A tool with a driver (32), a structure, a motor assembly (18) and a bumper (2102). The driver has a plurality of bumper tabs (632), each of the bumper tabs having an arcuate first contact surface that is formed about a tab axis (670), each tab axis being generally perpendicular to a translation axis about which the driver translates. The motor assembly is coupled to the structure and configured to selectively translate the driver along the translation axis. The bumper abuts the structure and includes a plurality of bumper members (2200). Each bumper member is located in-line with an associated one of the bumper tabs and includes an arcuate second contact surface that is formed about an axis that is generally orthogonal to the translation axis and the tab axis.
