Built from high-speed steel (HSS) with a bright, uncoated finish, this Series 552 bit measures 0.0469 inches (3\/64 inch) in diameter with an overall length of 1.1875 inches. The 130-degree point angle and parabolic flute geometry support fast chip evacuation and reduced thrust in softer materials. A web-thinned, parallel web configuration lowers entry resistance and improves hole accuracy. Licensed machinists, tool-and-die technicians, and production shop operators typically use this bit with screw machines, drill presses, and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis drill bit is optimized for use in aluminum and similarly machinable non-ferrous or soft materials. The stub-length (screw machine) body provides greater rigidity than jobber-length bits, reducing deflection in short-hole applications. With a maximum drilling depth of 0.245 inches and a flute-to-diameter ratio of 3xD, it suits shallow, precise bores common in high-volume production runs. The straight-cylindrical shank seats securely in standard drill chucks and collet holders without additional tooling adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/64 inch (0.0469 inch) diameter with a diameter tolerance of +0.000 to -0.014 mm per DIN 1897\u003c\/li\u003e\n\u003cli\u003e130-degree split point angle reduces walking and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile promotes efficient chip evacuation in aluminum and soft alloys\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web lowers drilling thrust and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eStub-length body at 1.1875 inches overall length maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight-cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use bit for screw machines, drill presses, and CNC machining centers requiring a 3\/64 inch straight-shank stub-length drill. Primary workpiece material is aluminum; the geometry is also suitable for other machinable soft metals and plastics where parabolic flute clearance is beneficial.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and changed by machinists or tool-room technicians following standard lockout\/tagout procedures before any chuck or collet work. Ensure the machine spindle is fully stopped and the chuck is tightened to the tool manufacturer's specified clamping range before operation. Do not exceed the maximum drilling depth of 0.245 inches per plunge without retracting to clear chips. Use of cutting fluid or coolant is not required but may extend tool life in sustained production use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fraction)\u003c\/strong\u003e: 3\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0469 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.1875 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.3125 inches (7.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.245 inches (6.22 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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\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\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9005520011900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748126228786,"sku":"9005520011900","price":100.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13d48a8f5e5ccaeea3fc5c775a3f5f47.jpg?v=1788889394","url":"https:\/\/voomisupply.com\/products\/guhring-9005520011900-screw-machine-drill-bit-3-64-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
