Part of the Series 120X lineup, this bit measures 0.25 inches in diameter with a 10-inch overall length and a 7.5-inch spiral flute. The 118-degree notched point angle and web-thinned construction reduce entry force and improve chip evacuation, making it well suited for production and maintenance drilling in ferrous materials. A black oxide finish provides light corrosion resistance and reduces friction during operation.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling cast iron and steel in applications that require extended reach into deep cavities, stacked assemblies, or confined structural members. Typical install scenarios include mechanical contractors, pipefitters, ironworkers, and maintenance technicians working on structural steel, equipment frames, or cast iron components where standard-length tooling falls short. Right-hand cutting direction suits conventional drill press and handheld drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25-inch (Letter E) diameter with 10-inch overall length for long-reach access\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in cast iron and steel drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree notched point with web thinning for reduced thrust and cleaner entry\u003c\/li\u003e\n  \u003cli\u003eTapered web and 2-flute spiral design promote efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces friction and provides light corrosion protection\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 for use in standard 3-jaw drill chucks accepting a 0.25-inch straight-cylindrical shank.
