Delphi Tip: Getting the Most from Your Grinder Bits Grinder Bits can be expensive, so make sure that you're utilizing all of the diamond coating. When you first install your bit, line it up so the bottom of the grit lines up with the top of the grinder work surface. When the exposed diamond coating is no longer effective, loosen the set screw and drop the bit down so the used portion is under the work surface exposing fresh grit that's ready to be used.
