摘要： Plunge saws with cut indicators and methods of operating plunge saws are disclosed herein. The plunge saws include a motor and an arbor, which is configured to operatively attach a circular saw blade to the plunge saw and to receive a torque from the motor. The plunge saws also include a base plate and a base plate pivot. The plunge saws further include a plunge mechanism, which is configured to be selectively actuated, by a user of the plunge saw and during operative use of the plunge saw to cut a workpiece, to transition the plunge saw from a retracted orientation to a plunged orientation and to plunge the circular saw blade into the workpiece. The plunge saws also include a cut indicator, which is configured to project a light line onto the workpiece to visually indicate, on the workpiece, a location of an edge of the circular saw blade.

摘要： Circular saws with transparent windows that extend within blade guard openings and cover fastening structures. The circular saws include a motor and an arbor configured to operatively attach a circular saw blade to the circular saw. The circular saws also include a blade guard. The blade guard includes a blade guard opening, which is positioned to permit a user of the circular saw to view a leading edge of the circular saw blade as the circular saw cuts a workpiece. The circular saws also include a transparent window, which extends within the blade guard opening, and a cover fastening structure, which is configured to selectively attach a splinter guard to the blade guard while the transparent window extends within the blade guard opening.
