Built to DIN 1897 standards, this bit features a four-facet split point at 118 degrees that reduces walking on entry and lowers thrust requirements compared to a conventional point. The web-thinned, tapered-web construction improves chip evacuation and cutting efficiency. At 0.182 inches in diameter with a 2.284-inch overall length, it is a compact, rigid tool intended for use in drill presses, CNC machining centers, and screw machines where a shorter flute-to-length ratio increases stiffness and reduces deflection.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized to wire gauge No. 14 (0.182 inches decimal) and is suited for drilling aluminum as its primary workpiece material, though cobalt construction also handles harder alloys and work-hardening materials. The stub-length format is a standard choice for screw machine work, turret lathe operations, and any setup where tool overhang must be minimized to maintain hole accuracy. Licensed machinists, tool-and-die shops, and production drilling operations are the typical end users. The single-piece cobalt construction eliminates the delamination risk associated with coated HSS alternatives under high-heat cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFour-facet split point at 118 degrees reduces drill walking and entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCobalt construction maintains hardness and edge integrity at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eStub length (DIN 1897) provides increased rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n  \u003cli\u003e3xD flute-to-diameter ratio balances chip clearance with core strength for production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or standard production drill bit conforming to DIN 1897 for use in drill presses, CNC machining centers, turret lathes, and screw machines accepting a straight-cylindrical shank of approximately 0.182 inches diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Secure the shank fully in a drill chuck or collet and verify runout before beginning a production run, as even minor runout at this diameter will affect hole tolerance. Ensure the machine spindle is stopped and locked before changing tooling. Do not exceed the recommended maximum drilling depth of 0.672 inches per pass without retracting to clear chips, particularly when drilling aluminum at higher feed rates.\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. 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.182 inches (4.62 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.284 inches (58.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1819 inches (4.62 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.339 inches (34.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.672 inches (17.07 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5520\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 9055200046200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731969212722,"sku":"9055200046200","price":18.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/905a5006a23292a1fffffa23d3b1b98c_5e232280-93bf-4447-8c08-2006f9f43e66.jpg?v=1788737396","url":"https:\/\/voomisupply.com\/products\/guhring-9055200046200-cobalt-stub-drill-bit-no-14","provider":"Voomi Supply","version":"1.0","type":"link"}
