Abstract: A portable cutting device having a cutting tool for cutting a material. The cutting device includes a motor driving the cutting tool and a shroud at least partially enclosing the cutting tool. The shroud defines a debris accumulation chamber for gathering debris created by the cutting tool cutting the material. An impeller is operatively coupled to the motor and driven by the motor to create suction pressure to draw the debris out of the debris accumulation chamber and into a collection bag.

Abstract: A circular saw includes a motor, a blade axle operably connected to the motor and configured to support a blade, and a footplate configured to support the motor above a workpiece at a reference position in which the blade is positioned with zero bevel. The circular saw further includes a blade guard that is rotatable about the axis of rotation from a closed position to an open position and includes an anti-snag structure with a front end portion and a trailing edge portion. The anti-snag structure includes a linear leading edge located between the front end portion and the trailing edge portion, and is configured such that when the footplate is at the reference position and the blade guard is in the closed position, a line extending through the axis of rotation and perpendicular to the footplate when viewed from a side elevational view passes through the linear leading edge.
