Abstract: A dust collection cup includes a cylindrical attachment to cause a bit to extend through the attachment, a cylindrical dust collector located in front of the attachment to cause the bit to extend through the dust collector, a seal between the attachment and the dust collector and having a through-hole to receive the bit, and a connection port connectable to a dust collection hose and located on an outer circumferential surface of the attachment outward in a radial direction of the bit from the seal and rearward from the seal. The connection port has a distance in the radial direction of the bit from an axis of the attachment to an outermost position longer than a distance in the radial direction of the bit from the axis to a position on the outer circumferential surface of the attachment that is opposite to the outermost position from the axis.

Abstract: A driving tool comprises a cylinder extending in an up-down direction and a piston that moves downward within the cylinder due to a compressed gas to drive a driving member. The driving tool further comprises a main body housing that houses the cylinder and a grip extending rearward from a rear surface of the main body housing. The driving tool further comprises an upper chamber that is provided above the cylinder and communicates with the cylinder. The driving tool further comprises an air chamber that extends downward from the upper chamber and that extends only in an area on a right or left side of the main body housing with respect to both an axis center of the cylinder and an axis center of the grip.

Abstract: An electric work machine (1; 110; 120; 130), such as a power tool, includes a motor (11) having a rotor, a drive part (13) that supplies electric currents to drive the motor, a rotational-direction selection part (17), and a motor-control part (14; 31, 32, 40, 50, 60; 14, 40, 60, 73, 80; 14, 60, 91). The rotational-direction selection part is configured for manually setting (selecting) the rotational direction of the rotor and outputs first and second setting signals that each indicate the set (selected) rotational direction. The motor-control part controls the drive part such that the rotor rotates in the rotational direction indicated by the first setting signal and/or the second setting signal. In response to a determination that the rotational directions indicated by the first and second setting signals are inconsistent, the motor-control part stops or prevents the drive of the motor.

Abstract: A tube expansion tool includes a female screw member that rotates by an electric motor. A screw shaft engages the female screw member to move in a front-rear direction. A front-end position sensor detects that the screw shaft has reached a front-end position. The screw shaft stops moving forward by a braking operation. A controller controls the braking operation of the electric motor. When the controller determines that the screw shaft has reached the front-end position based on a signal from the front-end sensor, the controller performs the braking operation. Also, when the controller detects that the screw shaft stops, the controller rotates the electric motor in a reverse direction to move the screw shaft rearward.

Abstract: A power tool includes a spindle, a housing, a cover body configured to be removably mounted to the housing, a first engagement part provided on or in the cover body, and a second engagement part provided on or in the housing. The cover body includes an upper plate part and an outer peripheral part. The second engagement part is movable between an engagement position and a disengagement position. The first and second engagement parts are configured to restrict rotation of the cover body around the drive axis relative to the housing by engaging with each other. The first engagement part is (i) at a same location as or radially outward of the outer peripheral part of the cover body in a radial direction orthogonal to the drive axis, and (ii) between an upper end and a lower end of the cover body in the up-down direction.

Abstract: A long rod polishing device includes a prismatic or columnar battery, a battery mounting portion, an electric motor, a pad, and a rod portion. The battery is mountable to the battery mounting portion. The electric motor is driven by an electric power from the battery. The pad has a polishing surface and moves by a driving force from the electric motor. The rod portion has an end portion to which the pad is coupled. The battery mounted to the battery mounting portion has a longest side. The longest side has a direction so as to form an angle with respect to a second imaginary straight line. The second imaginary straight line is perpendicular to both of a center axis of the rod portion and a first imaginary straight line. The first imaginary straight line is perpendicular to the center axis and parallel to the polishing surface of the pad.

Abstract: A reciprocating tool includes a body housing, a handle member and an elastic member. A first one of the body housing and the handle member includes a first coupling part, while a second one includes a second coupling part. The first coupling part includes an internal space, and an opening that communicates with the internal space and an outside space of the first coupling part. At least a portion of the second coupling part protrudes into the internal space through the opening and is movable relative to the first coupling part in the front-rear direction within the opening. The elastic member is disposed in the internal space and is configured to bias the first coupling part and the second coupling part such that the body housing and the handle member are biased away from each other in the front-rear direction.
