Built to Series 559 standards, it features a 0.5000-inch cutting diameter with a matching 0.5000-inch straight cylindrical shank, and a bright uncoated finish suited for general-purpose shop use. The overall length measures 6.2656 inches with a 1.1800-inch flute length. The two-spiral-flute, single-ended design supports right-hand cutting and delivers consistent spot geometry across ferrous and non-ferrous workpiece materials. Licensed machinists, tool-and-die techs, and production drilling setups are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis spotting drill is intended for general-purpose spotting applications across metalworking environments including job shops, maintenance facilities, and production floors. It is used to establish accurate drill starts, reduce walking on flat or angled surfaces, and improve hole-location accuracy before full-depth drilling. The 90-degree point angle aligns with standard countersink and center-drill conventions, making it a practical fit for conventional machining centers, drill presses, and CNC setups running through coolant or dry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree drill point angle for accurate spot starts and countersink compatibility\u003c\/li\u003e\n  \u003cli\u003e0.5000-inch cutting diameter with matching straight cylindrical shank for direct collet or chuck mounting\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for general-purpose durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for re-sharpening and inspection of wear\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with right-hand cut for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSingle-ended design with 1.1800-inch flute length for shallow, precise spot geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose spotting drill for use in standard 1\/2-inch collets, drill chucks, or tool holders on conventional and CNC machining equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSpotting drills are installed by machinists and tool-and-die technicians using standard collet or drill chuck setups. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Verify runout with a dial indicator after seating the shank to confirm concentricity before cutting. Follow the machine manufacturer and OSHA applicable guidelines for RPM and feed selection based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.2656 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eSingle\/Double Ended\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 559\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Spotting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005590127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749145936178,"sku":"9005590127000","price":126.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39429a7a7a20cd42c69f7070878171d7.jpg?v=1788902605","url":"https:\/\/voomisupply.com\/products\/guhring-9005590127000-spotting-drill-90-degree-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
