Built to Series 5525 standards and finished with FIREX coating, it delivers heat and wear resistance in high-cycle production settings. The bit measures 3.80 mm (0.1495 inches) in diameter with an overall length of 90.00 mm and a flute length of 50.00 mm, giving it a 12xD flute-to-diameter ratio. A 140-degree drill point angle with web thinning and a self-centering facet point geometry promotes accurate entry and reduced thrust. Coolant-through capability supports chip evacuation and thermal management in deep-hole work. Cutting direction is right-hand, and the two-flute spiral design uses a regular helix for consistent chip flow.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production drilling in cast iron and steel as its primary workpiece materials, with secondary capability in aluminum and titanium alloys. The straight-cylindrical shank at 6.00 mm diameter and 36.00 mm shank length fits standard collet and drill chuck toolholding systems commonly found on CNC machining centers, drill presses, and manual mills. Maximum drilling depth is rated at 42.00 mm. It is well-matched to applications requiring tight positional accuracy and consistent hole quality in medium-to-high-volume metal fabrication, automotive, aerospace, and general machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and edge retention in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating provides elevated heat resistance and extended tool life in abrasive cutting conditions\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing and temperature control in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point with web thinning and facet point geometry enables self-centering and reduces entry thrust\u003c\/li\u003e\n  \u003cli\u003e12xD flute-to-diameter ratio accommodates deeper hole depths relative to drill diameter\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration and right-hand cutting direction conform to DIN 6537 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-grade replacement or direct-spec drill bit for straight-cylindrical shank toolholding systems; compatible with standard collets, drill chucks, and shrink-fit holders accepting a 6.00 mm shank. Primary workpiece materials are cast iron and steel (ISO material codes K and P); secondary workpiece materials include aluminum and titanium alloys (ISO codes H, M, N, and S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist or toolroom technician with the machine powered down and all energy sources locked out per applicable OSHA lockout\/tagout procedures. Ensure the toolholder bore is clean and free of debris before seating the shank to maintain runout tolerance. Coolant lines should be confirmed clear and delivering adequate flow before commencing deep-hole cycles. Do not exceed the rated maximum drilling depth of 42.00 mm without retracting for chip clearance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1495 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 3.80 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: 42.00 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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, Self-Centering\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\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\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\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: 9055250038000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727112012082,"sku":"9055250038000","price":376.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e656354e2c441a3c99943901a391634.jpg?v=1788673538","url":"https:\/\/voomisupply.com\/products\/guhring-9055250038000-extra-length-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
