Built from high-speed steel with a bright, uncoated finish, it delivers consistent performance in ferrous and non-ferrous metals, wood, and plastics. The tool measures 3.25 inches in overall length with a body diameter of 0.625 inches, a drill point diameter of 0.25 inches, and a drill point length of 0.25 inches. The 118-degree drill point angle and 90-degree included angle are standard geometry for general-purpose countersinking. Right-hand cutting direction suits conventional drilling setups without modification.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is suited for production and maintenance work where countersinking for flat-head fasteners is required. Trade size 7 makes it appropriate for screw clearance and countersink preparation on light structural assemblies, sheet metal, and fabricated components. It is used in machine shops, HVAC fabrication, electrical panel work, and general metalworking applications. The plain cutting edge style and non-tapered, non-insertable design keep setup simple and repeatable on drill presses and handheld drilling equipment alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-pass operation drills pilot hole and countersink simultaneously\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of materials\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for general-purpose drilling geometry\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle for standard flat-head fastener seating\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, plain cutting edge  -  compatible with standard drill presses and portable drills\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for easy inspection of cutting edge condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use combo drill countersink for applications requiring trade size 7 with a 5\/8-inch body diameter and 90-degree countersink geometry in standard drill chucks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists, fabricators, and trade professionals using standard drill press or handheld drilling equipment. Secure the workpiece before drilling and use appropriate cutting fluid when working with harder metals to extend tool life. Inspect the cutting edges before use and replace the tool if chipping or wear is visible. Follow applicable shop safety standards and ensure the drill chuck is properly tightened before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241603\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: 906-000-163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":51972187324722,"sku":"906-000-163","price":51.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11d119e8cdc885bbe6b9a9fdcd8b1554.jpg?v=1789963965","url":"https:\/\/voomisupply.com\/products\/keo-906-000-163-combo-drill-countersink-size-7-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
