Built from high speed steel with a bright uncoated finish, this bit measures 9 mm (0.3543 inches) in diameter and carries an overall length of 4-59\/64 inches (4.9219 inches). The 130-degree split point improves centering accuracy and reduces walking on entry. The web-thinned, tapered web construction lowers thrust requirements, while the parabolic flute geometry promotes efficient chip evacuation during deep-hole operations. Licensed machinists, tool-and-die workers, and maintenance technicians across manufacturing and fabrication environments rely on this style of bit for consistent, accurate results.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in CNC machining centers, drill presses, and hand-held power drills operating on aluminum and other K, N, and P material group workpieces as classified by cutting tool standards. The straight-cylindrical shank allows direct chuck mounting without adapters, making it compatible with standard three-jaw and keyless chucks in both benchtop and floor-model drill presses. Typical applications include hole production in structural aluminum plate, sheet metal, and light-duty steel components where parabolic flute geometry provides an advantage in chip control.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9 mm (0.3543 inches) diameter with tight diameter tolerance of -0.022 to 0.000 mm for precision hole sizing\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry with web thinning for reduced thrust and improved chip evacuation\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with standard point type for accurate entry and reduced walking\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated as high performance grade for extended tool life in target materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 specification for consistent geometry and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber length drill bit conforming to DIN 338, suitable for use in any standard drill press or CNC spindle accepting a 0.3543-inch straight shank. Primary workpiece materials are aluminum and non-ferrous metals (K, N, and P material groups per cutting tool classification).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist or maintenance technician using a standard three-jaw or keyless chuck. Always confirm the machine is powered off and the spindle is fully stopped before inserting or removing the bit. Secure the shank fully within the chuck jaws and verify concentricity before beginning a drilling cycle. Coolant-through is not supported on this bit; use external flood or mist coolant where required by the application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9 mm (0.3543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.9219 inches (125 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1875 inches (81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.657 inches (67.5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3543 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 44 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.022 to 0.000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (K, N, P material groups)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 549\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9005490090000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750551093554,"sku":"9005490090000","price":38.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec0f7e9ba60821d252d7276548c58085.jpg?v=1788916579","url":"https:\/\/voomisupply.com\/products\/guhring-9005490090000-jobber-drill-bit-9mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
