Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in ferrous and non-ferrous materials. The drill point diameter is 3\/16 inches with a 118-degree point angle, and the included countersink angle is 90 degrees. Overall length is 2.75 inches. This tool is sized at trade size 5 with a 7\/16-inch body diameter and is suited for machine shop, fabrication, and general metalworking applications.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is used in production and job-shop environments where countersunk holes for flat-head fasteners are required. The double-end design allows the tool to be reversed and used from both ends, maximizing tool life before replacement. Right-hand cutting direction makes it compatible with standard drill press and CNC spindle rotation. It is commonly used in sheet metal, light structural fabrication, and general machining work where flush fastener seating is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed steel construction with titanium nitride (TiN) coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for accurate center location and clean entry\u003c\/li\u003e\n\u003cli\u003e90-degree included countersink angle for standard flat-head fastener seating\u003c\/li\u003e\n\u003cli\u003eDouble-end design allows use from both ends, extending tool life\u003c\/li\u003e\n\u003cli\u003ePlain cutting edge style with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eNon-tapered, non-insertable, fixed-geometry tool for consistent results\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard trade size 5 combo drill countersink for use in drill presses, lathes, and CNC machining centers with compatible collets or chucks accepting a 7\/16-inch body diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists, toolmakers, or fabricators using standard drill press or CNC equipment. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Use appropriate speeds and feeds for the material being machined  -  HSS tooling requires lower surface footage than carbide. Secure the workpiece firmly before operation to prevent movement during the drilling and countersinking pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.75 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 (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 906-000-134\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":52024480006450,"sku":"906-000-134","price":35.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b68bf0d24e90c9f4bbfd6ba41793635.jpg?v=1790014828","url":"https:\/\/voomisupply.com\/products\/keo-906-000-134-combo-drill-countersink-size-5-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
