Frequently Asked Questions

What is the CHICAGO-LATROBE Jobber Length Drill Bit #23 used for?

This drill bit is designed for aerospace and precision manufacturing applications requiring NAS 907 Type B compliance. Its 135° split point reduces walking and drilling force, making it suitable for high-strength alloys and sheet metal. The black oxide HSS construction provides wear resistance and chip evacuation.

What are the specifications of the CHICAGO-LATROBE 45693 drill bit?

The CHICAGO-LATROBE 45693 is a #23 jobber length drill bit with a 0.1540 inch diameter, 135° split point, and black oxide high-speed steel construction. It meets NAS 907 Type B aerospace specifications. The split point geometry reduces thrust and prevents walking on curved surfaces.
