In addition to these two factors, we also consider the following:
1- Price
Don’t purchase the highest quality Cobalt Drill Bits if you don’t compare prices.

Getting a warranty on your product is the last thing you should do. How did this come about? I don’t know what you would do if something went wrong with them or you wanted an exchange.
