A vacuum vice for holding a bowling ball when drilling holes or engraving the ball includes inner and outer o-rings seals which form inner and outer concentric vacuum chambers that work together to form a seal with a bowling ball having surface imperfections or engraving. The inner vacuum chamber holds the ball against the inner seal and a vacuum passageway applies the vacuum to the outer vacuum chamber which seats the ball against the outer seal.
