It features a 135-degree split point that reduces walking on contact and allows drilling to start without a center punch in most applications. The oxide coating provides modest lubricity and corrosion resistance during use. At 5-5\/8 inches overall length with a 4-3\/16-inch flute length, this bit fits standard drill chucks and magnetic drill press setups commonly used by trade professionals across mechanical, plumbing, and electrical work.\u003c\/p\u003e\u003cp\u003eThis jobber drill is suited for production and maintenance drilling tasks in residential and commercial settings. The straight cylindrical shank accepts standard three-jaw chucks on hand drills, drill presses, and mill spindles. The 2-flute spiral configuration with a regular spiral type provides efficient chip evacuation in through-hole applications. Web thinning and a tapered web configuration reduce thrust requirements, making it practical for hand-held drilling in tight spaces common in mechanical and electrical rough-in work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces bit walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for heavy-duty drilling applications\u003c\/li\u003e\n\u003cli\u003eOxide finish provides surface lubricity and basic corrosion protection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drill thrust and heat buildup\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2 regular spiral flutes for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eNAS specification designation for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit for use in any straight-shank drill chuck; fits hand drills, drill presses, and milling machines accepting a 29\/64-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist, electrician, plumber, or mechanical technician can install and operate this drill bit using standard shop or field procedures. Secure the shank fully in the chuck and verify tightness before operation. Power down the drill completely before changing bits. Do not exceed the rated speed range for the material being drilled, and use cutting fluid when drilling steel to extend bit life and reduce heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 29\/64 inches (0.4531 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 29\/64 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\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 1.07 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: 84579309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728479453490,"sku":"84579309","price":22.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20fc8651dcc09e6178a77839ff96b4bf.jpg?v=1788691877","url":"https:\/\/voomisupply.com\/products\/hertel-84579309-jobber-drill-bit-29-64-in-hss-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
