Abstract:
A circular saw comprising:a motor for rotatably driving a saw blade about an axis to cut a workpiece in a cutting direction, the saw blade having an inward face facing toward said motor and an outward face, the saw blade defining a cutting plane, a bevel angle being defined between the cutting plane of the saw blade and a surface of the workpiece;a housing supporting said motor and defining an opening through which the inward face of the saw blade is visible;a shoe plate supporting said circular saw on the workpiece to be cut, said shoe plate being pivotably connected to said housing to adjust the bevel angle;a main handle supported by said housing;an auxiliary handle supported by one of said housing and said shoe plate, wherein, in a cutting position and while cutting the workpiece with the saw blade, an operator holds said main handle with one hand and said auxiliary handle with the other hand, said main handle and said auxiliary handle being supported to provide visibility through said opening of the inward face of the saw blade, as the saw blade cuts the workpiece, to an operator from an operator's position rearward of said axis with respect to the cutting direction along a line-of-sight;an indicator for indicating the bevel angle, said indicator being supported by at least one of said housing and said shoe plate, said indicator being supported to provide visibility of said indicator generally along the same line-of-sight; andan air flow control means supported adjacent said opening and controlling a flow of air and debris created by the saw blade wherein said air flow control means includes a tooth supported adjacent said opening to prevent the debris from flowing through said opening.
