Built from high-speed steel (HSS) with a bright, uncoated finish, it features a parabolic flute geometry and a 130-degree split point for fast, accurate entry without a center punch. The web-thinned, parallel-web design reduces thrust load and improves chip evacuation. With an overall length of 1.26 inches and a flute length of 0.3543 inches, this bit is sized for use in screw machine chucks, CNC lathes, and short-stroke drilling operations. It conforms to DIN 1897 standards and is rated as a high-performance grade tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is optimized for drilling aluminum as its primary workpiece material, though the HSS construction handles a range of non-ferrous and ferrous materials encountered in production machining and precision fabrication. The stub-length format provides added rigidity compared to jobber-length bits, making it well suited for high-speed, high-volume drilling on CNC equipment, drill presses, and screw machines where runout and deflection must be minimized. The right-hand cut and straight-cylindrical shank ensure compatibility with standard ER collets, drill chucks, and quick-change toolholding systems common in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS construction with bright, uncoated finish for general-purpose and aluminum drilling\u003c\/li\u003e\n\u003cli\u003e130-degree split point promotes self-centering and reduces walking on entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile improves chip flow and reduces heat buildup in deep passes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel-web design lowers required thrust and extends tool life\u003c\/li\u003e\n\u003cli\u003eStub-length body adds rigidity and reduces deflection versus jobber-length alternatives\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 specification for dimensional consistency across the series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length drill bit for use in standard drill chucks, ER collet systems, and quick-change toolholders accepting straight-cylindrical shanks in the 0.0531-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist or tooling technician; secure the straight-cylindrical shank firmly in a collet or drill chuck before use and verify runout with a dial indicator on precision setups. Always power down and de-energize the machine spindle before changing tooling. Use appropriate cutting fluid or mist coolant when drilling aluminum to manage chip welding, even though the tool does not support through-coolant delivery. Follow OSHA machine guarding requirements and the equipment manufacturer's speed-and-feed recommendations for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0531 inches (1.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.26 inches (32.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.3543 inches (9.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.2750 inches (6.98 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 9005520013500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732080918834,"sku":"9005520013500","price":106.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dcc6a6ceaf4e98533d679b4ab2f2224.jpg?v=1788738988","url":"https:\/\/voomisupply.com\/products\/guhring-9005520013500-stub-drill-bit-0-0531-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
