It carries a 0.3346 inch (8.50 mm) diameter with a parabolic flute design and a 130-degree point angle that aids chip evacuation and reduces thrust in demanding materials. The straight-cylindrical shank seats securely in standard drill chucks and collets. At a total flute length of 6.496 inches (165 mm) and a maximum drilling depth of 5.994 inches (152.25 mm), this bit reaches depths that standard length drills cannot. It is uncoated high-speed steel with a web-thinned, tapered web configuration. Machinists and tool and die professionals are the primary installers.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for deep hole drilling in aluminum and other non-ferrous and ferrous workpiece materials. The parabolic flute geometry promotes efficient chip removal during extended-depth passes, reducing the need for peck-drilling cycles. With a flute-to-diameter ratio of 15xD and a right-hand cutting direction, it suits CNC machining centers, knee mills, and drill presses where consistent hole quality at depth is required. It conforms to DIN 1869 standards, making it a direct fit in applications specifying that designation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.3346 inch (8.50 mm) diameter per DIN 1869 specification\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes chip evacuation in deep hole passes\u003c\/li\u003e\n\u003cli\u003e130-degree point angle reduces thrust and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting resistance at the tip\u003c\/li\u003e\n\u003cli\u003e15xD flute-to-diameter ratio enables drilling to 5.994 inches depth\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, 2-flute configuration for standard machine tool setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1869 Series 502 extra length drill bit suited for deep hole drilling operations in aluminum (material code K, N, P workpieces) using standard straight-cylindrical shank toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with deep hole drilling procedures. Secure the straight-cylindrical shank fully in a properly sized collet or drill chuck before operation, and verify runout is within acceptable limits for the application. Power down and de-energize the machine spindle before changing tooling. Consult machine tool manufacturer feed and speed recommendations for the workpiece material — do not exceed the rated maximum drilling depth of 5.994 inches for this bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3346 inches (8.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 240.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.496 inches (165.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 5.994 inches (152.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3346 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 75.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\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\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\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: 9005020085000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735488364850,"sku":"9005020085000","price":132.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47a6c18e3734a72f17c19832d9eb8e33_6673c436-206b-409d-9762-5bacc2d9b96c.jpg?v=1788772683","url":"https:\/\/voomisupply.com\/products\/guhring-9005020085000-extra-length-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
