Built to DIN 1869 standards, this Series 502 bit features a parabolic flute design and a web-thinned, tapered web configuration that promotes efficient chip evacuation in deep-bore operations. The straight-cylindrical shank measures 0.4921 inches in diameter, matching the cutting diameter for a consistent grip in standard drill chucks and collets. With a flute length of 8.071 inches and a maximum drilling depth of 7.333 inches, this bit is suited to operations where a standard-length drill simply cannot reach. It is installed and used by machinists and maintenance technicians working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for deep hole drilling in aluminum and other non-ferrous and ferrous workpiece materials, consistent with its K, N, and P material group ratings. The 15xD flute-to-diameter ratio supports extended-reach drilling in applications where standard-length bits fall short. The 130-degree split point and web-thinned tip reduce entry thrust and help maintain hole position. It cuts right-hand and is intended for use without coolant-through capability, making it compatible with conventional drill press, milling machine, and CNC machining center setups that rely on external flood or mist cooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDIN 1869 specification for extra length drill bit geometry and tolerances\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes chip flow and reduces packing in deep holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces cutting thrust at entry\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle for aggressive penetration and accurate starting\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.027 mm for controlled hole sizing\u003c\/li\u003e\n  \u003cli\u003eUncoated HSS construction suited to aluminum and general-purpose deep-hole work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Series 502 extra length drill bit per DIN 1869, suited for use in drill presses, milling machines, and CNC machining centers requiring deep-reach boring capability in aluminum and compatible workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified maintenance technicians. Secure the straight-cylindrical shank firmly in a compatible drill chuck or collet before operation, and verify runout with an indicator when tight tolerances are required. Power down and de-energize the machine fully before changing tooling. Because this bit does not have coolant-through capability, apply appropriate external flood or mist coolant during deep-hole operations to prevent heat buildup and premature wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4921 inches (12.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 295.00 mm\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: 7.333 inches (186.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4921 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\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.027 mm\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\u003eTool Application\u003c\/strong\u003e: Deep Hole Drilling\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\u003ePoint Type\u003c\/strong\u003e: Standard\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: 9005020125000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738254278962,"sku":"9005020125000","price":235.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b488c428f3494966082fe5e04b69aa80.jpg?v=1788797334","url":"https:\/\/voomisupply.com\/products\/guhring-9005020125000-extra-length-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
