The bit features a 118-degree four-facet split point with web thinning for fast, accurate hole starts and reduced thrust. A titanium nitride (TiN) coating extends cutting life by increasing surface hardness and reducing friction. With a straight-cylindrical shank measuring 5.11 mm in diameter and a 2-flute regular spiral configuration, it is compatible with standard drill chucks. This bit is installed by machinists, maintenance technicians, and skilled tradespeople working in metal fabrication and general-purpose drilling applications.\u003c\/p\u003e\n\u003cp\u003eThe 9055190051100 is suited for drilling aluminum, steel, stainless, and a range of ferrous and non-ferrous metals, reflecting its K, M, N, and P workpiece material codes per DIN 338 classification. It is designed for use in benchtop drill presses, milling machines, and hand-held power drills where a jobber length reach is appropriate. The overall length of 86 mm and a flute length of 52 mm provide a 5xD flute-to-diameter ratio, giving it adequate chip clearance for depths up to approximately 44.34 mm. This makes it a practical replacement or stocking bit for tool cribs and service vehicles handling general metalworking tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 7 wire size, 0.2010 inches decimal diameter with tolerance of +0.000 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003eM35 cobalt material grade with TiN coating for extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point with web thinning reduces walking and entry thrust\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral, right-hand cut, 5xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with straight-cylindrical shank for broad chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 specification for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338 jobber length replacement drill bit suitable for standard drill chucks accepting a 5.11 mm straight-cylindrical shank, appropriate for use across aluminum, low-alloy steel, stainless steel, and non-ferrous metals as defined by DIN workpiece material codes K, M, N, and P.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and maintenance tradespeople using standard drill chucks on drill presses, CNC equipment, or portable power drills. Secure the shank fully in the chuck before operation and verify chuck key is removed. Use cutting fluid or coolant appropriate to the workpiece material to preserve coating life, as this series does not support coolant-through delivery. Inspect the cutting edges before each use and replace when chipping or dulling is observed to maintain hole tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M35 Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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 Point\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\u003eOverall Length\u003c\/strong\u003e: 86 mm (approximately 3.39 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 52 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.11 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 34 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 44.34 mm (1.746 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003ePackage Weight\u003c\/strong\u003e: 0.022 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9055190051100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750015205682,"sku":"9055190051100","price":21.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc2796606b86affad3ece68d198f005a_f3c61f28-c4b6-44f0-8699-887a0291d6d2.jpg?v=1788913127","url":"https:\/\/voomisupply.com\/products\/guhring-9055190051100-cobalt-drill-bit-no-7-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
