A level indicator attachment for a power hand tool to indicate the angle of inclination of the tool for making cuts at a predetermined angle. In a preferred embodiment, the level indicator comprises a circular bubble level adjustably positioned in a housing and frame mounted to the tool by use of preexisting fasteners used in assembly of the tool. Adjustment of the bubble level in the housing enables the level indicator to be calibrated or adjusted for different angle cuts. The invention is particularly suitable for use in cutting plumb cuts on rafter tails during construction of a building.
