Built from high-speed steel with a bright uncoated finish, this tool is engineered for trade and industrial use in metal fabrication, machining, and assembly applications. It features a 3\/16 inch drill point diameter, a 118-degree drill point angle, and an 82-degree included angle for the countersink profile. At 6 inches overall length, it qualifies as a long-length tool, making it well suited for work in recessed or harder-to-reach setups. Machinists, tool-and-die techs, and fabricators are the primary users.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is used in applications requiring a pre-drilled pilot hole and countersink seat in one pass, reducing setup time on drill presses, CNC machining centers, and manual milling machines. It is sized for trade size 5 work with a 7\/16 inch body diameter and a 3\/16 inch drill point. The plain cutting edge style and non-tapered, non-insertable design make it a straightforward drop-in tool for standard countersinking tasks. It is appropriate for use in ferrous and non-ferrous metals where a clean countersink seat is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombination drill and countersink completes pilot drilling and countersinking in one pass\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a range of metal workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suits general-purpose use without added coating cost\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle paired with 82-degree included angle for standard countersink profiles\u003c\/li\u003e\n\u003cli\u003eLong-length design at 6 inches OAL allows access in deeper or recessed work areas\u003c\/li\u003e\n\u003cli\u003eDouble end type maximizes tool life by providing two usable ends\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill press chucks, CNC spindles, and manual machine tool holders accepting a 7\/16 inch body diameter shank for trade size 5 combination drill countersink applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist or tool operator familiar with speeds and feeds for high-speed steel cutting tools. Ensure the spindle is fully stopped and power is disconnected before changing or securing the tool in the holder. Use appropriate work-holding and eye protection per shop safety standards. Do not exceed the recommended RPM range for the workpiece material to avoid premature tool wear or breakage.\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\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: 82 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\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-81154L05060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737372066098,"sku":"H-81154L05060","price":78.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/841bdf3ea438da114ebcfc3595362ff0.jpg?v=1788787737","url":"https:\/\/voomisupply.com\/products\/hertel-h-81154l05060-combo-drill-countersink-hss-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
