Built from high speed steel with a bright uncoated finish, it features a parabolic flute geometry and a 130-degree point angle optimized for fast chip evacuation and accurate hole entry. The bit measures 0.1831 inches (4.65 mm) in diameter with an overall length of 2.2835 inches (58.00 mm) and a flute length of 0.9450 inches (24.00 mm). A web-thinned, parallel web configuration reduces thrust and improves centering. This bit is installed and used by machinists, tool-and-die professionals, and maintenance technicians working with precision drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling aluminum as its primary workpiece material, though the high speed steel construction handles a broad range of non-ferrous and softer ferrous materials in short-hole applications. The stub length format makes it ideal for rigid setups in drill presses, CNC machining centers, and screw machine operations where minimal overhang and high accuracy are required. Maximum drilling depth is 0.6700 inches (17.03 mm), consistent with its 3xD flute-to-diameter ratio. The straight cylindrical shank fits standard drill chucks and collet systems without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParabolic flute geometry promotes efficient chip evacuation and reduces heat buildup during drilling\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle provides fast penetration and self-centering on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces axial thrust and improves drill bit longevity\u003c\/li\u003e\n  \u003cli\u003eStub length construction increases rigidity and minimizes deflection in close-tolerance work\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.018 mm ensures consistent hole sizing within DIN 1897 specification\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose use without additional surface treatment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eManufactured to DIN 1897 specification (Series 552), this stub drill bit is compatible with any standard drill chuck or collet system accepting a straight cylindrical shank at 0.1831 inches (4.65 mm) diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with drill press, lathe, or CNC equipment operation. Ensure the machine spindle and workpiece are fully secured before beginning any drilling operation. Use appropriate cutting fluid or coolant when drilling ferrous materials or high-cycle production runs to extend tool life, noting this bit does not support internal coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace the bit if diameter tolerance can no longer be maintained.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1831 inches (4.65 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.2835 inches (58.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.9450 inches (24.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6700 inches (17.03 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: 3xD\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 9005520046500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51746596258098,"sku":"9005520046500","price":23.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c814c72cb55cb7bb9a0b29c3f184da81.jpg?v=1788871607","url":"https:\/\/voomisupply.com\/products\/guhring-9005520046500-stub-drill-bit-0-1831-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
