Built from high-speed steel with a bright, uncoated finish, this bit is designed for clean, accurate drilling in non-ferrous and ferrous materials including aluminum. The 130-degree split point and parabolic flute geometry support faster chip evacuation and reduced thrust in production and maintenance drilling environments. Overall length is 1-5\/16 inches with a flute length of 15\/32 inches. This is a Series 549 tool manufactured to DIN 338 standards, suitable for machinists, tool-and-die professionals, and precision fabricators who need consistent performance in small-diameter work.\u003c\/p\u003e\u003cp\u003eThis bit is suited for light-duty precision drilling in aluminum, plastics, and mild steel where small-diameter accuracy is critical. The parabolic flute design makes it particularly effective in applications requiring efficient chip removal without pecking cycles. The straight-cylindrical shank fits standard keyless and keyed chucks across drill presses, CNC machining centers, and handheld power tools. Maximum drilling depth is 0.411 inches (10.44 mm), making it appropriate for shallow, precise through-holes or blind bores in thin stock and components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 59 diameter: 0.0409 inches for tight-tolerance small-diameter drilling\u003c\/li\u003e\n\u003cli\u003e130-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast chip evacuation and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web construction lowers cutting resistance\u003c\/li\u003e\n\u003cli\u003eBright uncoated high-speed steel finish suits aluminum and non-ferrous primary applications\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 338 standard for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber-length drill bit suitable for use in standard drill chucks accepting straight-cylindrical shanks across drill presses, CNC machining centers, and handheld power tools handling small-diameter wire-gauge bits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by machinists or qualified trade professionals familiar with small-diameter tooling. Secure the straight-cylindrical shank firmly in a properly sized chuck before operation to prevent slippage or runout. Use appropriate cutting fluid or coolant when drilling ferrous materials to extend tool life, even though this bit does not include through-coolant capability. Inspect the cutting edges before each use, as small-diameter bits are susceptible to breakage if run at incorrect feed rates or speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 59\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0409 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-5\/16 inches (33.34 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.411 inches (10.44 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0409 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 22.00 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: 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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.014 to 0.000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\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: 9005490010400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":67911536640306,"sku":"9005490010400","price":108.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91b625b6be763d6457790d9f3476601d.jpg?v=1791211822","url":"https:\/\/voomisupply.com\/products\/guhring-9005490010400-jobber-drill-bit-wire-59-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
