Wondering if this would work for 3M wheels? Thinking about putting a fine on one side and a medium on another. I always head grizzly was better than the box stores… but have no experience.

Price seems right… but appears to be another made in china…..

Bench grinder

3/8 bore is too small for scotchbrite wheels. You want 1/2" arbor.
I recommend one 3M on one side and a buffing wheel on the other. One slip and a part is toast. Yep. I hit the wheel on the opposite side. Buffing wheel won't damage a part and it helps balance the grinder. I used one 7A wheel for the whole build.

Thank you for the advice!!!
