Each tool combines the drilling and countersinking operations into a single pass, reducing tool changes and setup time on the shop floor or jobsite. The set features a 60-degree included angle with a plain cutting edge, a geometry suited for producing clean countersunk holes in steel, cast iron, and other ferrous materials. The cobalt construction provides added heat resistance compared to standard high-speed steel, making these tools a practical choice for production drilling in harder workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis set is intended for use by machinists, fabricators, and trade professionals who need to drill and countersink pilot holes for flathead screws and similar fasteners in a single operation. The five-piece range covers trade sizes 1 through 5, giving the user a graduated selection for different fastener sizes. Typical applications include sheet metal fabrication, light structural work, and general machine shop countersinking tasks where cobalt tooling is preferred over standard HSS.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-piece set covering trade sizes 1 through 5\u003c\/li\u003e\n  \u003cli\u003eCobalt construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for standard flathead fastener countersinking\u003c\/li\u003e\n  \u003cli\u003ePlain cutting edge geometry for clean, consistent results in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCombination drill and countersink design completes both operations in one step\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose combination drill and countersink set compatible with standard drill presses, CNC machining centers, and hand-held power drills accepting straight-shank tooling in trade sizes 1 through 5.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or trained trade professional. Secure the workpiece firmly before drilling and ensure the tool is properly seated and tightened in the chuck or collet before operation. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary cutting tools. Do not exceed the recommended speed range for the tool diameter and workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Trade Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Trade Size\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEdge Type\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\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: KEO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 90000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":51993654100274,"sku":"90000","price":121.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a562cd86731ff9ba1dc2db576a6d6769.jpg?v=1789991276","url":"https:\/\/voomisupply.com\/products\/keo-90000-cobalt-combo-drill-countersink-set-5-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
