Built from high-speed steel (HSS) with a bright uncoated finish, it features a 90-degree included angle and a 45-degree centerline angle, producing clean, accurate countersunk seats for flat-head fasteners. The 1\/2-inch head diameter pairs with a 1\/4-inch straight-cylindrical shank, making it compatible with standard drill chucks and quick-change holders. At 0.06 pounds, it is a lightweight tool suited for both bench drill press and handheld drill use. No pilot is included. Machinists, toolmakers, and general fabricators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used wherever a 90-degree countersink is required to seat flat-head machine screws, wood screws, or sheet metal fasteners flush with or below a workpiece surface. Typical applications include light fabrication, sheet metal work, woodworking, and general machine shop operations. The 6-flute geometry reduces chatter compared to single- or double-flute designs, producing a smoother finish on the countersunk seat. The straight-cylindrical shank fits standard 1\/4-inch collets and drill chucks without adapters. It is intended for single-end use and does not accept a pilot pin.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree included angle for standard flat-head fastener seating\u003c\/li\u003e\n  \u003cli\u003e6-flute design reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to chip or flake during use\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eSingle-end tool with no pilot — used without a guide pin\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in standard drill presses, CNC machining centers, and handheld drills equipped with a 1\/4-inch chuck or collet capable of accepting a straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists, fabricators, and maintenance technicians using standard drill press or hand drill setups. Secure the 1\/4-inch shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Run at appropriate speeds for the workpiece material — higher speeds for softer materials, lower speeds for harder metals. Inspect the cutting edges for wear before each use; a dull countersink will produce rough seats and may cause workpiece damage.\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: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 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 Length\u003c\/strong\u003e: 1 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\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\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\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: SC2090032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710979539250,"sku":"SC2090032","price":23.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fdbec7d1e4d9112465c90e8f00c690a4.jpg?v=1788473101","url":"https:\/\/voomisupply.com\/products\/value-collection-sc2090032-countersink-90-deg-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
