Frequently Asked Questions

What is the CHICAGO-LATROBE Extra Long Drill Bit 50580 used for?

This 33/64" extra long drill bit is designed for deep-hole drilling in metal, wood, and plastic. Its 118° notched point reduces walking on curved surfaces, while the black oxide HSS construction resists wear and heat. Common applications include maintenance, fabrication, and production environments requiring extended reach.

What are the specifications of the CHICAGO-LATROBE 50580 drill bit?

The CHICAGO-LATROBE 50580 is a 33/64" diameter extra long drill bit with a 10" overall length. It features a 118° notched point and is made from black oxide high-speed steel (HSS). The bit diameter measures 0.5156 inches. This extended-length design provides deeper drilling capacity than standard jobber bits.

How to select the right CHICAGO-LATROBE extra long drill bit?

Select based on hole depth, material, and required diameter. The 50580 with 10" overall length suits deep drilling where standard bits cannot reach. For harder materials, the black oxide HSS provides heat resistance. Ensure your drill chuck can accommodate the 33/64" shank. Always match speed and feed to the workpiece material for optimal performance.
