The present invention relates to a powered surgical tool that selectively provides rotational oscillations to a tool head (effector) to effect tissue modification during a surgical procedure. The present invention also relates to cutting tools and tissue modification tools that operate to modify tissue when rotated in either or both directions about the longitudinal axis of the tool. The present surgical tool and cutting tools are effective to modify selective tissues while selectively preventing the modification of other tissues. For example, hard tissue, like bone, may be modified while soft tissue is not modified, or soft tissue may be modified without modification to hard tissue.
