Abstract: A power tool includes a housing, a motor located within the housing, a drive assembly located within the housing and connected to an output of the motor, at least one cutting wheel coupled to the drive assembly, and at least one switch configured to control activation of the motor for directional rotation of the drive assembly in either a forward rotational direction or a reverse rotational direction. The drive assembly is configured to operate in the reverse rotational direction during dry cutting. The drive assembly is configured to operate in the forward rotational direction during wet cutting.

Abstract: A bit-removal assembly includes a first ring coupled to an output shaft for co-rotation therewith, a second ring supported on the lower retaining ring of the output shaft, a frusto-conical surface on at least one of the first or second rings, and a wedge positioned between the first and second rings and engaging with the frusto-conical surface. A collar defines a cam surface located radially outward of the wedge. The collar is movable between a locked position, in which the cam surface is engaged with the wedge to displace the wedge radially inward on the frusto-conical surface to separate the second ring from the first ring, and a released position, in which the cam surface is misaligned with the wedge to permit the wedge to move radially outward on the frusto-conical surface. A biasing member urges the collar towards the locked position.

Abstract: A power tool, such as a drilling power tool, configured to perform an easy hole start operation upon actuation of a trigger. When the trigger is actuated, the motor is driven at a low speed value. The motor speed is increased to a second speed value during a predetermined time threshold and then driven at the second speed value until the trigger is no longer actuated. In some embodiments, the easy hole start operation may be implemented by an easy hole start switch. In some embodiments, if the easy hole start operation persists for a time greater than a predetermined time threshold, then the motor will shut off.
