3m Radial Bristle Disc 3/4" Diameter Brush Assortment 19 PCS Set 6 Different Grits and Mandrel by JTS Made in USA

I bought these for refinishing an old oak dresser with lots of grooves. I needed something narrow that could get into the grooves. First, I didn't realize how small they actually are. They are about the width of my thumb if that helps. My fault. Second, I also had no concept of how soft they actually are. I put three of these disks on my drill and it did nothing as far as sanding. Later, after sanding everything, with sand paper, I thought they might be good for at least finishing sanding, but all they seemed to do is polish the wood. So, my fault, hopefully this will help someone else. I'm sure these weren't meant to sand oak. I'm sure I will find another use for them.
