locate any by Craftsman. From reading some reviews there appears to be
some "junk" out there. I suppose 1/2" will be fine until I need
something larger. Any last second advise on this purchase?

I bought this one a few years back. Works very well.

Then, I bought this set so I could counter sink in tighter areas.
