It carries a 0.4724-inch diameter, a 130-degree drill point angle, and a parabolic flute geometry that evacuates chips aggressively in long-reach cuts. The overall length is 295.00 mm (approximately 11.614 inches), with a flute length of 8.071 inches (205.00 mm) and a maximum drilling depth of 7.362 inches (187.00 mm). The shank is straight-cylindrical, matching the 0.4724-inch bit diameter, and the tool is left uncoated. It is manufactured to DIN 1869 standards and classified as a high-performance grade bit. HVAC fabricators, pipefitters, machinists, and maintenance mechanics install this type of tooling in production or field drilling setups.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for deep hole drilling in aluminum and similar non-ferrous and ferrous workpiece materials. Its parabolic flute profile and web-thinned, tapered web configuration reduce thrust and improve chip flow at extended depths. The 15xD flute-to-diameter ratio makes it well suited for through-hole and blind-hole applications where standard-length drills cannot reach. It cuts in a right-hand direction and is intended for use in drill presses, CNC machining centers, or hand-held power tools with an appropriate collet or chuck capable of accepting a 0.4724-inch straight shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 1869 extra length specification for deep hole reach up to 7.362 inches (187.00 mm)\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes aggressive chip evacuation in long-reach cuts\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drill point thrust and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction — uncoated, suitable for aluminum and similar materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle optimized for general-purpose and deep hole entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, straight-cylindrical shank for standard chuck or collet mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option conforming to DIN 1869 for extra length straight-shank drill bits used in deep hole drilling setups across metalworking and fabrication applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by a qualified machinist or skilled tradesperson familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and the tool holder is secure before inserting or removing the bit. Verify the chuck or collet is rated for the 0.4724-inch shank diameter and that cutting speeds and feeds are appropriate for the workpiece material per standard machining practice. Do not exceed the rated maximum drilling depth of 7.362 inches without verifying adequate chip clearance and coolant strategy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 295.00 mm (approximately 11.614 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.071 inches (205.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 7.362 inches (187.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 90.00 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\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: Uncoated\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1869\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 502\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Deep Hole Drilling\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: 9005020120000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734698230066,"sku":"9005020120000","price":186.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5de896e6e9503d8a486cf1730080800d.jpg?v=1788765181","url":"https:\/\/voomisupply.com\/products\/guhring-9005020120000-extra-length-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
