Review on 🔋 Metabo 18V Angle Grinder - 5.5Ah Battery Included by Kyle Awasthi

I bought a 6" cutoff first and after trying it out decided to buy it as 110V in some of the factories, where I work are hard to find. . I've been using this grinder for a few months with no problems, I don't do much grinding, mostly bar deburring or edge grinding. Suddenly it doesn't work. I turn it on and it accelerates to full speed and stops immediately with such force that if I try multiple times it loosens the lock nut holding the pad. I have tried unsuccessfully to contact Metabo.
