Frequently Asked Questions

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

This CHICAGO-LATROBE 13/64" extra long drill bit is designed for deep-hole drilling in metal, wood, and plastics where standard-length bits cannot reach. Its 12" overall length and 118° notched point reduce walking and improve chip evacuation in industrial machining, maintenance, and fabrication applications.

What are the specifications of the CHICAGO-LATROBE 50726 drill bit?

The CHICAGO-LATROBE 50726 is a 13/64" diameter, 12" overall length extra long drill bit with a 118° notched point. It is made from black oxide high-speed steel (HSS) for heat resistance and reduced friction. The bit diameter measures 0.2031 inches.

Where to buy CHICAGO-LATROBE extra long drill bits worldwide?

3G Electric supplies CHICAGO-LATROBE extra long drill bits worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on the 50726 or other extended-length HSS drill bits.

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

Choose a bit length that exceeds your hole depth by at least 1 inch. For metal, use black oxide HSS like this CHICAGO-LATROBE 50726 for heat dissipation. Match the point angle (118°) to the material hardness. Ensure the shank fits your chuck and the flute design clears chips effectively.
