Sized to wire gauge 40 (0.0980 inches decimal), it features a 135-degree split point that reduces walking and lowers the thrust required to start a hole without a center punch. A TiAlN coating increases surface hardness and heat resistance, extending tool life in ferrous materials and high-speed cutting conditions. The straight-cylindrical shank seats securely in standard keyless or keyed drill chucks. This bit is sized and built for machinists, millwrights, maintenance technicians, and tool-and-die professionals working in production or field environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is well suited for precision holemaking in steel, stainless steel, cast iron, and other hard or abrasive materials where standard high-speed steel bits wear prematurely. The jobber-length body balances reach and rigidity for general-purpose drilling in benchtop drill presses, CNC machining centers, hand drills, and mag-base drills. The right-hand spiral flute clears chips efficiently and works with standard right-hand spindle rotation. Web-thinned geometry reduces cutting resistance on entry, making it practical for both manual and powered equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge 40 sizing at 0.0980 inches decimal for precise hole diameter control\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides superior heat resistance over standard HSS for hard-material drilling\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases wear resistance and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web geometry lowers cutting force and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill replacement compatible with standard straight-shank drill chucks accepting a 0.0980-inch shank diameter, for use in drill presses, machining centers, mag-base drills, and hand-held power drills with right-hand spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstalled by machinists, maintenance technicians, and tool professionals using standard keyed or keyless drill chucks. Ensure the shank is fully seated and chuck jaws are tightened evenly before operation. Use appropriate cutting fluid or coolant for the workpiece material to maximize coating life, as this bit does not support through-coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace when point geometry degrades to avoid oversize or out-of-round holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0980 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eShank Diameter\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4140323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749306532146,"sku":"4140323","price":78.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b96dc91f65e6b2d126f67260f4705239.jpg?v=1788904322","url":"https:\/\/voomisupply.com\/products\/hertel-4140323-cobalt-jobber-drill-wire-40-0-0980-in","provider":"Voomi Supply","version":"1.0","type":"link"}
