Ground to a 135-degree split point with a parabolic flute geometry, this drill reduces walking at entry and promotes fast chip evacuation in deeper holes. A bronze oxide coating provides additional lubricity and heat resistance during cutting. With an overall length of 4.921 inches and a flute length of 3.189 inches, this two-flute bit fits standard drill chucks with a straight cylindrical shank. It is used by machinists, maintenance technicians, and fabricators who require consistent, repeatable results in production or field drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for right-hand cutting in steel, cast iron, aluminum, and other non-ferrous materials. Its parabolic flute profile makes it well-matched for applications where chip packing is a concern, particularly in deeper holes relative to diameter. The 5xD flute-to-diameter ratio supports drilling at elevated feed rates without the need for coolant-through capability. Typical install scenarios include fabrication shops, maintenance facilities, and field service operations where hard or abrasive base materials are encountered regularly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with bronze oxide coating for heat resistance and extended tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e135-degree split point geometry reduces entry walking and lowers thrust force required\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes aggressive chip evacuation in deeper holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned point reduces cutting resistance at the chisel edge\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with h8 diameter tolerance for consistent chuck fitment\u003c\/li\u003e\n\u003cli\u003eConforms to DIN and NAS specification designations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber drill for use in standard 3-jaw drill chucks and compatible with machines accepting a 9.2 mm straight shank; intended for drilling steel, cast iron, aluminum, and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trade technicians familiar with proper drilling speeds and feeds for cobalt tooling. Secure the shank fully in the chuck and verify runout before beginning a cut. Power down and de-energize the machine before changing tooling. Avoid using this bit in hammering or percussion modes, as cobalt tooling is not designed for impact drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.20 mm (0.3622 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 125.00 mm (4.921 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 81.00 mm (3.189 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 44 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\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\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: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bronze Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN, NAS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\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: 9010180092000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51740519104818,"sku":"9010180092000","price":42.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3da85e8fffd1637c8c8646e6fe5f7276_516ded40-86cb-4ec7-b2dd-ab937a609714.jpg?v=1788825617","url":"https:\/\/voomisupply.com\/products\/guhring-9010180092000-cobalt-jobber-drill-9-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
