Review on 🔩 Split Heavy Cobalt Drill America by Jerry Estrada

I confess that I bought them specifically to use them under high downtime conditions. That's why the shorter length was so attractive. Using a hand drill, drill out the large aluminum rivets that held the steel and aluminum panels together. I was fully prepared to break the bits and chip the cutting edges. Guess I did all the work on the first shot. Will you be just as lucky? I do not know. Maybe my experience with metal saved the beats? However, I was so impressed that I bought other sizes to have these works on hand. If you have experience drilling metal and know well when to see it and hold it in your hands, buy these and try them. Then write your own review based on your experience. They don't tear, but they might exceed your expectations for the price.
