Hi All, I just bought a used ¾ inch impact wrench at the swap meet for $30 dollars. I'm not familiar with the brand name, "Milwaukee Pneumatic tool", model number MP-151, made in Japan, does anyone know any thing about this brand? I currently own an Ingersoll Rand model 244 ½ impact and I was hoping that the Milwaukee Pneumatic has more power for the really big jobs. Is this a good wrench? Does any know if it is still being made possibly under a different brand name?
