Built from high-speed steel with an oxide finish, it features a 135-degree split point that reduces walking on contact and requires less feed pressure than a standard 118-degree tip. The web-thinned construction further eases penetration in harder workpiece materials. At 3.5 inches overall length with a 2-inch flute, this is a compact mechanics-length bit suited for work in confined spaces or close-clearance applications. The straight cylindrical shank seats securely in standard drill chucks without special tooling.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized at 0.2340 inches (Letter A) and is intended for right-hand cutting in carbon steel, cast iron, high alloy steel, high tensile strength alloys, stainless steel, and general steel stock. It is a practical choice for maintenance mechanics, fabrication shops, and field service technicians who need a reliable mechanics-length bit for through-hole and clearance-hole drilling in production or repair environments. The spiral flute design provides efficient chip evacuation in these common workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers required feed pressure\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tip with parallel web configuration for easier penetration in hard materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance\u003c\/li\u003e\n  \u003cli\u003eMechanics length at 3.5 inches OAL keeps the bit maneuverable in tight spaces\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for efficient chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose mechanics-length drill bit compatible with any standard keyed or keyless drill chuck accepting a straight cylindrical shank.
