Abstract: A circular saw includes a motor operatively connected to rotate a saw blade that forms a cutting plane and a fixed blade guard that surrounds a portion of the saw blade. The circular saw additionally includes at least one light source that is mounted to the fixed blade guard and emits a beam that forms a first linear optical alignment marker on a workpiece in a first direction, and emits a beam that forms a second linear optical alignment marker on the workpiece in a substantially second opposite direction.

Abstract: A saw includes a housing, a motor, a saw blade, a base plate, and an alignment guide. The motor is at least partially provided in the housing. The saw blade is driven by the motor and defines a cutting plane. The base plate supports the housing. The alignment guide is attached to the base plate and has a laser, a scale, and an indicator. The laser is selectively rotatable and projects a laser beam in a laser plane about a first axis. The scale is positioned about the first axis and has a plurality of first graduations. The indicator is aligned with the scale and indicates a horizontal offset distance between the cutting plane and the laser plane along the base plate.
