Disclosed are methods and devices utilizing magnetized components to assist operation of an internal mechanism of a tool. Magnetic fields can assist a power tool comprising internal mechanisms that cycle very quickly. Magnetized components can assist in a load/reset action relative to internal components of the power tool. In one example, one or more hammers of a hammer drill/driver can be reset more efficiently when various magnetized elements are oriented in certain ways relative to one another. Additionally, friction between components can be reduced by repulsive magnetic fields between two or more components. Utilizing the magnetic fields can improve the overall function of internal components of the tool. In another example, a tool such as a nailer or stapler can utilize magnetism to assist its internal components. In a nailer or stapler the magnetism can assist, for example, acceleration and deceleration of components utilized to drive the nail/staple.
