It is constructed from high speed steel (HSS) with a titanium nitride (TiN) coating that extends tool life by reducing friction and heat buildup at the cutting edge. The 135-degree split point geometry allows the bit to self-center on contact, reducing the need for a center punch on most workpieces. With a web-thinned, tapered web configuration and regular spiral flute, it evacuates chips efficiently during through-hole and blind-hole drilling operations. This bit is sold individually and is suited for use in hand drills, drill presses, and CNC drilling setups.\u003c\/p\u003e\u003cp\u003eThis jobber drill bit is intended for holemaking applications across maintenance, repair, fabrication, and light manufacturing environments. The straight-cylindrical shank fits standard three-jaw chucks without modification. Its heavy-duty grade designation and NAS specification make it appropriate for professionals requiring consistent performance in repetitive drilling tasks. Typical users include machinists, pipefitters, electricians, HVAC technicians, and general maintenance tradespeople who need a reliable, single-use or limited-run drill bit at a standard jobber length.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13\/64 inch (0.2031 inch) diameter with straight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n\u003cli\u003e135-degree split point geometry for self-centering without a center punch\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust force and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design clears chips efficiently in both ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eNAS specification designation confirms dimensional and performance 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 compatible with any three-jaw drill chuck accepting a 13\/64 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by tradespeople and machinists using standard three-jaw chucks on hand drills, drill presses, or CNC equipment. Secure the shank fully in the chuck and verify concentricity before beginning a cut. Use appropriate cutting fluid for ferrous metals to manage heat, even though the TiN coating provides some dry-cutting capability. Inspect the cutting edges before each use and replace if chipping or dulling is evident.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13\/64 inches (0.2031 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 13\/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 (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eGrade\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\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 84579689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735255843122,"sku":"84579689","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/256bf9b71d294b2fbad7fb5b3a7547c2.jpg?v=1788771048","url":"https:\/\/voomisupply.com\/products\/hertel-84579689-jobber-drill-bit-13-64-in-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
