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.

A direct current motor controller includes a housing, a plurality of terminals, a first two-way switch, a second two-way switch, an actuating mechanism, and a remote controller plug. The terminals and remote controller plug traverse out of the housing as the first two-way switch, the second two-way switch, and the actuating mechanism are mounted within the housing. A first output terminal, a first power supply positive terminal, and a third power supply negative terminals from the terminals are electrically connected to the first two-way switch. A second output terminal, a second power supply positive terminal, and the third power supply negative terminal from the terminals are electrically connected to the second two-way switch. The remote controller plug is electrically connected to the second power supply positive terminal. The actuating mechanism operatively couples with the first and second two-way switches to toggle and inversely toggle the first and second two-way switches.
