Frequently Asked Questions

What is the CHICAGO-LATROBE Jobber Length Drill Bit #12 used for?

This drill bit is designed for aerospace and precision industrial drilling applications. Its 135° split point reduces walking and eliminates the need for a center punch, while the TiN coating extends tool life in ferrous metals and high-temperature alloys.

What are the specifications of the CHICAGO-LATROBE 41682 drill bit?

The CHICAGO-LATROBE 41682 is a #12 jobber length drill bit with a 0.1890 inch diameter, 135° split point, and TiN-coated high-speed steel. It meets NAS 907 Type B standards for aerospace use. The manufacturer part number is 41682.

Where to buy CHICAGO-LATROBE drill bits worldwide?

3G Electric supplies CHICAGO-LATROBE drill bits worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us to source the 41682 or other NAS-spec tooling for your operations.

How to select the right CHICAGO-LATROBE drill bit for aerospace materials?

For aerospace alloys, choose a TiN-coated HSS bit like the CHICAGO-LATROBE 41682 with a 135° split point. This geometry reduces thrust and prevents wandering on curved surfaces. Match the diameter to your fastener or hole tolerance requirements per NAS standards.
