Chicago-latrobe 47515 3/8 in Jobber Drill Bit Hss Oxide

Product Description

The CHICAGO-LATROBE 47515 is a jobber-length twist drill bit designed for general-purpose drilling in metal fabrication and maintenance applications. Built from high speed steel with an oxide coating, this bit offers solid wear resistance for production and repair work. It features a 118-degree standard point angle, a right-hand spiral flute, and a web-thinned, tapered web configuration that reduces thrust at entry. The 3/8-inch diameter and 5-inch overall length fit standard drill chucks without adapters. Machinists, millwrights, pipefitters, and HVAC and plumbing professionals reach for this bit when drilling cast iron, mild steel, and similar ferrous materials.

The 47515 suits drilling tasks across residential and commercial job sites wherever ferrous metal work is required. Typical applications include drilling through steel plate, structural angle, pipe fittings, and equipment housings. The regular spiral flute evacuates chips cleanly in through-hole drilling. The tanged shank provides positive drive engagement in drill press chucks, as well as portable drill applications. Primary workpiece materials listed by the manufacturer are cast iron and steel.
