Built from high-speed steel with a bright, uncoated finish, this tool handles light-to-medium drilling and countersinking tasks in metal, wood, and plastics. It carries a trade size of 5 with a 7\/16-inch body diameter and an overall length of 2.75 inches. The 118-degree drill point angle and 3\/16-inch point diameter make it a practical choice for machinists, fabricators, and maintenance technicians working with screw clearance and countersink prep on standard fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is suited for use in manual drill presses, CNC lathes, and bench-mounted setups where consistent countersink geometry is required. The 90-degree included angle matches the seat geometry for flat-head fasteners commonly used in sheet metal and structural fabrication. With a double-end configuration, the tool provides extended service life by offering two usable ends before replacement. It is appropriate for production shops and field maintenance operations where high-speed steel tooling is preferred for cost-effective, general-purpose cutting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across metal, wood, and plastic materials\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle matches standard flat-head fastener countersink geometry\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for clean entry and accurate pilot hole formation\u003c\/li\u003e\n  \u003cli\u003eDouble-end design extends tool life with two usable cutting ends\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n  \u003cli\u003eCompact 2.75-inch overall length fits standard drill press and lathe setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose combination drill and countersink for use with standard drill presses, CNC lathes, and rotary toolholding systems that accept straight-shank cutting tools.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and fabricators in drill press or lathe toolholding collets rated for straight-shank tooling. Ensure the workpiece is securely clamped and the spindle is at a complete stop before changing or adjusting the tool. Use appropriate cutting fluid for ferrous metals to reduce heat buildup and extend cutting edge life. Follow shop safety practices and applicable OSHA general industry standards when operating rotary cutting equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 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\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\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-81155050000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735145251122,"sku":"H-81155050000","price":30.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d818a63094cfd3ff246f60dcba78dcdf.jpg?v=1788769852","url":"https:\/\/voomisupply.com\/products\/hertel-h-81155050000-combo-drill-countersink-size-5-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
