Frequently Asked Questions

What is the CHICAGO-LATROBE Aircraft Extension Drill used for?

This drill is designed for aerospace and industrial applications requiring deep-hole drilling in hard metals. Its 12" overall length and 135° split point reduce walking and improve chip evacuation, making it ideal for aircraft assembly and maintenance tasks where precision and reliability are critical.

What are the specifications of the CHICAGO-LATROBE 11108 drill?

The CHICAGO-LATROBE 11108 is a 1/4" diameter, 12" overall length aircraft extension drill with a 135° split point and black oxide HSS finish. It conforms to NAS 907 Type B and is manufactured under part number 11108. The black oxide coating provides lubricity and corrosion resistance for extended tool life.
