It features a 135-degree split point that starts on contact and reduces walking without a center punch. The web-thinned, tapered web design lowers thrust and heat at the cutting edge. At 3-3\/4 inches overall length with a 2-1\/2 inch flute length, it fits standard drill chucks and drill presses used in metal fabrication, maintenance, and general holemaking work. The straight-cylindrical shank diameter measures 0.2055 inches, matching the 0.2055-inch decimal drill size. This is a heavy-duty grade bit built for production and job-site use by machinists, maintenance technicians, and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThe 66694043 is suited for holemaking in ferrous and non-ferrous metals, plastics, and composite materials in both shop and field environments. The TiN coating extends tool life compared to uncoated HSS by reducing friction and surface wear. The right-hand, regular-spiral flute geometry promotes efficient chip evacuation in through-hole and blind-hole applications. It is a single-bit package rated under NAS specification, making it appropriate for general-purpose production drilling where dimensional consistency is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 5 wire size, 0.2055 inches decimal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eTiN coating improves wear resistance over bare HSS\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web for reduced cutting force\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute promotes clean chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 3-jaw and keyless chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for any application requiring a No. 5 wire-size jobber-length drill bit with a straight-cylindrical shank conforming to NAS specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and maintenance technicians using a standard drill press, milling machine, or hand drill with an appropriate chuck capacity. Secure the shank fully in the chuck and verify runout before drilling. Use cutting fluid or appropriate lubricant when drilling ferrous metals to preserve coating life. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\u003c\/strong\u003e: TiN (Titanium Nitride)\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\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\u003eFlute Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\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: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned, Tapered\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\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\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: 66694043\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744213303602,"sku":"66694043","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f59644c9f43953d8e0c4126f0a70d12c.jpg?v=1788855064","url":"https:\/\/voomisupply.com\/products\/hertel-66694043-no-5-hss-tin-jobber-drill-bit-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
