Chicago-latrobe 47349 Jobber Drill Bit 13 Mm Hss

Product Description

The CHICAGO-LATROBE 47349 is a jobber length drill bit designed for general-purpose drilling in ferrous and cast iron workpieces. It is manufactured from high speed steel with an oxide coating that helps reduce friction and extend service life under normal shop conditions. The bit measures 13 mm (0.5118 inches) in diameter with a 118-degree standard point angle and a two-flute regular spiral configuration. Overall length is 151 mm (5.94 inches), with a flute length of 101 mm (3.98 inches) and a straight-cylindrical shank. The web-thinned, tapered web design reduces cutting resistance at the point. This bit is suited for machinists, fabricators, maintenance technicians, and trade professionals working with drill presses, lathes, or handheld power tools.

This drill bit is built for general-purpose production and maintenance drilling in cast iron and steel. The straight-cylindrical shank fits standard three-jaw chucks without modification, making it compatible with common corded and cordless drill drivers as well as drill press spindles. The oxide finish and web-thinning make it a practical choice for repetitive hole-making tasks in fabrication shops, mechanical rooms, and field service environments. It ships as a single bit (package quantity of 1).
