Because grinders use rotary action rather than impact to remove material, the depth of material removal is limited to about 1/8 inch, depending on the type of attachment used. They generally leave behind a smoother profile than scarifying or shotblasting, and when working on hard, dense concrete they may polish rather than abrade the surface.
