Built to DIN 6537 standards, this bit features a 140-degree drill point angle, spiral flutes, and a web-thinned tapered web configuration that promotes self-centering and reduces thrust during entry. The FIREX coating provides heat and wear resistance, extending tool life in abrasive materials. At 4.50 mm (0.1772 inches) in diameter with a 102.00 mm overall length and a 12xD flute-to-diameter ratio, this bit is designed for deep-hole drilling with consistent accuracy. Right-hand cutting direction and a straight-cylindrical shank make it compatible with standard drill chucks and collet holders.\u003c\/p\u003e\u003cp\u003eThis bit is suited for machining cast iron and steel as primary workpiece materials, with secondary suitability for aluminum and titanium alloys. It is intended for use in CNC machining centers, drill presses, and manual machines where extended reach and tight tolerances are required. The coolant-through design supports internal coolant delivery, making it especially effective in production environments where chip evacuation and thermal management are critical. Machinists and tool-and-die professionals working in metal fabrication, mold making, and precision component manufacturing will find this bit suited to deep-feature drilling where standard-length tooling cannot reach.\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 heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with self-centering facet point geometry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant for chip evacuation and heat control\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting forces and entry thrust\u003c\/li\u003e\n\u003cli\u003eDIN 6537 standard compliant with right-hand spiral fluting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification solid carbide drill bit in the GUHRING Series 5525 line, suitable for use with standard straight-cylindrical shank toolholders, collets, and drill chucks sized to accept a 0.2362-inch shank diameter. Primary workpiece material codes K and P (cast iron and steel); secondary material codes H, M, N, and S (aluminum and titanium alloys).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with carbide tooling and machine setup. Secure the shank fully in the toolholder to the recommended grip depth before use, and verify runout before cutting. When using the internal coolant-through feature, confirm the machine spindle delivers coolant at a pressure compatible with this tool type. Carbide tooling is brittle — avoid impact or side-loading during setup and storage, and do not use this bit for interrupted cuts unless the machine setup is rigid and vibration-free.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.50 mm (0.1772 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 102.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 64.00 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\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 57.25 mm (2.2540 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: Yes\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\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 (K), Steel (P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Aluminum (N), Titanium Alloy (S, M, H)\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: California Prop 65, DIN 6537\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 9055250045000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735261086002,"sku":"9055250045000","price":376.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d6ea42eff4b42fd78a83a55789f5dca.jpg?v=1788771131","url":"https:\/\/voomisupply.com\/products\/guhring-9055250045000-extra-length-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
