Frequently Asked Questions

What is the CHICAGO-LATROBE Extra Long Drill Bit 50624 used for?

This drill bit is designed for deep-hole drilling in metal, wood, and plastic. Its 12-inch overall length and 118° notched point allow access to recessed areas and reduce walking on curved surfaces. The black oxide HSS construction provides heat resistance and chip evacuation in industrial maintenance and fabrication applications.

What are the specifications of the CHICAGO-LATROBE 50624 drill bit?

The CHICAGO-LATROBE 50624 is a 41/64-inch (0.6406-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). This extended-length design is suited for drilling deep holes in tough materials.

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

For deep hole drilling, choose a bit with sufficient flute length to clear chips, like the CHICAGO-LATROBE 50624 with 12-inch overall length. Match the point angle (118° for general purpose) and coating (black oxide for reduced friction) to your material. Ensure the shank fits your chuck and the bit is rigid enough to prevent deflection.
