Frequently Asked Questions

What is the CHICAGO-LATROBE Jobber Length Drill Bit 44916 used for?

This TiAlN-coated cobalt drill bit is designed for aerospace and high-strength alloy drilling. Its 135° split point reduces thrust and walking, while the NAS 907 Type J spec ensures compliance with aerospace fastener-hole standards. It is ideal for stainless steel, titanium, and other tough materials.

What are the specifications of the CHICAGO-LATROBE 44916 drill bit?

The CHICAGO-LATROBE 44916 is a 1/4" (0.2500 inch) jobber-length drill bit with a 135° split point, TiAlN coating on cobalt steel, and meets NAS 907 Type J requirements. It is designed for precision drilling in aerospace-grade materials and offers extended tool life under high heat.

Where to buy CHICAGO-LATROBE 44916 drill bits worldwide?
