It features a 130-degree split-point tip with web thinning to reduce thrust and improve centering on entry. The parabolic flute geometry accelerates chip evacuation, making this bit well-suited for deeper holes where chip packing is a concern. The bright, uncoated finish and tapered web configuration are consistent with DIN 338 specifications for heavy-duty drilling applications. Machinists and maintenance technicians are the primary users of this series.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in steel, cast iron, aluminum, and other non-ferrous materials. The Series 549 parabolic flute design supports drilling depths up to approximately 1.902 inches in a single pass before chip clearing is required. With an overall length of 3.6563 inches and a flute length of 2.25 inches, it fits standard drill chucks and CNC tool holders that accept a 0.2280-inch straight cylindrical shank. It is appropriate for both manual and machine drilling on production floors, job sites, and maintenance shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 1 wire size, 0.2280 inches diameter with a straight cylindrical shank of matching diameter\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle with web thinning for reduced entry thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry for efficient chip evacuation at a 5xD flute-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eBright uncoated high-speed steel construction rated for steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration for consistent rigidity along the flute length\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 specification for jobber-length drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338 jobber-length replacement for No. 1 wire gauge drill applications in standard drill chucks and CNC tool holders that accept a 0.2280-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit should be performed by a qualified machinist or maintenance technician familiar with drill press or CNC spindle setup. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the material being drilled. Reduce feed rate when drilling cast iron or hardened steel to extend tool life. Do not exceed the recommended maximum drilling depth of 1.902 inches 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 Size (Wire)\u003c\/strong\u003e: No. 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2280 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: 3.6563 inches (92.87 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.902 inches (48.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered with Web Thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9005490057900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51746466234674,"sku":"9005490057900","price":30.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9307ac256bb01c2a0ffcb17f957cc233.jpg?v=1788870556","url":"https:\/\/voomisupply.com\/products\/guhring-9005490057900-jobber-drill-0-2280-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
