Drill America GLBCOX68 #8 x 6" Cobalt Aircraft Extension Drill Bit, GLBCO Series

Drill America Cobalt Aircraft Extension Drills are specifically designed for drilling through hard-to-reach areas with ease, thanks to their 135° split point tip that prevents walking and their round shanks that fit into a variety of tool holding systems.

These drills are effective in drilling tough materials like stainless steel, inconel, and titanium, making them perfect for aerospace applications.

With a thinner oxide surface treatment than black oxide, gold oxide identifies cobalt steel tools that perform similarly to uncoated tools.

The 6" overall length provides extra reach when needed, while the 118° standard point is effective on sizes smaller than 1/16".

Whether you're working on a small or large-scale project, Drill America Cobalt Aircraft Extension Drills are the perfect choice for any drilling task.
