Built from high-speed steel (HSS) with a bright, uncoated finish, it features a 90-degree included angle and six flutes for clean, chatter-resistant cutting in right-hand rotation. The 1-inch straight-cylindrical shank seats securely in standard drill press or milling machine chucks. At 1.99 pounds, this is a full-size countersink suited for production environments where consistent, repeatable countersink geometry is required on larger fastener seats.\u003c\/p\u003e\u003cp\u003eThis countersink is used in metal fabrication shops, machine shops, and maintenance facilities for preparing countersunk holes to accept flat-head fasteners or for deburring drilled holes in ferrous and non-ferrous metals. The 2-inch head diameter and 90-degree included angle match the geometry of standard flat-head machine screws and aerospace-style fasteners. It is installed by machinists, tool-and-die professionals, and maintenance technicians operating drill presses, milling machines, or hand-held power tools with appropriate chuck capacity for the 1-inch shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree included angle matches standard flat-head fastener geometry\u003c\/li\u003e\n\u003cli\u003eSix flutes deliver smooth, chatter-resistant cutting action\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles a wide range of metals\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for general-purpose metalworking use\u003c\/li\u003e\n\u003cli\u003e1-inch straight-cylindrical shank fits standard large-bore chucks\u003c\/li\u003e\n\u003cli\u003eSingle-end design with no pilot for flexible hole alignment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose countersink for use in drill presses, milling machines, and high-torque hand-held power tools capable of accepting a 1-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or fabrication technicians using a drill press or milling machine with a chuck rated for a 1-inch shank diameter. Ensure the spindle and workpiece are fully secured before operation and set spindle speed appropriate to the workpiece material and tool diameter. Never exceed the recommended RPM range for the tool diameter or material being cut. Eye protection and appropriate guarding are required per standard shop safety practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.99 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC2090200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692128338226,"sku":"SC2090200","price":180.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da5fbfa46003e8aba0037a86e9200db4.jpg?v=1788293465","url":"https:\/\/voomisupply.com\/products\/value-collection-sc2090200-countersink-90-degree-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
