Well this is my first hammer product as I am partial to Ebonite. Anyway I ordered a Acid Raw Hammer that I got a really good deal on. I ordered a 2-3 inch pin and I got a 0-1 pin. Anyway I think I can still to a good control drilling which I wanted to do in the first place. My stats are above average revs, 15-16 mph, and a PAP of 5 1/4 over and a 1/2 up. Do you guys think a control drilling is possible and if not what would you suggest? Thanks in advance.
