Built from submicron-grade carbide and coated with FIREX for extended tool life and heat resistance, this bit measures 10.00 mm (0.3937 inches) in diameter with an overall length of 162.00 mm. The 140-degree drill point angle and web-thinned, tapered web construction promote self-centering and reduce thrust forces at entry. A coolant-through design channels cutting fluid directly to the tip, making it well suited for deep-hole applications where chip evacuation and thermal management are critical. Spiral flutes with right-hand cutting direction complete the geometry. This is a professional-grade tool for machine shop and industrial drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in CNC machining centers, drill presses, and other rigid machine setups where extended reach and tight tolerances are required. Primary workpiece materials include cast iron and steel (ISO material codes K and P). Secondary suitable materials include aluminum, titanium alloy, and other ISO codes H, M, N, and S. The 12xD flute-to-diameter ratio supports drilling depths up to 105.00 mm (4.1340 inches), making it appropriate for through-hole and deep blind-hole applications in both production and toolroom settings. The straight-cylindrical shank seats in standard collet chucks and drill chucks without special adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for rigidity and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003eFIREX coating provides thermal barrier and reduces built-up edge on ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eCoolant-through channels deliver cutting fluid directly to the cutting edge for deep-hole drilling\u003c\/li\u003e\n\u003cli\u003e140-degree facet point with web thinning enables self-centering and reduces entry thrust\u003c\/li\u003e\n\u003cli\u003e12xD flute-to-diameter ratio supports drilling depths up to 105.00 mm\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flutes with tapered web for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series 5525 OEM-specification drill bit for use in rigid machine tool setups requiring a 10.00 mm straight-cylindrical shank. Suitable for primary workpiece materials cast iron and steel (ISO K, P) and secondary materials aluminum and titanium alloy (ISO H, M, N, S) per DIN 6537 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Secure the straight-cylindrical shank in a properly sized collet chuck or drill chuck, ensuring full shank engagement to the specified 40.00 mm shank length before tightening. Verify that machine spindle speed and feed rate are set according to the workpiece material and cutting data tables before operation. Do not use this bit in handheld drilling equipment; rigid machine mounting is required to maintain diameter tolerance of +0.006 to +0.021 mm.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 162.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 120.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 105.00 mm (4.1340 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 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\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\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\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\u003eDiameter 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 (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: 0.26 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: 9055250100000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738753925426,"sku":"9055250100000","price":694.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7878a8d740abd916bdc46247c5df6e03_284f4709-b8dd-4c7d-bdbd-41b606ff8fae.jpg?v=1788803899","url":"https:\/\/voomisupply.com\/products\/guhring-9055250100000-extra-length-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
