like said before , most any of the sets will work for our stuff. Its nice to get the tap and drill set together, makes things easier. Sears sells some very good sets. thats what I bought when I was working in a machine shop.

If you taping aluminum or any metal, be sure to use tap oil. Your taps will last longer and you will cut a better thread. Aluminum seems to be the worse for loading up tooling, I would use a good amount of oil with taping it.

When taping its a good idea to back the tap out of the metal once in awhile and clean the tap. Taps can and will break at the worst time, I know I have broke more than my share.
