Frequently Asked Questions

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

This CHICAGO-LATROBE extra long drill bit is designed for deep-hole drilling in metal, wood, and plastic where standard-length bits cannot reach. The 10" overall length and 118° notched point provide precise entry and chip evacuation in industrial machining, maintenance, and fabrication applications.

What are the specifications of the CHICAGO-LATROBE 50500 drill bit?

The CHICAGO-LATROBE 50500 is a 19/64" (0.2969") diameter extra long drill bit with a 10" overall length. It features a black oxide finish on high-speed steel (HSS) and a 118° notched point for reduced walking and improved cutting action in ferrous and non-ferrous materials.

How to select the right extra long drill bit for deep hole drilling?

Select an extra long drill bit like the CHICAGO-LATROBE 50500 based on hole depth, material hardness, and required finish. For steel, choose black oxide HSS with a 118° point. Ensure overall length exceeds hole depth by at least 1" for chip clearance. Consult 3G Electric for application-specific recommendations.
