A tool is provided for applying fasteners to a workpiece. The tool has a housing with a nosepiece, a motor, a drive actuator, a magazine assembly that holds fasteners, and a feed assembly with a feed actuator configured to move a lead fastener into the nosepiece. A driver in the housing is driven by a drive system that is associated with the driver actuator. A controller is connected to the feed actuator and the drive actuator to implement a firing sequence for driving each lead fastener into the workpiece using the driver and feeding the lead fastener into the nosepiece assembly. The actuators may be in the form of solenoids. The controller is designed to energize and deenergize the motor selectively while the drive actuator and feed actuator are activated.

Power tool

A powered driving tool, such as a nailer, having a magnetic filter in the contact trip that retains ferrous debris remaining in the nosepiece as a result of a first fastener being driven into a workpiece, and allows the ferrous debris to be expelled from the nosepiece with a portion of a second fastener, when the second fastener is driven into a workpiece.
