Abstract: A hammer drill comprising a body (2) containing an electric motor (4) for driving an output (6) of the drill is disclosed. A vibration transducer (12) senses vibrations generated by the motor and produces a vibration signal dependent upon the sensed vibrations. An electronic module (10) includes a controller (10a) for controlling the rotational speed of the motor, and a signal processor (10b) for receiving the vibration signal from the vibration transducer, determining the rotational speed of the motor based on the vibration signal, and providing an output signal to the controller to cause the controller to control the rotational speed of the motor.

Abstract: 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.

Abstract: An impact drill includes a first ratchet rotating along with a spindle and movable in an axial direction, a second ratchet engaged with the first ratchet and movable in a axial direction but unrotatable, and a spring provided between the second ratchet and a partial member of a housing. An amount of movement of the spindle in the axial direction is regulated, so that the pressing force is too excessive, the restoring force of the spring urging the second ratchet is controlled to maintain a state of generating a set stroke force.
