Built from high-speed steel with a bright uncoated finish, this tool cuts at an 82-degree included angle, which is the standard for most inch-series flat-head fastener applications. The 0-flute design functions as a cone-style burnishing countersink, producing a smooth seat without chip buildup. The 1\/2-inch straight cylindrical shank fits standard drill chucks and countersink holders. Machinists, tool-and-die workers, and sheet metal fabricators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis countersink covers a minimum cutting diameter of 9\/16 inches and a maximum cutting diameter of 1-1\/16 inches, making it suitable for preparing seats for common flat-head machine screws and similar fasteners in that size range. It is appropriate for use in manual drill presses, CNC machines, and hand-held drill applications where a clean, consistent countersink seat is required. The 82-degree geometry is a match for standard unified inch flat-head screw specifications. No pilot is included, so a center-drilled hole or existing through-hole is required before use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree included angle matches standard inch flat-head fastener seat geometry\u003c\/li\u003e\n\u003cli\u003e0-flute cone design produces a smooth, chatter-reduced countersink seat\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles a wide range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for general-purpose machining applications\u003c\/li\u003e\n\u003cli\u003e1\/2-inch straight cylindrical shank for compatibility with standard drill chucks and holders\u003c\/li\u003e\n\u003cli\u003eSingle-end design; no pilot included — requires a pre-drilled hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose countersink for use in standard drill press, CNC, and hand-drill setups where an 82-degree flat-head screw seat is required with a cutting range of 9\/16 to 1-1\/16 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or experienced fabricator should set spindle speed appropriate to the workpiece material before use — consult published HSS cutting speed tables for the specific material. Always secure the workpiece and ensure the drill chuck is tightened to rated torque before operation. Power down and de-energize the machine before changing or adjusting the countersink. Do not use this tool on hardened steel without confirming material compatibility with the HSS grade.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Cutting Diameter\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 1-1\/16 inches\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\u003eFinish\/Coating\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; Deburring\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: 0.31 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SC5082D4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692092227890,"sku":"SC5082D4","price":54.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b46a737b39cfb340683d85a81ac3a328.jpg?v=1788292985","url":"https:\/\/voomisupply.com\/products\/value-collection-sc5082d4-countersink-82-deg-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
