Built from high-speed steel (HSS) with a bright, uncoated finish, it runs a 90-degree included angle and a 45-degree centerline angle. The 1\/4-inch straight-cylindrical shank fits standard drill chucks and quick-change holders. With no flutes and a right-hand cutting direction, this tool produces clean, burr-free chamfers in a single pass. It weighs approximately 0.6 pounds. Machinists, toolroom technicians, and maintenance tradespeople reach for this style of countersink when prepping drilled holes for flat-head fasteners or cleaning up sharp edges on sheet metal and plate.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for bench drilling, drill-press work, and hand-drill applications where a 90-degree chamfer is required. The cutting range spans from a minimum cutting diameter of 5\/32 inch to a maximum cutting diameter of 13\/32 inch, making it practical for a broad range of fastener hole sizes found in light fabrication, maintenance repair, and general machine shop use. It does not include a pilot, so it is best used in pre-drilled or center-punched holes to maintain concentricity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree included angle for standard flat-head fastener countersinks\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose shop use\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight-cylindrical shank fits standard drill chucks and quick-change holders\u003c\/li\u003e\n  \u003cli\u003eCutting range from 5\/32 inch to 13\/32 inch to accommodate multiple fastener sizes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, single-end design with no pilot\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in drill presses, CNC machines, and hand drills equipped with a 1\/4-inch or larger chuck.

Use low spindle speeds and consistent feed pressure to avoid chatter and maintain hole concentricity, especially without a pilot. Power down and secure the workpiece before tool changes. Eye protection is required whenever operating rotary cutting tools.\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: 5\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 13\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\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\u003eFinish\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\u003ePilot Included\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\u003eWeight\u003c\/strong\u003e: 0.6 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: SC5090D1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715769270578,"sku":"SC5090D1","price":26.29,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cff43e77f2b3d1c2dddd841457fe667.jpg?v=1788518129","url":"https:\/\/voomisupply.com\/products\/value-collection-sc5090d1-countersink-90-deg-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
