Frequently Asked Questions

What is the CHICAGO-LATROBE Extra Long Drill Bit 50634 used for?

This extra-long drill bit is designed for deep-hole drilling in metal, wood, and plastic. Its 12-inch overall length and 118° notched point enable precise entry and chip evacuation in hard-to-reach areas, making it ideal for maintenance, fabrication, and production environments.

What are the specifications of the CHICAGO-LATROBE 50634 drill bit?

The CHICAGO-LATROBE 50634 is a 43/64-inch (0.6719-inch) extra-long drill bit with a 12-inch overall length. It features a 118° notched point and is made from black oxide-coated high-speed steel (HSS) for increased wear resistance and heat dissipation during extended use.

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

Choose a bit length that exceeds the hole depth by at least 1 inch for chip clearance. For metal, use a 118° point angle like the CHICAGO-LATROBE 50634. Match the bit diameter to your fastener or clearance requirement, and ensure your drill press or machine has sufficient torque and speed control.
