Frequently Asked Questions

What is the CHICAGO-LATROBE 42623 drill bit used for?

The CHICAGO-LATROBE 42623 is a NAS 907 Type B jobber-length drill bit designed for aerospace drilling applications. Its 135° split point reduces walking, and the TiAlN coating extends tool life in high-temperature alloys. It is commonly used on CNC machines for precision hole-making in aircraft-grade materials.

What are the specifications of the CHICAGO-LATROBE 42623 drill bit?

The CHICAGO-LATROBE 42623 is a 23/64" (0.3594 inch) jobber-length drill bit with a 135° split point and TiAlN-coated high-speed steel. It meets NAS 907 Type B standards for aerospace use. The manufacturer part number is 42623, and it is designed for drilling in tough alloys.

Where to buy CHICAGO-LATROBE 42623 drill bits worldwide?

You can source CHICAGO-LATROBE 42623 drill bits worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine CHICAGO-LATROBE tooling for aerospace applications.

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

For aerospace drilling, select a bit that meets NAS 907 Type B specs, like the CHICAGO-LATROBE 42623. The 135° split point prevents wandering on curved surfaces, and TiAlN coating handles high heat. Match the diameter (23/64") to your hole tolerance and use proper speeds/feeds for titanium or stainless steel.
