It features a 100-degree included angle and a 7\/8-inch head diameter, making it suitable for creating clean, accurately angled seat profiles in metal and other materials. The straight-cylindrical shank measures 1\/2 inch in diameter for secure chuck engagement. The bright, uncoated finish is standard for general-purpose HSS tooling. This countersink is used by machinists, tool-and-die professionals, and maintenance technicians working with drill presses, milling machines, or hand-held power tools.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for countersinking operations in ferrous and non-ferrous metals, plastics, and composite materials in production, maintenance, and repair environments. The single-flute geometry is well-suited for applications where chatter reduction and surface finish quality are priorities. It fits standard 1\/2-inch chucks and collets commonly found in shop and field tooling setups. This part is sold individually and intended for benchtop or machine-mounted use by skilled trade personnel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100-degree included angle with a 50-degree centerline angle for standard fastener seat profiles\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design reduces chatter and improves surface finish in softer and medium-hardness materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight-cylindrical shank fits standard chucks and collets without adapters\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch head diameter accommodates common fastener countersink requirements\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose use without specialized coatings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in standard 1\/2-inch drill chucks and collet holders on drill presses, lathes, and milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or experienced trade professionals familiar with rotary cutting tools. Secure the workpiece firmly before beginning the countersinking operation to prevent movement. Always operate at appropriate spindle speeds for the workpiece material and tool diameter. Inspect the cutting edge for wear or damage before each use and replace the tool if chipping or dullness is observed.\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: 100 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 50 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\/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\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: 0.25 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: SC10100056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695766864178,"sku":"SC10100056","price":46.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/901b818c0ce784950fc62ff536a96a6e.jpg?v=1788338113","url":"https:\/\/voomisupply.com\/products\/value-collection-sc10100056-countersink-100-deg-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
