Built to DIN 1897 standards, this Series 552 bit features a parabolic flute geometry and a web-thinned point that reduces thrust load and improves chip evacuation at the cutting edge. The 130-degree point angle suits the bit for fast, accurate entry into aluminum workpieces with minimal walking. Overall length is 3.74 inches with a flute length of 1.85 inches, keeping the tool rigid in short-reach applications. Right-hand cut, straight-cylindrical shank, and a bright uncoated finish round out the specification.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for screw machine, CNC, and manual drill press applications where a stub or screw-machine length tool provides the rigidity needed for accurate hole location. Typical use cases include production drilling of aluminum plate, block, and extrusion in both job-shop and high-volume machining environments. The parabolic flute profile handles chip clearing in deeper passes up to a maximum drilling depth of 1.189 inches. Machinists and toolroom technicians working to DIN specifications will find this bit a direct-fit for DIN 1897 tooling programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eStub screw-machine length provides increased rigidity compared to jobber-length drills\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes efficient chip evacuation in aluminum\u003c\/li\u003e\n\u003cli\u003e130-degree point angle optimized for aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration reduces drilling thrust and entry force\u003c\/li\u003e\n\u003cli\u003eBright uncoated high speed steel construction — no coating delamination risk on aluminum\u003c\/li\u003e\n\u003cli\u003eMeets DIN 1897 standard; diameter tolerance held to +0.000 to -0.027 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling for any machine spindle accepting a straight-cylindrical shank in the 0.4409-inch (11.20 mm) diameter range, conforming to DIN 1897 stub drill specifications.

Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the shank diameter before operation. Verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before beginning the cut. Do not exceed the maximum drilling depth of 1.189 inches 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 Diameter\u003c\/strong\u003e: 0.4409 inches (11.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.74 inches (95.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.8504 inches (47.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.189 inches (30.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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 Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\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: 9005520112000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732875510066,"sku":"9005520112000","price":68.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e27664d553ef898e1d29b9641583995.jpg?v=1788747812","url":"https:\/\/voomisupply.com\/products\/guhring-9005520112000-screw-machine-drill-bit-0-4409in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
