Built from high-speed steel with a bright uncoated finish, it features an 82-degree included angle and a 7\/8-inch head diameter. The straight-cylindrical shank measures 1\/2 inch in diameter for secure chuck engagement. Weighing 0.5 pounds, this tool is suited for machinists, tool-and-die techs, and maintenance professionals who need consistent countersink geometry for fastener seating and hole preparation.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in general metalworking, maintenance repair, and light manufacturing environments where 82-degree flat-head fastener prep is required. The 3-flute design provides a balance of cutting speed and surface finish quality in ferrous and non-ferrous materials. It fits standard drill presses, milling machines, and hand drill setups with a 1\/2-inch chuck or collet. No pilot is included, making it appropriate for use with a drill press vise or center-guided fixture to maintain hole alignment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree included angle (41-degree centerline angle) for standard flat-head fastener countersinking\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances material removal rate with finish quality\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup risk in tight-tolerance applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with no pilot for flexible use across hole sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-geometry countersink for use in drill presses, milling machines, and hand drills equipped with a 1\/2-inch chuck or collet, suitable for countersinking 82-degree flat-head fastener holes in metal, wood, and composite materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachinists and maintenance technicians should secure the workpiece firmly before operation to prevent walkout, as this tool does not include a pilot. Use appropriate cutting fluid or lubricant when working ferrous metals to extend tool life and improve finish. Always verify spindle speed is set to a rate appropriate for the workpiece material and head diameter before engaging the cut. Inspect the shank seating in the chuck or collet before each use to confirm concentricity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 7\/8 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: 3\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: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC4082056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697053008178,"sku":"SC4082056","price":57.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aabf1b22150056bb1b485da036ac4c50.jpg?v=1788348853","url":"https:\/\/voomisupply.com\/products\/value-collection-sc4082056-countersink-82-degree-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
