Review on Efficiently Grind with HOYIN Knotted Carbon 8 11UNC Grinder by Rob Madden

Revainrating 4 out of 5

As good as wheels for twice the price.

For cleaning expansion joints on a concrete road, removing old polyurethane caulk. The concrete hits all the wire wheels pretty hard so the 50% labor saving is worth it.

Pros
  • Abrasive Brushes
Cons
  • Slightly wrinkled
