Ground from high speed steel with a bright uncoated finish, it features a standard 118-degree split-point tip geometry and a regular spiral flute for efficient chip evacuation. The straight cylindrical shank measures 11\/64 inches in diameter and seats securely in standard drill chucks. Overall length is 3.25 inches with a flute length of 2.125 inches, giving it a 12xD depth-to-diameter ratio suitable for through-hole and blind drilling in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is a practical choice for HVAC fabrication, plumbing rough-in, electrical panel work, and general sheet metal or structural drilling tasks. The two-flute spiral configuration and web-thinned tapered web reduce entry force and help maintain hole straightness across a range of workpiece materials. It is sold individually but requires a minimum order of 12 units per the manufacturer's packaging structure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tapered web for reduced thrust and cleaner entry\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to flake or chip during high-temperature drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, two-flute design promotes consistent chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard 3-jaw keyed and keyless drill chucks\u003c\/li\u003e\n  \u003cli\u003eANSI-standard jobber length for compatibility with common drill press and hand drill setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit in the Series R10P-R15P-R18P for use in standard drill chucks accepting an 11\/64-inch straight cylindrical shank.
