I have been thinking of putting an air drill on my SB for drilling Aluminum extrusions. I had a though why use an air drill? It seems like an inefficient way to make power for a drill running my 5HP air compressor to run a drill, why not an electric drill?

I first thought of buying a hand drill and constructing a mount for it but I have looked at a bunch of different types of hand drills and can't find one that would be easy to make a mount for. What do you think about a motor like the one in this link and then mounting a chuck on it?

This would also be less money than an air drill.

I did not notice that motor was DC

Would this be too heavy piggy backed with my 3HP Columbo spindle?

Absolutely - without a doubt.

My recommendation would be to take a Milwaukee corded drill & remove the plastic grip & trigger assembly so that it is sort of an oblate vertical cylinder. Then you can cage mount it to your Colombo. You CAN'T kill one of these drills & they happen to be at the right RPM for drilling metal. With the right bits, you'll be drilling like butter...

Thanks after seeing that picture I did some research on the net and found a hammer drill that can be ran without hammering it is 2 speed 0-1500 & 0-3500 RPM that is a good range. It has the removeable handle near the chuck like the one in the picture which will be easy to make a mount for. The model I am looking at is a Milwaukee 5380-81. I would use my new mill but the rails are up to 8' long that need to be drilled. I will make a fixture for holding them to the table of the SB.
