Built on the Series 5512 platform, it features a 0.1929 inch (4.90 mm) diameter, a 140-degree split-point (SU) tip, and a FIREX coating designed to extend tool life in hard and abrasive materials. The straight shank measures 6.00 mm in diameter, and the overall length is 90.00 mm with a 50.00 mm flute length at a 7xD ratio. Coolant-through construction supports high-speed, deep-hole drilling where chip evacuation and heat management are critical. A right-hand spiral flute with web thinning and parallel web configuration round out the geometry.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production machining environments where tight tolerances and consistent tool performance across difficult workpiece materials are required. The FIREX coating and submicron solid carbide grade make it appropriate for drilling stainless steel, hardened materials, nickel alloys, titanium alloys, cast iron, brass, and carbon steel. Typical install scenarios include CNC machining centers and manual drill press setups in aerospace, automotive, and general metal fabrication shops. The diameter tolerance of +0.004 to +0.016 mm supports precision bore requirements common in close-tolerance assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for high wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating reduces friction and heat buildup, extending tool life in stainless steel and nickel alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split-point tip improves self-centering and reduces thrust force at entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in deep-hole drilling cycles\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web geometry reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003e7xD flute-length-to-diameter ratio provides reach for taper-length drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drill presses accepting straight shank tooling with a 6.00 mm shank diameter.

Confirm chuck or collet bore matches the 6.00 mm straight shank diameter before clamping. Coolant-through setups require the machine spindle to be equipped with internal coolant delivery to take full advantage of the through-coolant design. Follow applicable shop safety standards and machine tool manufacturer guidelines when selecting feeds and speeds for the workpiece material.\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: 0.1929 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 4.90 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\u003eShank Diameter\u003c\/strong\u003e: 6.00 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\u003ePoint Type\u003c\/strong\u003e: SU (Split Point)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 7xD\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, 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\/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\u003eMaterial Application\u003c\/strong\u003e: Brass; Cast Iron; Hardened Materials; Nickel Alloy; Stainless Steel; Steel; Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5512\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 9055120049000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728067821874,"sku":"9055120049000","price":324.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcdfadd2296fea2710883e16c9cb0052_6cb85c1d-c3c3-4011-9997-ea1505418791.jpg?v=1788687336","url":"https:\/\/voomisupply.com\/products\/guhring-9055120049000-taper-length-drill-bit-0-1929-in","provider":"Voomi Supply","version":"1.0","type":"link"}
