Frequently Asked Questions

What is the CHICAGO-LATROBE Jobber Length Drill Bit #25 used for?

This TiAlN-coated HSS drill bit is designed for aerospace applications requiring NAS 907 Type B compliance. Its 135° split point reduces thrust and walking, making it suitable for precision hole drilling in high-strength alloys and stainless steels.

What are the specifications of the CHICAGO-LATROBE 42695 drill bit?

The CHICAGO-LATROBE 42695 is a #25 jobber length drill bit with a 0.1495 inch diameter, 135° split point, and TiAlN-coated high-speed steel construction. It meets NAS 907 Type B standards for aerospace drilling applications.

Where to buy CHICAGO-LATROBE drill bits worldwide?

3G Electric supplies CHICAGO-LATROBE drill bits worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source and deliver genuine NAS-spec tooling like the 42695 to aerospace facilities across all regions.

How to select the right jobber length drill bit for aerospace materials?

For aerospace alloys, choose a TiAlN-coated HSS bit with a 135° split point like the CHICAGO-LATROBE 42695. The coating reduces heat and wear, while the split point eliminates center punching. Match diameter to hole tolerance and ensure NAS 907 compliance for critical applications.
