-inch head diameter and 82-degree included angle (41-degree centerline angle) make it well suited for standard flat-head fastener seat preparation. The straight-cylindrical shank measures 3\/4 inch in diameter and 1-1\/4 inches in length, providing secure chuck retention. With 6 flutes and a right-hand cutting direction, it produces a smooth, chatter-reduced finish on the countersunk surface.\u003c\/p\u003e\u003cp\u003eThis countersink is intended for use in machine shop, manufacturing, and maintenance environments where precise fastener seating is required. It is typically run in a drill press, milling machine, or lathe setup. The 82-degree angle matches the standard specification for flat-head machine screws and similar fasteners, making it a practical choice for metalworking, fabrication, and repair operations where a clean, accurate countersink profile is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch head diameter for large-diameter countersink applications\u003c\/li\u003e\n\u003cli\u003e82-degree included angle sized for standard flat-head fastener seating\u003c\/li\u003e\n\u003cli\u003e6 flutes for reduced chatter and improved surface finish\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across common metalworking materials\u003c\/li\u003e\n\u003cli\u003e3\/4-inch straight-cylindrical shank for standard chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for use with conventional machine rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use countersink for metalworking operations requiring an 82-degree, 2-inch head diameter tool with a 3\/4-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists and toolmakers into a drill press, mill, or lathe using a chuck or collet sized for a 3\/4-inch shank. Ensure the machine is fully stopped and de-energized before mounting or removing the tool. Use appropriate speeds and feeds for the workpiece material to avoid overheating the HSS cutting edges. Do not use in hand-held drills where lateral loading may damage the shank or compromise hole accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 41 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 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: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.27 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: KEO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 919-000-364\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":51972011327794,"sku":"919-000-364","price":205.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6fd1d4c210dc2e9995a52e159831e17f.jpg?v=1789960906","url":"https:\/\/voomisupply.com\/products\/keo-919-000-364-countersink-2-in-82-degree-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
