Chicago-latrobe 44279 Jobber Drill Bit No. 9 Hss 118 Deg

Product Description

The CHICAGO-LATROBE 44279 is a jobber length drill bit in wire gauge size No. 9, equivalent to 0.1960 inches in decimal diameter. It is manufactured from high speed steel with a bright uncoated finish and features a standard 118-degree split point with web thinning for improved centering on entry. The overall length is 3-5/8 inches, with a 2-7/16-inch flute length and a straight cylindrical shank. This is a general-purpose drill designed for drilling non-ferrous metals and similar materials. It is sold as a single bit and is part of the Series 150D product line. Licensed tradespeople and machining professionals are the primary users of this tool.

The 44279 is suited for general-purpose drilling applications in light fabrication, maintenance, and repair work. Its jobber length format makes it compatible with standard drill chucks and drill presses used in shop and field environments. The bit is designed primarily for non-ferrous metal workpieces such as aluminum, brass, and copper, and its regular spiral flute geometry supports efficient chip evacuation in these materials. It conforms to DIN 338 standards, making it consistent with international tooling specifications used across trade and industrial settings.
