5 Best Angle Grinders - June 2020 - BestReviews
Aug 13, 2014· The Fein MultiMaster FMM 350 Q Goes to 11. I have the FMM 250 Q, which I purchased back in 2005. As the name states, the FMM 250 is 250 watts. Fein has added 100 extra watts of power to the newly designed MultiMaster FMM 350 and it's easy to see. There are times I can't tell if it's more powerful or if there is just less vibration.
