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.
Claims16
A power tool comprising:
- a housing;
- a first handle and a second handle, the first handle and the second handle configured to facilitate two-handed operation of the power tool;
- 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;
- 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;
- a fluid supply coupled to the power tool;
- and
- a sensor configured to detect a presence of the fluid supply;
- wherein a rotation of the at least one cutting wheel is configured to be automatically switched by the at least one switch to the forward rotational direction based on the presence of the fluid supply.
A system comprising:
- a removable and rechargeable battery pack;
- and
- a power tool including:
- a housing configured to receive the removable and rechargeable battery pack,
- a motor located within the housing,
- a drive assembly located within the housing and connected to an output of the motor,
- a first handle and a second handle, the first handle and the second handle configured to facilitate two-handed operation of the power tool,
- at least one cutting wheel coupled to the drive assembly,
- 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;
- a fluid supply coupled to the power tool;
- and
- a sensor configured to detect a presence of the fluid supply;
- wherein a rotation of the at least one cutting wheel is configured to be automatically switched by the at least one switch to the forward rotational direction based on the presence of the fluid supply.
A method for cutting a surface, the method comprising:
- activating a power tool including a housing, a motor located within the housing, a drive assembly located within the housing and connected to an output of the motor, a first handle and a second handle configured to facilitate two-handed operation of the power tool, at least one cutting wheel coupled to the drive assembly, and at least one switch;
- controlling activation of the motor for directional rotation of the drive assembly in a forward rotational direction when the at least one switch is in a first state;
- coupling a fluid supply to the power tool;
- detecting, via a sensor, a presence of the fluid supply, and
- automatically switching, by the at least one switch, a rotation of the at least one cutting wheel to the forward rotational direction based on the presence of the fluid supply;
- controlling activation of the motor for directional rotation of the drive assembly in a reverse rotational direction when the at least one switch is in a second state;
- and
- advancing the power tool toward the surface to cut the surface.
