Built from high-speed steel with a bright uncoated finish, it features a 90-degree included angle and a 45-degree centerline angle. The tool accepts a 1\/4-inch straight shank and cuts a range from 3\/16 inch minimum to 17\/32 inch maximum diameter. With zero flutes and right-hand cutting direction, it delivers a clean, consistent chamfer without the chatter sometimes associated with multi-flute designs. Machinists and tool-and-die professionals are the primary users of this style of countersink.\u003c\/p\u003e\n\u003cp\u003eThis countersink suits general machining and fabrication environments where standard 90-degree chamfers are required for fastener seating, edge deburring, or hole preparation. It is a single-end tool with no pilot included, making it compatible with standard drill presses, milling machines, and hand-held power tools equipped with a 1\/4-inch collet or chuck. Its compact cutting range makes it well suited to light- to medium-duty applications in production and maintenance shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree included angle for standard fastener chamfering and countersinking\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eZero-flute design reduces chatter and produces a smooth chamfer surface\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with conventional drill and mill setups\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight-cylindrical shank fits standard collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose countersinking applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for machines and setups accepting a 1\/4-inch straight-cylindrical shank countersink with a 90-degree included angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling professional. Secure the 1\/4-inch shank firmly in the collet or drill chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Power down the machine and confirm zero rotation before changing or inspecting the tool. Do not exceed the recommended spindle speed for the workpiece material and tool diameter.\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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 17\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/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\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking, Deburring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SC5090D2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695066677554,"sku":"SC5090D2","price":28.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd6681e9dae0eb20aef36830760062fc.jpg?v=1788331009","url":"https:\/\/voomisupply.com\/products\/value-collection-sc5090d2-countersink-90-degree-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
