Built to Series 5525 specifications, it features a 3.2 mm diameter, a 140-degree drill point angle, and a FIREX coating that extends tool life in demanding applications. The submicron carbide grade provides superior hardness and edge retention compared to standard carbide grades. Coolant-through capability supports chip evacuation and thermal management during deep-hole drilling. Licensed HVAC, plumbing, electrical, and industrial trade professionals use this bit where precision and tool longevity are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling cast iron and steel as primary workpiece materials, with secondary capability in aluminum and titanium alloys. The 12xD flute-to-diameter ratio and 50 mm flute length make it appropriate for extended-reach drilling scenarios where a standard-length bit cannot reach the bore. The straight-cylindrical shank fits standard drill chucks and collet holders with a 6 mm shank diameter, and the right-hand spiral flute geometry promotes consistent chip removal in production and maintenance environments alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron grade construction for high hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eFIREX coating improves wear resistance and heat management during extended drilling cycles\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in deep-hole applications up to 43 mm drilling depth\u003c\/li\u003e\n  \u003cli\u003e140-degree facet point with web thinning provides self-centering entry and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003e12xD flute-by-diameter ratio enables extended-reach drilling beyond standard bit capability\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral, tapered web configuration maintains rigidity while improving chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a 6 mm straight-cylindrical shank.

Ensure the machine spindle and chuck or collet are clean and properly torqued before seating the shank. When using the coolant-through feature, verify that coolant supply pressure and flow rate match the machine tool specifications before starting the cut. Do not exceed the maximum drilling depth of 43 mm per the Series 5525 design parameters, and always allow the bit to reach full RPM before contact with the workpiece to prevent chipping the carbide tip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.2 mm (0.1260 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 90 mm (3.54 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 50 mm (1.97 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43 mm (1.69 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.236 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.42 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Facet Point Grinding, Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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\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\u003eStandard\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 9055250032000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":67911246905650,"sku":"9055250032000","price":379.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bc81ba71e8fca0906836129110d9210.jpg?v=1791207692","url":"https:\/\/voomisupply.com\/products\/guhring-9055250032000-extra-length-drill-bit-3-2-mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
