Built to DIN 338 standards, this bit features a 7.2 mm diameter, a 118-degree four-facet split-point tip, and a right-hand spiral flute configuration. The M35 cobalt material grade provides elevated heat resistance compared to standard high-speed steel, making it suitable for harder and more abrasive workpiece materials. Overall length is 109 mm with a flute length of 69 mm and a maximum drilling depth of 58.2 mm.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for machining aluminum, steel, stainless, and cast iron workpiece materials, corresponding to material codes K, M, N, and P. It fits conventional drill presses, CNC machining centers, and handheld power tools accepting a straight-cylindrical shank. The 7.2 mm straight-cylindrical shank with a 40 mm shank length seats securely in standard collets and drill chucks. The Series 5519 designation places it within a consistent Guhring product family, allowing straightforward reorder and tooling standardization for shops running metric drill programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point reduces thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute with web-thinned, tapered web for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 standard; diameter tolerance of +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e5xD flute-to-diameter ratio; no coolant-through required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with workpiece materials in material code groups K, M, N, and P, including aluminum, steel, stainless steel, and cast iron.

Power down and lock out the machine spindle before inserting or removing the bit from the chuck or collet. Ensure the chuck or collet is clean and free of debris to maintain concentricity and achieve the rated diameter tolerance. Do not exceed the recommended maximum drilling depth of 58.2 mm in a single pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.2 mm (0.2835 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 109 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 69 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 58.2 mm (2.291 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.2 mm (0.2835 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet, Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt Steel, M35 Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5519\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 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: 9055190072000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748733419826,"sku":"9055190072000","price":29.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc2796606b86affad3ece68d198f005a_5f6844e0-b065-4e0c-b8f5-0be40482d85f.jpg?v=1788897478","url":"https:\/\/voomisupply.com\/products\/guhring-9055190072000-cobalt-jobber-drill-bit-7-2-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
