It features a 135-degree split point that reduces walking on entry and lowers thrust requirements, making it well suited for production and maintenance drilling. The bronze oxide coating provides mild lubricity and heat resistance during cuts. With a parabolic flute geometry, chips evacuate efficiently even in deeper holes, reducing the need for peck drilling in many applications. This is a right-hand cutting, two-flute design built to DIN and NAS specification standards and classified as a heavy-duty grade bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for cutting steel, cast iron, aluminum, and other non-ferrous materials. It is commonly used in metal fabrication shops, maintenance and repair operations, and general machining environments where a reliable, mid-size jobber drill is needed. The straight cylindrical shank fits standard three-jaw drill chucks found on drill presses, CNC machining centers, and hand-held power drills. The 5xD flute-to-diameter ratio and h8 shank diameter tolerance make it appropriate for applications that demand consistent hole sizing and repeatability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction with bronze oxide coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and minimizes bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, two-flute design with web-thinned point\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with h8 tolerance for consistent chuck fit\u003c\/li\u003e\n  \u003cli\u003eMeets DIN and NAS specification designations; heavy-duty grade classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard three-jaw chucks accepting a 9.1 mm straight shank.

Ensure the shank is fully seated and the chuck is tightened before operation. Use cutting fluid or coolant appropriate for the workpiece material to extend tool life, particularly when drilling steel. Inspect the cutting edges and point for wear or chipping before each use and replace the bit if edge integrity is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.10 mm (0.3583 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 125.00 mm (4.9213 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 81.00 mm (3.1890 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.1 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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\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\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\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: 9010180091000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51743273976114,"sku":"9010180091000","price":42.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3da85e8fffd1637c8c8646e6fe5f7276_982e72ff-32f2-406d-85cc-2397340bf776.jpg?v=1788844888","url":"https:\/\/voomisupply.com\/products\/guhring-9010180091000-cobalt-jobber-drill-9-10mm","provider":"Voomi Supply","version":"1.0","type":"link"}
