Built to DIN 6537 standards, it carries a FIREX coating for extended tool life and heat resistance. The bit measures 0.2813 inches (8.00 mm) in diameter with an overall length of 146.00 mm, a flute length of 108.00 mm, and a maximum drilling depth of 93.00 mm. The 140-degree drill point angle and web-thinned, tapered web geometry promote accurate entry and reduced thrust. Coolant-through capability supports chip evacuation in deep-hole applications. Licensed HVAC techs, machinists, and production drillers working in ferrous and non-ferrous materials will find this a capable production tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron and steel as its primary workpiece materials, with aluminum and titanium alloy listed as secondary applications. The 12xD flute-to-diameter ratio makes it appropriate for extended-reach operations where a standard-length bit cannot reach. The straight-cylindrical shank and 8.00 mm shank diameter allow it to seat in standard collet chucks and drill chucks without adapters. It is appropriate for CNC machining centers, drill presses, and manual milling setups where precision and depth are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eFIREX coating for elevated temperature and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eCoolant-through design to assist chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with web-thinned, tapered web for self-centering entry\u003c\/li\u003e\n\u003cli\u003e12xD flute-to-diameter ratio enabling a maximum drilling depth of 93.00 mm\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537 standard; right-hand cutting with regular spiral flute\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit drill bit for applications requiring a 0.2813-inch diameter solid carbide extra length drill in Series 5525 per DIN 6537. Primary workpiece materials are cast iron and steel (ISO material codes K and P); secondary materials include aluminum and titanium alloy (ISO codes H, M, N, and S).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a properly sized collet chuck or drill chuck rated for the 8.00 mm shank diameter; confirm runout is within tolerance before use. Power down and lock out the machine spindle before changing tooling. Follow the machine tool manufacturer's recommended feed and speed parameters for carbide tooling in the target workpiece material. Handle carbide tools carefully to avoid chipping the cutting edge during storage and setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 146.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 108.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 93.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 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: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Aluminum, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5525\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6537, California Prop 65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 9055250071400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730007261490,"sku":"9055250071400","price":450.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74516e89809641a6c380cf62d2b9e49f.jpg?v=1788710076","url":"https:\/\/voomisupply.com\/products\/guhring-9055250071400-extra-length-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
