Built from high-speed steel with a nitride finish and web-thinned construction, it delivers consistent chip evacuation and reduced thrust in demanding production environments. The parabolic flute geometry, combined with a tapered web configuration, supports efficient swarf removal at extended depths. With a 130-degree point angle, a flute length of 140 mm, and an overall length of 205 mm, this bit handles deep-reach operations that standard-length drills cannot reach. Licensed machinists, tool-and-die makers, and precision drilling technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for deep hole drilling operations where a 15xD flute-to-diameter ratio is required. Its primary target workpiece materials are aluminum and similar non-ferrous and low-alloy materials, consistent with the K, N, and P material codes in the DIN classification system. The straight-cylindrical shank fits standard drill chucks and collet holders used in CNC machining centers, drill presses, and manual lathes. The 65 mm shank length provides adequate grip for secure tool holding in high-performance setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParabolic flute geometry with tapered web for efficient chip evacuation in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned point reduces entry thrust and improves centering accuracy\u003c\/li\u003e\n\u003cli\u003e130-degree point angle suits aluminum and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003e15xD flute-to-diameter ratio enables drilling depths up to 131.75 mm\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1869 specification for extra length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1869-compliant extra length drill bit for use in standard straight-cylindrical chuck and collet systems on CNC machining centers, drill presses, and lathes where 5.5 mm diameter deep hole drilling is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and all energy sources locked out per applicable machine guarding standards. Confirm chuck or collet diameter matches the 5.5 mm straight-cylindrical shank before securing. Do not exceed the rated maximum drilling depth of 131.75 mm. Adequate cutting fluid or lubrication is recommended for extended tool life, particularly when drilling aluminum or non-ferrous alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.5 mm (0.2165 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 205 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 140 mm (5.512 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 65 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2165 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 131.75 mm (5.187 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Nitride\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Material Codes K, N, P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 502\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1869\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241637\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: 9005020055000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753136652594,"sku":"9005020055000","price":66.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6cda90adc81d3aea0e4167a92baa3f50.jpg?v=1788933164","url":"https:\/\/voomisupply.com\/products\/guhring-9005020055000-extra-length-drill-bit-5-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
