An apparatus for removing debris from a well is provided. The apparatus comprises a tool body having a head, a chamber, a connector, a conduit, and a filter. The head has an opening and comprises protrusions extending from the outer surface for moving debris. The chamber is in the tool body to store debris. The connector is for attaching the tool body to a drilling system. The conduit is connected to the opening in the head to convey debris and fluid from the well to the chamber. The filter is in the tool body to limit the size of the particles that can pass into the drilling system from the chamber. In use, fluid flow and the protrusions move the debris from the well and through the apparatus.
