It measures 5.90 mm in diameter with an overall length of 93.00 mm and a flute length of 57.00 mm. The 118-degree cone relief point provides a conventional cutting geometry suitable for a wide range of materials. The bright, uncoated finish is standard for cobalt-grade tooling and supports use with or without cutting fluid. Web thinning reduces thrust requirements at the cutting center, making starts cleaner on flat and curved surfaces. This bit is used by machinists, maintenance technicians, pipefitters, and general fabricators working with drill presses, CNC machines, or portable power tools.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance drilling applications in metal fabrication shops, mechanical contractors, and industrial service environments. The regular spiral geometry and right-hand cutting direction make it compatible with standard drill chucks and spindles. The 5xD flute-to-diameter ratio provides adequate chip evacuation for through-hole drilling at typical jobber depths. It is manufactured to DIN specification, ensuring consistent dimensional tolerances across the cutting diameter and shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5.90 mm cutting diameter with matching 5.90 mm straight shank for consistent chuck fit\u003c\/li\u003e\n\u003cli\u003e118-degree cone relief point angle for conventional general-purpose drilling geometry\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance versus standard HSS\u003c\/li\u003e\n\u003cli\u003eWeb-thinned point reduces axial cutting force and improves centering on entry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with most cutting fluids and dry drilling conditions\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute with 2-flute configuration for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill for use in standard drill chucks and spindles accepting a 5.90 mm straight shank, suitable for drill presses, CNC drilling centers, and hand-held power tools within the 5.00 mm to 6.00 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician familiar with rotating cutting tool safety. Secure the shank fully within the chuck jaws and confirm runout is within acceptable limits before engaging the workpiece. De-energize and lock out the machine spindle before changing or inspecting the bit. Do not use this bit in reverse rotation or in applications requiring left-hand cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.90 mm (0.2323 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 93.00 mm (3.661 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 57.00 mm (2.244 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.90 mm (0.2323 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\u003ePoint Type\u003c\/strong\u003e: Cone Relief\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, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt 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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9003050059000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51971370025266,"sku":"9003050059000","price":18.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d92e13879f09a076e8541f50cdf4eb5_621a2820-00e8-42cb-8608-8100b407705d.jpg?v=1789955985","url":"https:\/\/voomisupply.com\/products\/guhring-9003050059000-cobalt-jobber-drill-5-90mm","provider":"Voomi Supply","version":"1.0","type":"link"}
