    摘要： An improved dust collector for a power tool is employed. The dust collector includes a body portion, a neck portion and a head portion, wherein the body portion is disposable on the power tool so that during the cutting operation the body portion will receive and direct the air, dust, and debris to the head portion via the neck portion to either be exhausted out or to be collected in a dust collection volume. Preferably, the body portion has a series of openings to allow the user to view the cutting wheel during the cutting operation. The body portion may also have an internal directional member for efficiently directing the flow of air, dust, and debris. The head portion is preferably rotatably connected to the neck portion to allow the user to rotate the head portion to a desired position.

    摘要： A drill includes a housing and a motor coupled to an output member by a transmission. The transmission can selectively couple the output member to an output spindle through a low speed output gear or a high speed output gear for rotating the output spindle at a first speed or a second speed, respectively. Alternatively or additionally, a low speed mode can be provided by actuating an electronic switch that limits the speed of the motor. A rotatably fixed hammer member and a rotatable hammer member can be mounted around the output spindle. A mode collar can be rotatably mounted on the housing and around the output member for movement to positions that correspond to various mode of operation, including a low speed mode, a high speed mode, and a hammer-drilling mode. In the hammer-drilling mode, the transmission operates in the high speed mode.

    摘要： The present invention is directed to an airflow generation and particle dispersion arrangement for a power tool (e.g., an angle grinder). The arrangement includes a motor, an airflow generation assembly, and a particle dispersion assembly. The airflow generation assembly includes a fan driven by the motor. When engaged, the driven fan generates an airstream that is drawn through the power tool. The particle dispersion assembly includes a passive fan that is not driven by the motor, but instead is driven by the airstream. In operation, the passive fan generates centrifugal and mechanical forces sufficient to remove particles from intake air passing through the particle dispersion assembly.

    摘要： A drill includes a housing with a motor coupled to an output spindle via a transmission. A mode collar can be rotatably mounted on the housing for movement that corresponds to different modes of operation. The mode collar can be coupled to an electronic switch to operate a movable member thereof. The coupling can include a switch housing including a slide member, an actuation spring member and a return spring member. The mode collar can have a cam surface and a cam follower in the form of a shift pin that moves the slide member, causing actuation of the switch. The actuation spring member provides a biasing force that is sufficient to overcome a biasing force of a switch spring member to move the movable member into the actuated position. The mode collar can also enable and disable contact between a fixed hammer member and a movable hammer member mounted around the output spindle.

    摘要： The present invention is directed toward a shield assembly for a handheld tool device such as an angle grinder. The shield assembly is selectively repositionable with respect to the cutting tool. A lock mechanism secures the shield assembly in discrete rotational positions relative to the cutting tool. The shield assembly includes a guard member and a bumper member, and an alignment feature configured to align the relative positions of guard member and the bumper member, thereby positing the members in a predetermined relative orientation. With this configuration, the shield assembly is selectively repositionable via a “hands-free” mechanism that permits a user to adjust the position of the shield assembly by simply contacting the shield assembly against a work surface.
