| I previously had a portable (on 2 wheels) Kobalt 30 gallon 1.5~HP compressor. I picked this thing up on sale at Tractor Supply for 899 and its a 2-stage rated at 175psi/~16CFM @ 90PSI. I have used the die grinder with it several times so far and I cannot believe how I lived with that small compressor for so long. I also broke the 1/2 impact out and the gun with that kind of air pressure almost seems invincible now!
