Each countersink features 6 flutes and an 82-degree included angle, making them well-suited for driving flat-head fasteners to flush or below-flush seating depth. Head diameters range from 1\/4 inch to 1 inch, and shank diameters run from 1\/4 inch to 1\/2 inch, giving technicians and machinists a wide range of coverage in a single kit. The bright, uncoated finish allows easy visual inspection of the cutting edges between uses.\u003c\/p\u003e\n\u003cp\u003eThis set is appropriate for use in machine shops, fabrication environments, HVAC sheet metal work, electrical panel installations, and general trade applications where countersinking of flat-head screws or rivets is required. The right-hand cutting direction is standard for conventional drill press and hand-drill use. Straight shanks allow the countersinks to seat directly in standard drill chucks without adapters. The included wood storage block keeps all 8 pieces organized and protects the cutting edges when not in use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-piece set covering head diameters from 1\/4 inch to 1 inch\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction for durability in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003e6-flute design for smooth, consistent cutting action\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle sized for standard flat-head fasteners\u003c\/li\u003e\n  \u003cli\u003eStraight shank, right-hand cut — compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with wood storage block included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink set for use with standard flat-head screws and fasteners requiring an 82-degree seating angle across a range of materials including steel, aluminum, and wood.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a drill press or hand drill using a standard chuck sized for the shank diameter being used. Secure the workpiece before cutting to prevent movement. Use appropriate cutting fluid when countersinking hardened or stainless steel to extend tool life and maintain edge integrity. Inspect flutes for wear or chipping before each use and replace any countersink that shows visible damage to avoid oversized or irregular seat profiles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Head Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Head Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Shank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Shank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\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\u003eStorage Unit Type\u003c\/strong\u003e: Wood Block\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.085 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: SC21828S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690514055474,"sku":"SC21828S","price":307.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd13caf907898e33d8b4c1f7d69d5689.jpg?v=1788270822","url":"https:\/\/voomisupply.com\/products\/value-collection-sc21828s-countersink-set-8-pc-cobalt-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
