It measures 0.1772 inches (4.50 mm) in diameter with an overall length of 80 mm and a flute length of 47 mm. The bit carries a titanium nitride (TiN) coating to extend surface hardness and wear resistance. A four-facet split point at 118 degrees reduces thrust and self-centers on entry without a pilot hole. The straight-cylindrical shank seats securely in standard drill chucks. This bit is sized to wire gauge No. 16 and conforms to DIN 338 standards. Licensed HVAC technicians, machinists, and maintenance trades rely on this geometry for clean, accurate holes in a range of materials.\u003c\/p\u003e\n\u003cp\u003eThe 9055190045000 is suited for drilling aluminum, mild steel, stainless, and non-ferrous metals, consistent with material codes K, M, N, and P. The regular spiral flute with web-thinned, tapered web geometry evacuates chips efficiently in both through-hole and blind-hole operations. Maximum drilling depth is 40.25 mm (1.585 inches), making it appropriate for light structural components, brackets, panels, and sheet stock encountered in HVAC, plumbing, and electrical rough-in work. It is sold individually (quantity of one per package).\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction provides heat resistance for harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life between regrinds\u003c\/li\u003e\n  \u003cli\u003eFour-facet split point at 118 degrees self-centers and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting torque and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 5xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard three-jaw chucks and collets\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 specification for consistent sizing and tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338-compliant jobber-length replacement drill bit suitable for use in standard drill presses, hand drills, and CNC drilling operations requiring a No. 16 wire gauge (0.1772 inch) straight-shank bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight-cylindrical shank fully in the chuck before operation and verify runout is within acceptable limits. Machinists and maintenance technicians should use appropriate cutting fluid when drilling ferrous materials to protect the TiN coating and maintain dimensional accuracy. Inspect the cutting edges and point before each use; a chipped or worn split point will increase thrust and reduce hole quality. Follow applicable shop safety protocols and machine-guarding requirements during all drilling operations.\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. 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1772 inches (4.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 33 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 40.25 mm (1.585 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1772 inches (4.50 mm)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular (5xD ratio)\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Aluminum, non-ferrous metals, mild steel, stainless (Material Codes K, M, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 9055190045000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730434654514,"sku":"9055190045000","price":21.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc2796606b86affad3ece68d198f005a_cbb71b5b-0edb-4278-88fa-4f9f5df44411.jpg?v=1788717393","url":"https:\/\/voomisupply.com\/products\/guhring-9055190045000-cobalt-jobber-drill-bit-no-16","provider":"Voomi Supply","version":"1.0","type":"link"}
