Each tool combines a twist drill point with a 60-degree included-angle countersink in a single body, eliminating the need to swap tools when drilling and countersinking in one operation. The plain-edge cutting geometry suits a wide range of materials encountered in production and maintenance work. Machinists, tool-and-die tradespeople, and maintenance technicians keep sets like this on hand for repetitive fastener prep work on metal, wood, and composite materials.\u003c\/p\u003e\n\u003cp\u003eThis set is suited for use in machine shops, fabrication environments, and maintenance facilities where countersunk fastener holes are a routine requirement. The graduated size range from trade size 1 through 8 gives the technician coverage across the most common countersunk screw and fastener diameters. The 60-degree included angle matches standard flat-head machine screw seat geometry widely used in metalworking applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-piece set covering trade sizes 1 through 8 in a single package\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for hardness and wear resistance across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle matches standard flat-head fastener seat geometry\u003c\/li\u003e\n  \u003cli\u003ePlain-edge cutting profile for general-purpose countersinking\u003c\/li\u003e\n  \u003cli\u003eCombo drill and countersink design performs both operations without a tool change\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose combo drill and countersink set compatible with standard drill press chucks, CNC machining center toolholders, and hand-held drill drivers that accept straight-shank tooling across the trade size 1 to 8 range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of combo drill countersinks is performed by machinists or maintenance technicians operating drill presses, lathes, or hand-held power drills. Secure the workpiece firmly before beginning to prevent tool deflection and ensure accurate seat geometry. Run speeds appropriate to the workpiece material and tool diameter; consult a standard machining speeds-and-feeds reference when working with harder materials. Inspect each tool for chipping or wear before use and replace any damaged tools in the set.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEdge Style\u003c\/strong\u003e: Plain Edge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\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: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePieces in Set\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 01031582\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":52025628164402,"sku":"01031582","price":158.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbdc48520a44e84b7ed38cdabcf9221b.jpg?v=1790015712","url":"https:\/\/voomisupply.com\/products\/keo-01031582-hss-combo-drill-countersink-set-8-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
