Frequently Asked Questions

What is the CHICAGO-LATROBE #23 jobber length drill bit used for?

This drill bit is designed for aerospace applications requiring NAS 907 Type B compliance. Its 135° split point reduces walking and thrust, while the TiAlN coating extends tool life in high-temperature alloys. It is suitable for drilling precision holes in materials such as stainless steel and titanium.

What are the specifications of the CHICAGO-LATROBE 42693 drill bit?

The CHICAGO-LATROBE 42693 is a #23 jobber length drill bit with a 0.1540-inch diameter, 135° split point, and TiAlN-coated high-speed steel construction. It meets NAS 907 Type B standards for aerospace drilling. The split point geometry enables self-centering and reduces burr formation.

Where to buy CHICAGO-LATROBE drill bits worldwide?
