The bit features a 135-degree split point that reduces walking on entry and lowers thrust force compared to a standard 118-degree grind. A TiAlN (titanium aluminum nitride) coating increases surface hardness and heat resistance, extending tool life in high-speed or dry-cutting applications. The straight-cylindrical shank seats in standard drill chucks without an adapter. At 3.75 inches overall length with a 2.5-inch flute, this is a general-purpose jobber geometry suited for production and maintenance work alike.\u003c\/p\u003e\n\u003cp\u003eThis bit is appropriate for metal fabrication, mechanical contracting, HVAC equipment work, and general industrial holemaking where a wire-gauge drill size is specified. The cobalt substrate and TiAlN coating make it well-suited for drilling stainless steel, hardened steel, cast iron, and other tough alloys that wear through standard HSS tooling quickly. It is sold individually and is used by machinists, millwrights, pipefitters, HVAC technicians, and maintenance professionals who need a reliable wire-gauge drill in a heavy-duty grade.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 6 wire gauge size — 0.2040 inches decimal diameter\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate for high heat and wear resistance in tough metals\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating adds surface hardness and extends tool life in dry or high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design improves chip evacuation and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute, regular helix — compatible with standard drill press and hand drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill replacement for any standard keyed or keyless drill chuck accepting a 0.2040-inch straight-cylindrical shank.

Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use appropriate cutting fluid or coolant when drilling stainless or hardened steel, unless process requires dry cutting where the TiAlN coating provides thermal protection. Follow applicable shop safety practices and personal protective equipment requirements for rotating cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eFlute Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.75 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: 0.2040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2000 to 0.2500 inches\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\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 4140000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749416468786,"sku":"4140000","price":20.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8033b1a903cf317def11d33cd323f3b.jpg?v=1788905825","url":"https:\/\/voomisupply.com\/products\/hertel-4140000-cobalt-jobber-drill-bit-no-6-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
