Chicago-latrobe 44317 No. 47 Hss Jobber Drill Bit

Product Description

The CHICAGO-LATROBE 44317 is a No. 47 wire gauge jobber length drill bit machined from high speed steel with a bright uncoated finish. At 0.0785 inches in diameter and 2 inches overall length, this bit is built for general-purpose drilling in non-ferrous metals and similar materials. It features a standard 118-degree point angle, a regular spiral flute with web-thinned tip geometry for improved chip evacuation and reduced thrust, and a straight-cylindrical shank for use in standard drill chucks. Machinists, maintenance technicians, and fabricators reach for this size when precision small-diameter holes are required.

The 44317 suits light-duty production and maintenance drilling in non-ferrous metal workpieces such as aluminum, brass, and copper. The 2-inch overall length and 1-inch flute length make it well suited for shallow-hole applications in bench drill presses, hand drills, and CNC machines equipped with a standard chuck. The straight-cylindrical shank fits common drill chuck sizes without adapters, making it a practical choice for shop and field use alike.

Compatibility

Designed as a general-purpose replacement or stock bit for applications requiring a No. 47 wire gauge jobber length drill; fits any standard drill chuck accepting a 0.0785-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with proper tooling practices. Secure the shank fully in the chuck and verify runout before drilling. Always power down and lock out the machine before changing bits. Use appropriate cutting fluid or lubrication when drilling metals to extend tool life and maintain hole tolerance.
