  • ANGLE GRINDER
    Publication number: 20200189066
    Abstract: An angle grinder comprises a motor and an output member to which a grinding disc is attachable. The output member defines an output axis. A drive shaft is configured to transfer torque from the motor to the output member. A braking disc is coupled to the drive shaft and a braking pad is moveable in a direction transverse to the drive axis between a first braking pad position and a second braking pad position, in which the braking pad is not in contact with the braking disc. A biasing member biases the braking pad toward the first braking pad position and a trigger is pivotable about a trigger axis between a first trigger position and a second trigger position. In response to the trigger being pivoted from the first to the second trigger position, the braking pad is moved from the first to the second braking pad position.
