Built with an 82-degree included angle, it conforms to standard flat-head fastener geometry used across most production and maintenance environments. The 1-1\/4 inch head diameter provides consistent material removal, while the 3\/4 inch straight-cylindrical shank seats securely in standard drill chucks and collet holders. The bright, uncoated finish suits a wide range of ferrous and non-ferrous workpieces. This tool is installed and operated by machinists, tool-and-die workers, and maintenance technicians working with drill presses, CNC machining centers, or hand-held power tools.\u003c\/p\u003e\n\u003cp\u003eThe SC1082116 countersink is suited for right-hand cutting in single-pass countersinking operations on flat or low-profile surfaces. The single-flute design reduces chatter and produces a cleaner seat compared to multi-flute options in interrupted or hand-fed applications. It does not include a pilot, making it compatible with pre-drilled pilot holes sized to the fastener specification. Typical use cases include countersinking for flat-head machine screws, sheet metal assemblies, and structural fabrication work requiring flush fastener seating. This tool does not function as a drill and is intended for countersinking only.\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 reduces chatter and improves surface finish in hand-fed operations\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch straight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch head diameter for consistent countersink seat formation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no pilot included, requires pre-drilled hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard supply countersink for use in drill presses, CNC machining centers, and hand-held power tools accepting a 3\/4 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and power is off before inserting or removing the tool from the chuck or collet. Secure the 3\/4 inch shank fully within the chuck jaws or collet to the recommended engagement depth for the toolholder being used. Always pre-drill a pilot hole to the appropriate fastener diameter before countersinking — do not use this tool as a drill. Operate at speeds appropriate for the workpiece material and tool diameter per standard machining reference tables.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eHead Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/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\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\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\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 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: SC1082116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703164371250,"sku":"SC1082116","price":77.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10cd678ef05614ec0784039904206236.jpg?v=1788415168","url":"https:\/\/voomisupply.com\/products\/value-collection-sc1082116-countersink-82-deg-1-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
