Built from high-speed steel with a bright, uncoated finish, this tool features a 0.25-inch body diameter and a 7\/64-inch drill point diameter with a 118-degree drill point angle. At 6 inches overall length, it falls into the long-length category, giving technicians and machinists extra reach in deep or restricted workpieces. The plain cutting edge and double-end configuration add versatility and extended tool life between sharpenings.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is suited for metalworking applications where countersinking and center drilling must be completed efficiently in one pass. It is commonly used in fabrication shops, maintenance and repair operations, and production machining environments. The 90-degree included angle makes it appropriate for standard flat-head fastener seat preparation in steel, aluminum, and similar materials. Licensed tradespeople and machinists working with sheet metal assemblies, structural components, or general fabrication will find it a practical addition to a standard drill press or CNC setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombines drilling and countersinking into a single-pass operation, reducing setup time\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides hardness and wear resistance across common metals\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle is the standard geometry for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle prepares seats for flat-head machine screws and similar fasteners\u003c\/li\u003e\n  \u003cli\u003eDouble-end design extends usable tool life\u003c\/li\u003e\n  \u003cli\u003eLong-length at 6 inches overall allows access to recessed or deep workpiece locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use combination drill countersink for standard drill presses, CNC machining centers, and hand-held power drills accepting a 0.25-inch shank diameter tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tradespeople familiar with proper speeds and feeds for high-speed steel tooling. Secure the workpiece firmly before operation to prevent movement during cutting. Inspect the tool for chips or damage before each use, and do not exceed the recommended RPM range for the material being cut. Ensure the drill chuck is properly tightened to the 0.25-inch body diameter before starting the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 0.109 inches (7\/64)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 7\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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 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\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLong Length Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H-81155L03060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754021191986,"sku":"H-81155L03060","price":71.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc8cdc5e6a892dc61066f59115579e5e.jpg?v=1788943002","url":"https:\/\/voomisupply.com\/products\/hertel-h-81155l03060-combo-drill-countersink-hss-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
