The bit measures 0.1890 inches in diameter with a 3-3\/8 inch overall length and a 2-1\/16 inch flute length. The 130-degree split point reduces walking on entry and lowers thrust requirements on harder stock. A parabolic flute geometry improves chip evacuation and allows faster feed rates compared to standard spiral flutes. Web thinning at the tip further reduces cutting resistance. Licensed machinists, tool-and-die professionals, and maintenance technicians reach for this bit when drilling aluminum, non-ferrous metals, and plastics where chip packing is a concern.\u003c\/p\u003e\u003cp\u003eThe 9005490048000 is catalogued in GUHRING Series 549, a jobber-length parabolic flute line rated primarily for aluminum and non-ferrous workpiece materials (ISO material codes K, N, and P). The straight-cylindrical shank fits standard drill chucks without modification. Maximum drilling depth is 1.7640 inches, making it suitable for through-holes and blind-holes in typical sheet metal, plate, and extrusion work found in fabrication shops, HVAC equipment assembly, and general mechanical maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 338 specification jobber-length geometry: 3-3\/8 inch OAL with 2-1\/16 inch flute length\u003c\/li\u003e\n\u003cli\u003e130-degree standard point angle with web thinning for reduced entry thrust and less walking\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile promotes fast, clean chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no coating interference on close-tolerance holes\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with web-thinned tip for lower cutting forces\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; 2-flute design for maximum chip clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stocking drill for any application requiring a No. 12 wire-gauge (0.1890 inch) jobber-length bit with a straight-cylindrical shank meeting DIN 338 tolerances.

Secure the shank fully in the chuck to the depth recommended by the chuck manufacturer before drilling. Always power down and de-energize the machine before changing tooling. Follow applicable OSHA machine-guarding requirements and wear appropriate eye and hand protection when drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.7640 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1890 inches\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: 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Non-Ferrous (ISO K, N, P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.018 to 0.000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 549\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 9005490048000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753914270002,"sku":"9005490048000","price":22.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef1e5e985da66ae93b320b323c28aff1.jpg?v=1788942013","url":"https:\/\/voomisupply.com\/products\/guhring-9005490048000-no-12-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
