Built from high-speed steel with a bright uncoated finish, this tool delivers consistent performance on ferrous and non-ferrous materials. It features a 90-degree included angle (45-degree centerline angle) and a straight-cylindrical 1\/2-inch shank for secure chuck mounting. The fluteless design produces a smooth, chatter-free surface finish and is particularly well suited for deburring drilled holes. Machinists and tool and die technicians are the primary installers of this type of cutting tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in manual drill press, CNC, and hand-held applications where a clean 90-degree countersunk seat is required. The minimum cutting diameter is 9\/16 inch and the maximum cutting diameter is 1-1\/16 inches, making it appropriate for a wide range of fastener head profiles in light to medium stock. The single-end construction keeps the tool compact for use in tight setups. It ships individually and is suited for both production and maintenance shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree included angle with 45-degree centerline angle for standard countersunk fastener seats\u003c\/li\u003e\n  \u003cli\u003eFluteless design minimizes chatter and produces a smooth hole finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 1\/2-inch shank fits standard drill chucks and tool holders\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose countersinking and deburring\u003c\/li\u003e\n  \u003cli\u003eSingle-end, no-pilot design for flexible positioning in a range of hole sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink compatible with standard drill presses, lathes, milling machines, and handheld drills accepting a 1\/2-inch straight-cylindrical shank, for use in countersinking and deburring applications across a range of materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and fabricators using a standard drill chuck or collet rated for the 1\/2-inch shank diameter. Ensure the workpiece is securely fixtured before engaging the cutter, and confirm the spindle speed is appropriate for the material being machined. No pilot is included, so center alignment relies on the operator or existing pilot hole. Inspect the cutting edge for wear before each use and replace if chipping or dullness is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 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\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, 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: 0.27 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: SC5090D4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708630630706,"sku":"SC5090D4","price":63.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1ff5855b2c806d9fdd2688da1e9ff0a.jpg?v=1788447532","url":"https:\/\/voomisupply.com\/products\/value-collection-sc5090d4-countersink-90-deg-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
