With an 82-degree included angle and a 5\/16-inch head diameter, it produces clean, consistent countersunk seats suited to flat-head fastener installations. The 1\/4-inch straight cylindrical shank fits standard drill chucks and quick-change holders. The bright, uncoated finish is appropriate for general-purpose use on ferrous and non-ferrous materials. This tool is typically installed by machinists, maintenance technicians, and experienced tradespeople who require accurate countersinking without a pilot guide.\u003c\/p\u003e\n\u003cp\u003eThe SC1082020 is suited for countersinking in hand-drill, drill press, and light CNC setups where a single-flute geometry is preferred for reduced chatter and cleaner entry. The 82-degree angle matches the standard for flat-head machine screws and sheet metal fasteners common in HVAC panel work, electrical enclosure assembly, and general mechanical fabrication. No pilot is included, so the operator controls concentricity through fixture or layout.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head fastener geometry\u003c\/li\u003e\n  \u003cli\u003eSingle flute design reduces chatter and improves surface finish in the countersink seat\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight cylindrical shank fits standard drill chucks and quick-change systems\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for general-purpose countersinking without specialty coating requirements\u003c\/li\u003e\n  \u003cli\u003eNo pilot included — full operator control over hole concentricity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink compatible with standard 1\/4-inch straight-shank drill chucks, collet holders, and quick-change tool systems used in hand drills, drill presses, and light CNC equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the 1\/4-inch shank firmly in the chuck before operation and verify the spindle is at a safe, low speed appropriate for the workpiece material. Power down the drill or press completely before changing or inspecting the tool. Because no pilot is included, use a center-punched layout or fixture to maintain concentricity. Inspect the cutting edge before each use and replace the tool if chipping or dulling is observed to avoid poor seat quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/16 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: 1\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\/4 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\u003ePilot Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\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: 0.09 pounds\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: SC1082020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697994170674,"sku":"SC1082020","price":17.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84ac4afff2df5b53c153279c8696f14d.jpg?v=1788356596","url":"https:\/\/voomisupply.com\/products\/value-collection-sc1082020-countersink-82-deg-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
