An apparatus for truing out of round components of rotating mechanisms includes a grindstone and a weighted hand held holder for the grindstone. The holder includes a sleeve with a passageway for receiving the grindstone telescopically therein and for removal of debris created during the grinding process. The sleeve includes weights bonded thereto and a non-conductive shell encompassing the weights for protection of the user. The amount of weight added to the holder is predetermined and is coordinated to the cross-sectional area of the grindstone such that the apparatus has a predetermined amount of resistance to movement as the grindstone is used to remove high areas and imperfections from the surface of the out of round rotating component. The holder, when connected to a vacuum source, removes debris created by the grinding process by drawing the debris through the sleeve beneath the grindstone.
