A power tool comprising a body arranged to support a rotatable work tool rotatable about an axis of rotation, the body comprising a front handle and a rear handle, the power tool comprising a liquid dispensing system for adding a controlled amount of liquid to the rotatable work tool, the liquid dispensing system comprising a valve for adjusting a flow of liquid in the liquid dispensing system, wherein the valve is configured to be controlled by a control member arranged on a portion of the body at which at least part of a conduit transporting the liquid to the rotatable work tool is embedded in the body and separate from the front handle, but adjacent to the front handle such that the control member is operable by a hand gripping the front handle,
wherein the power tool is an electrically powered tool comprising a battery compartment arranged between the front handle and the rear handle, wherein the valve and the control member are arranged between the battery compartment and the front handle,
wherein the axis of rotation is contained in a plane disposed parallel to a baseline of the power tool, and
