It measures 5\/16 inch (0.3125 inches) in diameter with a 10-inch overall length and a 7.5-inch flute length, giving technicians and machinists the reach needed to access deep or obstructed bore locations. The bit features a 118-degree notched point with web thinning for easier entry and reduced thrust force. An oxide finish provides baseline lubricity and corrosion resistance during use. This is a general purpose bit suited to production and service environments alike.\u003c\/p\u003e\n\u003cp\u003eThe 50505 is intended for drilling cast iron and steel in applications requiring extended reach beyond the capability of jobber-length tooling. Typical install scenarios include drilling through structural members, deep housings, or assemblies where the drill must extend past a surrounding component before reaching the work surface. The straight-cylindrical shank accommodates standard drill chucks in handheld, drill press, and mill setups. It is sold as a single bit and is appropriate for use by machinists, maintenance technicians, pipefitters, HVAC installers, and electricians working in tight or deep-clearance situations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-inch overall length and 7.5-inch flute length for deep-reach drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree notched point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide finish for general purpose durability\u003c\/li\u003e\n  \u003cli\u003eTapered web with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, 2-flute design\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0010 inches for consistent fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel workpieces in long-reach applications.
