Built from high-speed steel with a bright, uncoated finish, this tool features a 90-degree included angle and a 45-degree centerline angle. The straight-cylindrical shank measures 0.25 inches in diameter for secure chuck engagement. The cutting range spans from 0.0625 inches minimum to 0.234 inches maximum, making it suited for small-hole chamfering tasks. It is a head-only design with no pilot and a double end type. Machinists and maintenance technicians are the typical installers of this tool.\u003c\/p\u003e\u003cp\u003eThis countersink is used in machining, fabrication, and maintenance applications where chamfering or deburring of small-diameter holes is required. The 90-degree included angle is the most common standard for countersunk fastener seats, making this tool directly applicable to preparing holes for flat-head screws and similar hardware. Its compact cutting range suits thin-stock and precision work where larger tools would be inappropriate. Right-hand cutting direction aligns with standard drill press and CNC spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree included angle for standard countersunk fastener seat preparation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for general-purpose metal cutting\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for dry or lubricated cutting\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 0.25-inch shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eDouble-end design extends usable tool life\u003c\/li\u003e\n\u003cli\u003eNo pilot required, allowing flexible hole alignment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose countersink for use in standard drill presses, hand drills, and CNC lathes or mills accepting a 0.25-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a drill press, hand drill, or CNC machine. Secure the shank fully in the chuck or collet before operation and confirm the spindle is fully stopped before changing or adjusting the tool. Use appropriate cutting fluid for harder materials to reduce heat buildup and extend tool life. Always wear appropriate eye protection when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 45 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: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 0.234 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountersink Head Only\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: SC5090D0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709535879474,"sku":"SC5090D0","price":22.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e6436fc62888741830a720fba97b94d.jpg?v=1788457659","url":"https:\/\/voomisupply.com\/products\/value-collection-sc5090d0-countersink-90-degree-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
