Frequently Asked Questions

What is the CHICAGO-LATROBE #40 jobber length drill bit used for?

This TiCN-coated HSS drill bit is designed for aerospace and precision machining applications. Its 135° split point reduces walking and thrust, while the NAS 907 Type B specification ensures compliance with stringent industry standards for drilling in high-strength alloys.

What are the specifications of the CHICAGO-LATROBE 43710 drill bit?

The CHICAGO-LATROBE 43710 is a #40 jobber length drill bit with a 0.0980 inch diameter, 135° split point, and TiCN-coated HSS construction. It meets NAS 907 Type B requirements, making it suitable for aerospace drilling tasks that demand precision and durability.

Where to buy CHICAGO-LATROBE drill bits worldwide?

3G Electric supplies CHICAGO-LATROBE drill bits worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner, we provide genuine NAS-spec tooling like the 43710 to aerospace and industrial buyers, ensuring compliance with your procurement requirements.

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

For aerospace applications, choose a drill bit that meets NAS 907 Type B standards, like the CHICAGO-LATROBE 43710. A 135° split point aids self-centering, and TiCN coating extends tool life in high-strength materials. Match the diameter (e.g., #40 at 0.0980 inch) to your hole size and material hardness.
