CHICAGO-LATROBE Jobber Length Drill Bit: #47, 135° Split Point, TiAlN-Coated Cobalt

This TiAlN-coated cobalt drill bit is designed for aerospace applications requiring NAS 907 Type J compliance. It drills precise holes in hardened steels, stainless steels, and high-temperature alloys. The 135° split point reduces walking and thrust, making it suitable for CNC and manual operations in aircraft manufacturing and maintenance.

The CHICAGO-LATROBE 45017 is a #47 jobber length drill bit with a 0.0785-inch diameter, 135° split point, and TiAlN-coated cobalt construction. It meets NAS 907 Type J standards for aerospace use. The coating extends tool life in abrasive materials, while the split point geometry enhances cutting efficiency and hole accuracy.

3G Electric supplies CHICAGO-LATROBE drill bits worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead times on the 45017 and other NAS-spec tooling. We source and deliver to meet aerospace procurement requirements.

For aerospace alloys, choose a cobalt drill bit with TiAlN coating and a 135° split point, like the CHICAGO-LATROBE NAS 907 Type J. The coating resists heat and wear, while the split point prevents wandering on curved surfaces. Match the diameter to your hole tolerance and use appropriate speeds and feeds for the material.
