Built from high speed steel with a steam oxide coating, it features a 135-degree split point that reduces walking and improves bite on curved or hard surfaces. The two-flute spiral design with a tapered web and web-thinned tip promotes efficient chip evacuation. With a 2 inch overall length and a straight cylindrical shank, this bit fits standard drill chucks and is sized for use in both hand-held and bench-mounted drilling equipment. It is a heavy-duty grade bit suited for production and maintenance drilling work.\u003c\/p\u003e\u003cp\u003eThis bit is rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its 5\/64 inch diameter and 1 inch flute length make it well suited for small-diameter through-holes and precise location drilling in fabrication, maintenance, and repair applications. The R10B series designation places it within a standard jobber length family commonly used in machine shops, tool rooms, and field service work. The NAS 907 and ANSI standards compliance confirms dimensional and performance consistency across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces drill walking and improves penetration on hard surfaces\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating provides mild lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web improves chip flow and reduces thrust requirements\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 and ANSI standards for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber length drill bit for use in standard 3-jaw drill chucks accepting a 5\/64 inch straight shank.
