Manufactured from high speed steel (HSS) with a bright, uncoated finish, this bit features a parabolic flute geometry and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The 130-degree split point is suited for accurate starting and clean entry without a center punch in many applications. With an overall length of 3-31\/32 inches and a flute length of 2-15\/32 inches, this drill is intended for use in drill presses, CNC machines, and handheld drilling equipment by machinists, maintenance technicians, and trade professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated as a high-performance grade and conforms to DIN 338 standards. It is primarily designed for aluminum and non-ferrous materials, as indicated by workpiece material codes K, N, and P. The parabolic flute profile supports efficient chip clearing in through-hole and deep drilling scenarios. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 2.0890 inches (53.06 mm), it fits standard drilling operations in light manufacturing, HVAC fabrication, plumbing rough-in, and general mechanical service environments. The straight-cylindrical shank measures 0.2610 inches in diameter and is compatible with standard drill chucks and collet holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter G size with 0.2610 inch decimal equivalent for precise bore sizing\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast chip evacuation and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web lowers cutting resistance and entry thrust\u003c\/li\u003e\n\u003cli\u003e130-degree point angle provides accurate positioning and clean hole entry\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 standard for jobber-length HSS drill bits\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for aluminum, plastics, and soft metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 338-compliant jobber-length drill bit optimized for aluminum and non-ferrous workpiece materials (material codes K, N, P), suitable for use in standard drill chucks and collet systems accepting a 0.2610 inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with drilling equipment safety. Secure the shank fully in the chuck or collet before operation and verify chuck runout is within tolerance to protect the cutting edge. Do not exceed the recommended drilling depth of 2.0890 inches without retracting to clear chips. Use appropriate cutting fluid for the workpiece material when drilling in production environments to extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-31\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-15\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.0890 inches (53.06 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 38.00 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Codes K, N, P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 549\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: 9005490066300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728669212978,"sku":"9005490066300","price":34.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04481786ca0bdb709bdf7cc4dfec9bf8.jpg?v=1788694684","url":"https:\/\/voomisupply.com\/products\/guhring-9005490066300-drill-bit-letter-g-0-261-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
