Abstract: A tool includes a prime mover, switch, operation member for the switch, first accessory, second accessory, third intermediate member moved in conjunction with displacement of the operation member, first intermediate member configured to be displaced from a first blocking position of blocking a displacement route of the third intermediate member to a first non-blocking position of not blocking the displacement route by attachment of the first accessory, and second intermediate member configured to be displaced from a second blocking position of blocking the displacement route to a second non-blocking position of not blocking the displacement route by attachment of the second accessory. Only when the first intermediate member is located at the first non-blocking position and the second intermediate member is located at the second non-blocking position, the third intermediate member is permitted to be displaced so that the operation member is permitted to be displaced to the ON position.

Abstract: A work tool includes: a motor; a housing; an operation member extending in a longitudinal direction of the tool along the housing, configured to be pivotal about a pivotal axis by being subjected to a grip operation by a user, and exposed outside the housing on both first and second sides with respect to the pivotal axis; and a switch configured to detect that the operation member is moved to a first startup position in a first direction and to detect that the operation member is moved to a second startup position in a second direction opposite the first. The work tool is configured so that the motor is driven in a case where the pivotal movement to the first startup position is detected by the switch, and that the motor is driven in a case where the pivotal movement to the second startup position is detected by the switch.

Abstract: Grinding chips generated during metalworking are collected, and dust is collected using a dust collector. A metalworking dust collection attachment removably attachable to a grinding tool including a tip tool includes a suction port that collects grinding chips generated during grinding with the tip tool, and a collector connected to the suction port to collect the grinding chips sucked into the suction port. The collector cools the grinding chips.
