Sized to No. 4 wire gauge (0.2090 inch diameter), it delivers efficient chip evacuation and fast penetration in demanding production drilling applications. The bright, uncoated finish is suited for use with cutting fluids where coating adhesion is not a priority. The two-flute parabolic geometry reduces thrust force and helps clear chips without clogging, making this bit effective in deep-hole work relative to diameter. It is manufactured to DIN 338 standards and carries a heavy-duty grade designation, indicating tighter tolerances and more consistent performance than general-purpose bits.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is intended for drilling steel, cast iron, aluminum, and other non-ferrous materials in production or maintenance environments. The 5xD flute-to-diameter ratio supports drilling depths up to 1.931 inches in a single pass without peck cycling in most setups. Typical users include machinists, maintenance mechanics, and industrial fabricators working on drill presses, CNC machining centers, or hand-held power tools requiring a straight cylindrical shank. The Series 549 designation places this bit within a well-established DIN-compliant product family from GUHRING.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 4 wire size, 0.2090 inch diameter with a tight tolerance of -0.018 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle for reduced thrust and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation in deep drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated high speed steel construction compatible with cutting-fluid use\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 standards, Series 549 heavy-duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338-compliant jobber drill for use in standard straight-shank drill chucks.

Power down and de-energize the machine spindle before changing bits. Apply cutting fluid appropriate to the workpiece material to extend tool life and maintain hole tolerance. Inspect the point for wear or chipping before each use; a dull or damaged point should be resharpened or the bit replaced to avoid oversized holes or workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2090 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\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.25 inches (57.15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.656 inches (92.87 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.931 inches (49.04 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2091 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.018 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Aluminum and Non-Ferrous\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: 9005490053100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732713668914,"sku":"9005490053100","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4d2bcf93c7d664c2fa1345969e3cd3e.jpg?v=1788745954","url":"https:\/\/voomisupply.com\/products\/guhring-9005490053100-jobber-drill-no-4-hss-130-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
