It measures 7\/64 inch (0.1094 inch decimal) in diameter with an overall length of 2-5\/8 inches and a flute length of 1-1\/2 inches. The 135-degree split point reduces walking at the start of a hole without requiring a center punch, and the TiAlN coating increases surface hardness and heat resistance for extended tool life in demanding drilling applications. This is a heavy-duty grade bit suited for professional shop and field use.\u003c\/p\u003e\n\u003cp\u003eThe 66692344 is a standard jobber-series drill bit used across metalworking, HVAC fabrication, mechanical contracting, and general maintenance trades. Its straight cylindrical shank fits standard three-jaw drill chucks. The 7\/64-inch size is a common choice for pilot holes, clearance holes for small fasteners, and sheet metal work. The right-hand spiral flute with regular helix efficiently clears chips during through-hole drilling. This bit carries the NAS specification designation, indicating it meets national aerospace standards for dimensional and performance consistency.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point starts on contact without center-punching and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat and wear resistance for extended run life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction lowers cutting resistance and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade high speed steel provides toughness for intermittent and interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard keyless and keyed drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets NAS specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard jobber-length drill bit compatible with any drill press, hand drill, or mill with a chuck capable of holding a 0.1094-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove drill bits only with the drill or press powered off and the chuck fully secured. Use appropriate cutting fluid or coolant when drilling ferrous metals to maximize coating life and prevent work hardening. Ensure the workpiece is clamped before drilling to prevent rotation. Inspect the cutting edges before each use and replace bits that show visible chipping or excessive wear to maintain hole quality and operator safety.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/64 inch (0.1094 inch)\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1094 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 66692344\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742988140850,"sku":"66692344","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e63c59da1be9f9d46f4fb2049990799.jpg?v=1788841272","url":"https:\/\/voomisupply.com\/products\/hertel-66692344-jobber-drill-bit-7-64-inch-hss-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
