Description
These diamond brushes are great at removing mill scale or surface impurities while minimizing material removal of what's underneath. These brushes should be used on the low speed of a variable speed grinder (see rpm chart for details).
Industrial grade diamond grit is electroplated onto knotted stainless steel wire strands.
Instead of being tightly knotted, the bristles on these brushes are left loose to flex and increase the contact area of the diamond grit with the surface being brushed.
