Built to DIN 1897 standards, it features a 5\/32 inch (0.1562 inch) diameter with a two-flute spiral configuration and a four facet, split point tip ground to 118 degrees. The web-thinned, tapered-web construction reduces thrust load and improves centering accuracy on entry. At 55.00 mm overall length with a 22.00 mm flute length, this is a compact, rigid bit suited to close-quarters work and machine setups where a jobber-length bit would flex or chatter.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited to production drilling, maintenance, and repair operations on aluminum and similar non-ferrous workpiece materials, though cobalt construction also provides the heat resistance needed when working harder materials. The straight-cylindrical shank with a 3.97 mm diameter seats securely in standard drill chucks, CNC turrets, and screw machine spindles. It is a single-unit replacement buy, packaged individually, and conforms to Series 5520 geometry for consistent results across repeat setups. Machinists, tool-and-die techs, and industrial maintenance professionals are the primary users of this bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for elevated heat resistance compared to standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003eFour facet split point at 118 degrees for fast penetration and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces axial thrust and chip packing\u003c\/li\u003e\n  \u003cli\u003eStub length (DIN 1897) provides added rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and machine spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement stub-length drill bit conforming to DIN 1897 and Series 5520 geometry; fits any drill chuck or machine spindle accepting a straight-cylindrical 3.97 mm shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using standard drill chuck keys or toolless quick-change systems as applicable to the machine. Ensure the spindle is fully de-energized and locked out before changing tooling. Secure the shank fully in the chuck to the maximum grip depth to prevent runout and shank pull-out under load. Do not use this bit beyond its maximum drilling depth of 0.6320 inch (16.05 mm) per 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 Size (Fractional)\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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 Helix\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: 55.00 mm (approx. 2.165 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22.00 mm (approx. 0.866 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.97 mm (approx. 0.1563 inches)\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: 0.6320 inches (16.05 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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.009 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: 9055200039700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753080717618,"sku":"9055200039700","price":17.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/905a5006a23292a1fffffa23d3b1b98c_e80c042a-9cda-43cf-9005-f82b9e9f4ff8.jpg?v=1788932622","url":"https:\/\/voomisupply.com\/products\/guhring-9055200039700-cobalt-stub-drill-bit-5-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
