Built from high speed steel with an oxide finish, this bit measures 0.3438 inches in diameter with a 10-inch overall length and a 7.5-inch flute length. The 118-degree notched point and web-thinned, tapered web construction reduce entry force and improve chip evacuation. Two right-hand spiral flutes clear material efficiently during cutting. Machinists, millwrights, pipefitters, and maintenance technicians working with cast iron and steel stock are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThe 50516 is suited for production and maintenance drilling in cast iron and steel where extended reach is required. Typical applications include deep-hole drilling in structural steel, pipe flanges, machinery frames, and fabricated assemblies. The straight-cylindrical shank seats directly in standard drill chucks without adapters, making it compatible with portable drills, drill presses, and magnetic base drill units commonly used in field and shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra length 10-inch OAL provides reach beyond standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles cast iron and steel at normal drilling speeds\u003c\/li\u003e\n  \u003cli\u003eOxide finish improves lubricity and provides basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree notched point with web thinning reduces thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eTapered web with regular spiral flutes promotes consistent chip removal\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0010 inches ensures accurate bore sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Use appropriate cutting fluid or lubricant when drilling steel to extend tool life and maintain bore quality. Verify workpiece is clamped securely before drilling to prevent bit walking or workpiece rotation.
