I've had my Metabo angle grinder for many years. It finally gave up the ghost. I'm trying to find a like replacement, but I don't know the model number of it. It uses a 4 1/2 or 5 inch spindle washer setup. When I turned it on a light would flash 3 times then it would run. It also had a governed speed. Lets say in a heavy grind or cut it would speed up , then go back to normal no load speed. I've been looking around , but haven't found a grinder like this one. people look at me like I grew a 3rd eye in the middle of my fore head when I try to explain it to them. It's not a variable speed. But it does speed up when under a load or slow down when load is off. Can't read the tag anymore. Thanks , Roy
