Product Description

The CHICAGO-LATROBE Jobber Length Drill Bit (15/64", MPN 43615) is a TiCN-Coated HSS, NAS 907 Type B drill bit with a 135° split point. It is designed for aerospace applications, meeting NAS-Spec requirements for high-speed steel jobber-length drilling.

Frequently Asked Questions

What is the CHICAGO-LATROBE 43615 drill bit used for?

This CHICAGO-LATROBE Jobber Length Drill Bit is designed for aerospace applications requiring NAS 907 Type B compliance. Its 135° split point reduces walking and thrust, while the TiCN coating extends tool life in high-strength alloys. It is suitable for precision hole drilling in aircraft-grade materials.

What are the specifications of the CHICAGO-LATROBE 43615 drill bit?

The CHICAGO-LATROBE 43615 is a 15/64" (0.2344 inch) jobber length drill bit made from TiCN-coated high-speed steel. It features a 135° split point and meets NAS 907 Type B standards. This combination provides enhanced wear resistance and accurate hole positioning in demanding aerospace materials.

Where to buy CHICAGO-LATROBE 43615 drill bits worldwide?

3G Electric supplies the CHICAGO-LATROBE 43615 drill bit to customers worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location.
