Built from high speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction during cutting. The 135-degree split point promotes self-centering on contact, reducing the need for a center punch and minimizing walking on hard surfaces. At 2.375 inches overall length with a 1.375-inch flute length, it fits standard drill chucks and is suited for production environments and general trade use. A web-thinned, tapered web configuration reduces thrust and improves chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is intended for holemaking applications in metal fabrication, maintenance and repair operations, and general industrial work. The straight-cylindrical shank with a 0.098-inch diameter seats directly in standard keyless or keyed drill chucks. Its regular spiral, two-flute design handles a range of materials including mild steel, aluminum, and plastics. Machinists, tool-and-die technicians, and maintenance professionals working in light to heavy-duty production settings will find this bit appropriate for repetitive drilling tasks where dimensional accuracy and consistent hole quality are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 40 (0.0980 inch decimal equivalent) for precision close-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drill pressure and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade high speed steel construction for demanding production use\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral, two-flute configuration for general holemaking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length drill bit for use in standard drill chucks accepting straight-cylindrical shanks in the 0.0500 to 0.1000 inch diameter range, conforming to NAS specification designation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a keyed or keyless drill chuck and verify the shank is fully seated and secured before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Match spindle speed to material type per standard machining references  -  excessive speed on hard materials will shorten tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit when hole quality degrades.\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: 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\u003eOverall Length\u003c\/strong\u003e: 2.375 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\u003eShank Diameter\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eDouble Margin\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\u003eSpecification Designation\u003c\/strong\u003e: NAS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 66694399\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743267094834,"sku":"66694399","price":55.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4075e646e3c1d53320233cf0040831e.jpg?v=1788844753","url":"https:\/\/voomisupply.com\/products\/hertel-66694399-jobber-drill-bit-wire-size-40-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
