It is designed for holemaking in hard, abrasive, and high-strength materials where standard high-speed steel bits wear prematurely. The 135-degree split point reduces walking and requires less feed force at entry, making it well-suited to tight-tolerance drilling in metal fabrication and mechanical service work. With an overall length of 1.5 inches and a flute length of 0.625 inches, this bit is built for short, precise holes in confined applications. A cobalt oxide and gold coating adds surface hardness and heat resistance. Installation and use are performed by machinists, pipefitters, electricians, and HVAC technicians drilling pilot or clearance holes in metal components.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in light industrial and trade service applications where small-diameter, tight-tolerance holes are required in hardened steel, stainless, cast iron, or other difficult-to-machine metals. The straight-cylindrical shank fits standard drill chucks without adapters. The regular spiral and tapered web configuration provide consistent chip evacuation in short-hole drilling. It is appropriate for bench drills, hand drills, and drill presses used in mechanical, electrical, and plumbing rough-in or equipment repair work where wire-gauge-sized clearance holes are needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 64 (0.0360 inches) for precise small-diameter holemaking\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and entry force\u003c\/li\u003e\n  \u003cli\u003eCobalt construction handles high heat and hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003eOxide and gold coating increases surface hardness and extends tool life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web for improved chip flow and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute compatible with standard drill equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill replacement for applications requiring a wire gauge 64 straight-shank drill bit with a 0.0360-inch diameter.

Secure the straight shank firmly in a properly sized chuck before operation. Power down all equipment and follow lockout\/tagout procedures when drilling into energized or pressurized systems. Use appropriate cutting fluid for extended tool life when drilling hard metals, and avoid excessive feed pressure that can deflect or break small-diameter bits.\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: 64\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0360 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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Gold (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 04139119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732556513586,"sku":"04139119","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c69ff3837337edf26de45957b73c2601.jpg?v=1788744419","url":"https:\/\/voomisupply.com\/products\/hertel-04139119-cobalt-jobber-drill-bit-wire-64-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
