Abstract: Provided is a rotary surface treatment tool for removal of paint and other surface substances from such solid materials as wood. The device has a planar circular base which could be attached to a rotational driver via a center spindle. The front side of the base is has a plurality of planar protrusions such as thin flat wires. The protrusions run along the surface of the front side of the base protruding by a few millimeters and lying at an angle to the plane of the base. During operation, the base revolves around a central rotary axis and the front side of the base is applied to the surface to be treated. The planar protrusions positioned on the front side cut into the surface of the object and tear away surface material.
