Our M42 Cobalt drill bits are manufactured here in the USA and are of the highest
quality. Don’t be fooled by our low drill prices. Due to our purchase volumes and
low overhead, Aircraft Specialty has Incredibly Low Prices on Cobalt Drill Bits.
These are a poor business decision for us as they last much longer than a High Speed
Steel Drill bit. You won’t need to purchase as many replacements. But with all
the money you save on replacement bits, we hope you are able to take advantage of
some of our custom Aircraft Parts.
