Built to DIN 1897 standards, this right-hand spiral flute bit features a 118-degree four-facet split point and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 5.00 mm (0.1969 inches) in diameter, matching the drill diameter for straightforward chuck mounting. At 62.00 mm (2.44 inches) overall length with a 26.00 mm (1.02 inch) flute length, the stub geometry increases rigidity and reduces deflection compared to jobber-length bits. Licensed machinists, toolmakers, and industrial maintenance technicians are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in CNC machining centers, drill presses, and hand-held power tools where a short, stiff cutting tool is required. The primary workpiece material designation is aluminum, though cobalt construction provides heat resistance for broader application in general-purpose production environments. With a maximum drilling depth of 0.728 inches (18.50 mm) and a 3xD flute-to-diameter ratio, it is well matched to shallow-hole, high-cycle drilling operations. Package quantity is one bit per unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material with coated finish for extended tool life and heat resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eStub (screw machine) length at 62.00 mm (2.44 inches) overall for maximum rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with tapered web configuration promotes efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for direct chuck mounting without adapters\u003c\/li\u003e\n  \u003cli\u003eBuilt to DIN 1897 specification with a diameter tolerance of +0.000 to -0.018 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production drill bit for Series 5520 stub-length applications conforming to DIN 1897, suitable for drill presses, CNC machining centers, and handheld power tools accepting a 5.00 mm straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Ensure the spindle or chuck is fully de-energized and at a complete stop before inserting or removing the bit. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet to prevent slippage under load. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.00 mm (0.1969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62.00 mm (2.44 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 26.00 mm (1.02 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.728 inches (18.50 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.00 mm (0.1969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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\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: 0.018 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: 9055200050000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51746364031282,"sku":"9055200050000","price":20.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/905a5006a23292a1fffffa23d3b1b98c_8044b1cc-bb52-444a-8a33-9521e243f8e5.jpg?v=1788869025","url":"https:\/\/voomisupply.com\/products\/guhring-9055200050000-cobalt-stub-drill-bit-0-1969-in","provider":"Voomi Supply","version":"1.0","type":"link"}
