Built to Series 5525 specifications, it features a 11.00 mm (0.4331 inches) cutting diameter, a 140-degree drill point angle, and a FIREX coating for extended tool life in demanding applications. The overall length is 204.00 mm with a flute length of 156.00 mm, giving it a 12xD flute-by-diameter ratio suited for deep-hole work. Coolant-through capability supports chip evacuation and heat management. Licensed HVAC technicians, machinists, and industrial maintenance professionals working with CNC or manual equipment rely on this bit for consistent hole quality in tight-tolerance applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for primary use in cast iron and steel (ISO material codes K and P). Secondary workpiece materials include aluminum and titanium alloy (ISO codes H, M, N, and S). The web-thinned, tapered web configuration and self-centering facet point make it appropriate for precision work where a pilot hole is not always practical. It is well suited for production drilling environments where tool rigidity and coating durability reduce cycle times and tool changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eFIREX coating extends service life in cast iron, steel, aluminum, and titanium alloy\u003c\/li\u003e\n  \u003cli\u003e140-degree split point with facet grind for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design channels fluid directly to the cutting edge for deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting force and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, spiral flute, straight-cylindrical shank for standard tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct application drill bit conforming to DIN 6537 standards, with a 0.4724-inch straight-cylindrical shank compatible with standard drill chucks and collet holders sized for that shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or maintenance professionals familiar with CNC or manual drilling equipment. Before mounting or changing tooling, ensure the machine spindle is fully de-energized and at a complete stop. Confirm the tool holder or collet is clean and properly torqued according to the machine manufacturer specifications before running. Coolant-through tooling requires a compatible through-spindle coolant system; verify coolant pressure and flow rate match the tool and material requirements before beginning a drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.00 mm (0.4331 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 204.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 156.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 139.50 mm (5.4920 inches)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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, Facet Point, Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel (ISO K, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Aluminum, Titanium Alloy (ISO H, M, N, S)\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 Proposition 65\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\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: 9055250110000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755396530482,"sku":"9055250110000","price":736.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7878a8d740abd916bdc46247c5df6e03_f7fe0926-9921-43a4-a01a-9957fe33b2a1.jpg?v=1788954538","url":"https:\/\/voomisupply.com\/products\/guhring-9055250110000-extra-length-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
