James1989 Posted April 13, 2022 Report Share Posted April 13, 2022 Hi everyone, I recently bought a used Milwaukee grinder (M18 cag115x). When it spins down I noticed there is a strange clicking and rattle noise. Is this normal or is it a broken bearing? Here is video I uploaded of the noise: Quote Link to comment Share on other sites More sharing options...

Biggie Posted April 20, 2022 Report Share Posted April 20, 2022 Its a little hard to tell from listening but I think what you're hearing is normal. The magnetic field and armature in the motor act almost like a brake so as it slows down they make a clicking noise as it jumps from one magnet to the next. Also if you put a disk on and just turn it by had you should get some resistance and then that same click. Quote Link to comment Share on other sites More sharing options...
