The bit measures 1.50 mm (0.0591 inches) in diameter with a 32.00 mm (1.26 inches) overall length and a 9.00 mm (0.35 inches) flute length. It features a 118-degree four-facet split point and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The cobalt construction provides heat resistance suitable for harder work materials. This bit is sold individually (Package Qty 1) and is subject to a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for screw machine and production drilling applications where a short, rigid stub-length bit is required. Its primary workpiece material rating is aluminum, and the right-hand spiral flute geometry handles general-purpose through-hole and blind-hole work. The straight-cylindrical shank seats directly in standard drill chucks and screw machine collets. Shops running high-volume small-diameter drilling operations will find the Series 5520 geometry consistent with DIN 1897 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for improved heat and wear resistance versus standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point with web thinning reduces thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eStub (screw machine) length body provides added rigidity in short-reach drilling setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip removal in aluminum and similar materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and screw machine collets without adapters\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1897 specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897-compliant stub-length drill bit for use in drill presses, screw machines, CNC machining centers, and hand-held drilling equipment accepting a 1.50 mm straight-cylindrical shank.

Ensure the machine spindle is fully de-energized and locked out before changing tooling. Seat the straight-cylindrical shank fully into the chuck or collet and tighten to the machine manufacturer's specified clamping procedure before engaging the spindle. Inspect the cutting edges and point geometry before use; discard any bit showing chipping, cracks, or visible deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.50 mm (0.0591 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 32.00 mm (1.26 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm (0.35 inches)\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\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\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: 1.50 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 Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 6.75 mm (0.2660 inches)\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 -0.014 mm\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\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: 0.002 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 9055200015000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728131064114,"sku":"9055200015000","price":99.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/905a5006a23292a1fffffa23d3b1b98c_5a0a8d6c-1268-4dc0-98f7-d01b4c461917.jpg?v=1788688503","url":"https:\/\/voomisupply.com\/products\/guhring-9055200015000-cobalt-stub-drill-bit-0-0591-in","provider":"Voomi Supply","version":"1.0","type":"link"}
