Frequently Asked Questions
What is the CHICAGO-LATROBE #48 jobber length drill bit used for?
This drill bit is designed for aerospace applications requiring NAS 907 Type B compliance. Its #48 wire-gauge size (0.0760 in) and 135° split point reduce walking and improve hole accuracy in high-strength alloys. The black oxide HSS construction provides wear resistance and lubricity for extended tool life in production drilling.
What are the specifications of the CHICAGO-LATROBE 45718 drill bit?
The CHICAGO-LATROBE 45718 is a #48 jobber length drill bit with a 0.0760 in diameter, 135° split point, and black oxide high-speed steel finish. It meets NAS 907 Type B standards for aerospace drilling. The split point geometry eliminates the need for center punching and reduces thrust requirements.
