I have a 4.5" grinder I bought at an auction for $5. It did NOT come with the tool to remove the disc off the head. I went to Home Depot at lunch and they don't carry them...........
Is there a way to remove the disk from the head using something other than the special tool? I can put a wrench on the head but need the 2 small hole thingy to turn the disc piece lose/off.............

Hate to admit it, but yes, I've been using one of those for years - originally bought it for the fork caps on my airhead BMWs, but since those are gone I use it on my Milwaukee grinder all the time.
