The bit measures 15\/64 inches (0.2344 inches decimal) in diameter with a 3-7\/8 inches overall length and a 2-5\/8 inches flute length. The 135-degree split point reduces walking and decreases the force needed to start the hole without a center punch. An oxide coating provides corrosion resistance and reduces friction during cutting. This is a right-hand, two-flute design with a straight cylindrical shank and tapered web construction. Rated as heavy duty under the NAS specification designation, it suits demanding production and maintenance applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production shops, maintenance and repair operations, and field service work where consistent hole quality in the 0.2000 to 0.2500 inch size range is required. The straight cylindrical shank fits standard three-jaw drill chucks used in drill presses, hand drills, and CNC drilling operations. The regular spiral flute geometry clears chips efficiently in through-hole and moderate-depth drilling scenarios. Machinists, maintenance technicians, pipefitters, and general fabricators commonly stock this size for everyday holemaking tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/64 inch (0.2344 inch) diameter with 135-degree split point for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web construction lowers cutting resistance and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction maintains hardness at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces surface friction and provides light corrosion protection\u003c\/li\u003e\n\u003cli\u003e3-7\/8 inches overall length with 2-5\/8 inches flute length suits standard jobber drilling depths\u003c\/li\u003e\n\u003cli\u003eNAS specification designation confirms heavy duty grade compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit with a straight cylindrical shank; fits any three-jaw drill chuck accepting a 15\/64 inch straight shank across drill presses, cordless and corded hand drills, and CNC drill heads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified maintenance technician should verify chuck compatibility and shank seating before operation. Ensure the drill press or hand drill is powered down and the chuck is fully secured before beginning the drilling operation. Cutting fluid or coolant is recommended when drilling ferrous metals to extend tool life, though this bit does not support coolant-through delivery. Follow applicable workplace safety standards and wear appropriate eye and hand protection during use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/64 inches (0.2344 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-5\/8 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\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: 0.4 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84579168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728218980658,"sku":"84579168","price":46.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3af525bd48f78599c1dbe99848c7ff26.jpg?v=1788689752","url":"https:\/\/voomisupply.com\/products\/hertel-84579168-jobber-drill-15-64-in-135-deg-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
