1. An angle grinder comprising:
a motor;
an output member to which a grinding disc is attachable, the output member defining an output axis;
a drive shaft configured to transfer torque from the motor to the output member, the drive shaft defining a drive axis that is transverse to the output axis;
a braking disc coupled to the drive shaft for rotation therewith;
a braking pad linearly moveable relative to the braking disc in a direction transverse to the drive axis between a first braking pad position, in which the braking pad is in contact with the braking disc, and a second braking pad position, in which the braking pad is spaced from and not in contact with the braking disc;
a biasing member biasing the braking pad toward the first braking pad position; and
a trigger pivotable about a trigger axis between a first trigger position, in which the motor is deactivated, and a second trigger position, in which the motor is activated;
wherein in response to the trigger being pivoted from the first trigger position to the second trigger position, the braking pad is moved from the first braking pad position to the second braking pad position.
