Wow, what a great grinder. I needed a variable speed angle grinder for tile work. I already have a DeWalt but it didn't have variable speed and changing the blade or moving the guard was a pain. So I did a lot of research and came across the Metabo coffee grinder. Mateo is new to me, but has been for a long time. In addition to the variable speed, two main features convinced me. 1) tool-free blade change and 2) tool-free guard adjustment. I know it's expensive but it's worth it. And power.super good!
