Frequently Asked Questions
What is the CHICAGO-LATROBE Jobber Length Drill Bit #12 used for?
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 ideal for CNC and manual drilling in aircraft maintenance and production.
What are the specifications of the CHICAGO-LATROBE 44982 drill bit?
The CHICAGO-LATROBE 44982 is a #12 jobber length drill bit with a 0.1890-inch diameter, 135° split point, and TiAlN-coated cobalt construction. It meets NAS 907 Type J specifications for aerospace use. The coating extends tool life in abrasive materials, and the split point enables self-centering without a center punch.
