Built from high-speed steel (HSS) with a bright uncoated finish, it features a 1\/8 inch body diameter and a 3\/64 inch drill point diameter with a 118-degree drill point angle. The 82-degree included angle on the countersink portion is sized for standard flat-head fastener seating. At 4 inches overall length, this is a long-length tool suited for reaching into workpieces where a standard-length tool falls short. Machinists, tool-and-die technicians, and metalworking tradespeople use this style of tool to eliminate a secondary countersinking step on drilled holes.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is used in metalworking applications where a pilot hole and countersink must be produced in one pass. It is appropriate for light-duty metals, sheet stock, and fabrication work in trade or production shop environments. The plain cutting edge style and double-end configuration make it a general-purpose workhorse for countersinking flat-head fastener holes. The long-length design provides additional reach for workpieces with limited accessibility from standard toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombines drilling and countersinking into a single tool operation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in metalworking applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eDouble-end design extends tool life by providing two usable ends\u003c\/li\u003e\n  \u003cli\u003eLong-length at 4 inches overall for extended reach applications\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle sized for standard flat-head fastener seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard shop tool for metalworking operations requiring a No. 1 trade size combination drill countersink with a 1\/8 inch body diameter and 82-degree included angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed in a drill press, lathe tailstock, or compatible rotary toolholder by a machinist or metalworking technician. Ensure the machine is powered down and the spindle is fully stopped before changing tooling. Use appropriate RPM for the workpiece material and tool diameter per standard machining reference tables. Do not use on materials or at feeds and speeds beyond the rated capacity of high-speed steel tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 3\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 3\/64 inch\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: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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\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-81154L01040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731921043762,"sku":"H-81154L01040","price":47.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f147a01935015e6b84ca1d8c6d4002d7.jpg?v=1788736637","url":"https:\/\/voomisupply.com\/products\/hertel-h-81154l01040-combo-drill-countersink-1-8-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
