Rotating shaft saw

Abstract

A cutting apparatus may comprise a cutting head having a cutting edge that may be operable to cut through a surface, a pilot drill bit that may be operably coupled to the cutting head, a housing, and an inner shaft that may have at least a portion housed within the housing. The inner shaft may be operably coupled to the cutting head. The inner shaft may also be rotatable to cause the cutting head to rotate according to a rotation of the inner shaft to cut a circular shape. The apparatus may be used to cut through one or more surfaces, such as a soffit and a roof, from underneath the soffit and the roof.
