Frequently Asked Questions

What is the CHICAGO-LATROBE Extra Long Drill Bit 50523 used for?

This drill bit is designed for drilling deep holes in metal, wood, and plastic where standard-length bits cannot reach. Its 12-inch overall length and 118° notched point provide precise entry and reduced walking on curved surfaces, making it suitable for maintenance, fabrication, and industrial applications.

What are the specifications of the CHICAGO-LATROBE 50523 drill bit?

The CHICAGO-LATROBE 50523 is a 23/64-inch (0.3594-inch) extra-long drill bit with a 12-inch overall length. It features a 118° notched point and is made from black oxide high-speed steel (HSS) for increased wear resistance and heat dissipation during extended drilling operations.

Where to buy CHICAGO-LATROBE drill bits worldwide?

3G Electric supplies CHICAGO-LATROBE drill bits worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the 50523 model.

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

Choose a bit with a 118° point angle for general-purpose drilling in steel and alloys. The black oxide finish on CHICAGO-LATROBE HSS bits reduces friction and improves chip flow. Ensure the overall length exceeds the hole depth by at least 1 inch for proper clearance and coolant access.
