It measures 3.10 mm (0.122 inches) in diameter with an overall length of 90.00 mm and a flute length of 50.00 mm, providing extended reach where standard-length drills fall short. The FIREX coating delivers enhanced wear resistance and thermal stability, extending tool life in abrasive materials. A 140-degree drill point angle combined with web thinning and a standard point type promotes accurate entry and reduced thrust force. This bit is designed for use by machinists and tool-and-die professionals working in CNC and conventional drilling applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron and steel as primary workpiece materials, with secondary capability in aluminum and titanium alloys. It is a Series 5525 tool with a 12xD flute-to-diameter ratio, making it appropriate for deep-hole drilling cycles where chip evacuation and rigidity are critical. The maximum drilling depth is 43.00 mm. Coolant-through capability supports high-speed drilling cycles with through-spindle coolant systems commonly found in machining centers and CNC drilling equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eFIREX coating for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with through-spindle coolant delivery\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with web thinning for self-centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 6.00 mm diameter for standard collet or chuck mounting\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute with tapered web configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application drill bit for use in machining centers, CNC drill presses, and conventional drilling equipment accepting a 6.00 mm straight-cylindrical shank.

Ensure the collet or chuck bore matches the 6.00 mm shank diameter before tightening. Verify through-spindle coolant pressure and flow rate are configured per machine specifications before running at full feed and speed. Handle solid carbide tooling carefully to avoid chipping the cutting edges during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.122 inches (3.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 90.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 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: 9055250031000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747776102706,"sku":"9055250031000","price":378.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd1cac4a172101257b90cbab7afe4f51.jpg?v=1788885339","url":"https:\/\/voomisupply.com\/products\/guhring-9055250031000-extra-length-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
