A level for indicating the orientation of a surface includes a first planar surface, a second planar surface, and a web coupled to the first planar surface and the second planar surface such that the first planar surface is spaced apart from and is parallel to the second planar surface. A vial defines a long axis and contains a liquid and a gas bubble. The vial is coupled to the web such that the long axis is substantially parallel to the first planar surface. A tube deburring portion is coupled to the web and includes a male conical portion arranged to deburr an inner edge of a tube and a female conical portion arranged to deburr an outer edge of the tube.
