Frequently Asked Questions

What is the CHICAGO-LATROBE Aircraft Extension Drill #33 used for?

This drill is designed for aerospace and industrial applications requiring deep-hole drilling in tight spaces. Its 12-inch overall length and NAS 907 Type B compliance make it suitable for aircraft maintenance, sheet metal fabrication, and structural assembly where precision and reach are critical.

What are the specifications of the CHICAGO-LATROBE Aircraft Extension Drill #33?

The drill has a 0.1130-inch diameter (#33), 12-inch overall length, 135° split point, and black oxide HSS finish. It conforms to NAS 907 Type B and carries MPN 11157. The split point reduces walking and improves hole accuracy in hard materials.
