Designed for heavy-duty drilling applications, it features a 135-degree split point for fast, self-centering starts with minimal walking. The two-flute spiral configuration with a web-thinned, tapered web design reduces thrust and improves chip evacuation. At 2-3\/8 inches overall length with a 1-3\/8 inch flute length, this bit fits standard drill chucks via its straight-cylindrical shank. It meets NAS 907 Type J standards and is suited for use by machinists, maintenance technicians, and trade professionals requiring consistent small-diameter drilling performance.\u003c\/p\u003e\n\u003cp\u003eThe C70172 is optimized for drilling aluminum as its primary workpiece material, though M42 cobalt construction provides the heat resistance and edge retention needed across a range of ferrous and non-ferrous materials. Typical applications include production drilling, maintenance and repair operations, and fabrication tasks where wire-gauge precision is required. The 0.0995-inch shank diameter matches the cutting diameter, making this a true jobber-length format suitable for portable drills, drill presses, and CNC equipment with compatible chucks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt material grade provides superior heat resistance and extended tool life compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003e135-degree split point enables self-centering starts and reduces required thrust force\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating helps reduce friction and provides basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance and improves chip flow in deep holes\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J specification for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber length drill bit for applications requiring wire gauge size 39 (0.0995 inches) drilling, compatible with standard straight-chuck portable drills, drill presses, and CNC spindles within the 0.0500 to 0.1000 inch drill bit size range per Series 2213.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a clean, properly sized drill chuck and tighten securely before use. Power down and de-energize any machine tool before changing bits. Use appropriate cutting fluid or coolant when drilling ferrous materials to preserve edge life, noting this bit does not support coolant-through operation.
