A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and a lower blade guard covering a lower portion of the saw blade. The miter saw also includes a linkage for raising the lower blade guard to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly. The linkage is operable to apply a force to the lower blade guard for holding the lower blade guard in a raised position, without any input from the operator of the miter saw and without changing the length of the linkage, to facilitate changing the saw blade.

A power tool includes a housing having a motor housing portion and a handle portion coupled thereto, an arbor supported by the housing, a working element attachable to the arbor for movement therewith, a motor positioned within the motor housing portion and configured to drive the arbor, a first lighting element positioned proximate an end of the handle portion, and a second lighting element positioned on the motor housing portion. The first lighting element is configured to illuminate a workpiece behind the working element and the second lighting element is configured to illuminate the workpiece in front of the working element.

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.

Circular saws that include blade mounts for circular saw blades and methods of attaching circular saw blades to circular saws are disclosed herein. The circular saws include a motor, an arbor, and a blade mount. The motor includes a motor shaft configured to rotate about a shaft rotational axis. The arbor is configured to receive a torque from the motor when the motor shaft rotates about the shaft rotational axis. The blade mount is operatively attached to the arbor and is configured to selectively and operatively attach a circular saw blade to the arbor. The blade mount includes an inner flange that includes an inner flange blade-contacting surface that faces away from the motor. The inner flange is free from any structure that projects away from the motor and also away from the inner flange blade-contacting surface.

Circular saws are disclosed herein. The circular saws include a cutting assembly, a base plate, a pivot assembly, and a pivot bias mechanism. The cutting assembly includes a motor and an arbor. The base plate defines an assembly-facing side and an assembly-opposed side. The pivot assembly operatively attaches the cutting assembly to the base plate. The cutting assembly and the base plate are configured to operatively rotate, relative to one another and about a pivot axis of the pivot assembly, to selectively vary a region of the circular saw blade that extends on the assembly-opposed side of the base plate. The pivot bias mechanism is configured to apply a linear force between the cutting assembly and the base plate in a linear bias direction that urges the cutting assembly and the base plate in opposed directions along the pivot axis.

Handheld circular saws with improved cutting capabilities are disclosed herein. The handheld circular saws include a motor and an arbor, which is configured to operatively attach a circular saw blade to the handheld circular saws. In some examples, the handheld circular saws include the circular saw blade, the circular saw blade has a blade diameter, the handheld circular saw has a maximum depth-of-cut, and a ratio of the maximum depth-of-cut to the blade diameter is at least 0.35 and at most 0.45. In some examples, the handheld circular saw includes a base plate that defines an arbor-facing side. In some such examples, at least 95% of the handheld circular saw is fully contained within a footprint of the handheld circular saw. In some such examples, an entirety of the handheld circular saw may be contained within a base plate width of the base plate.

Bevel saws configured to make a bevel cut in a workpiece are disclosed herein. The bevel saws include a motor and an arbor configured to operatively attach a circular saw blade to the bevel saws and to rotate the circular saw blade within a blade plane. The bevel saws further include a base plate that defines an arbor-facing side and an arbor-opposed side. The arbor is operatively attached to the arbor-facing side of the base plate. The bevel saws also include a bevel guide configured to selectively vary a bevel angle between the blade plane and the arbor-opposed side of the base plate within a bevel cut angular range-of-motion to selectively vary an angle of the bevel cut within the workpiece. The bevel saws may include a bevel guide mount configured to operatively attach the bevel guide to the base plate.

Circular saws with lock assemblies are disclosed herein. The circular saws include a motor including a motor shaft configured to rotate about a shaft rotational axis. The circular saws also include an arbor configured to operatively attach a circular saw blade to the circular saw. The circular saws further include a switch configured to selectively apply an electric current to the motor and a switch lever configured to be selectively actuated, by a user of the circular saw and via an actuation force, to actuate the switch and direct the switch to apply the electric current to the motor. The lock assemblies include a switch lock, which defines a switch-locked configuration, in which the switch lock resists actuation of the switch lever by the user, and a switch-unlocked configuration, in which the switch lever is free to be actuated by the user.

A concrete saw is disclosed and includes a frame having a platform and a leg pivotably coupled to the platform at a pivot axis, at least two rear wheels coupled to the platform at the pivot axis, at least one rear wheel coupled to an end of the leg distanced from the pivot axis, a power and drive assembly disposed on the platform, wherein the power and drive assembly includes an electric motor and a battery pack coupled to the electric motor to provide direct current power to the electric motor, and a cutting assembly driven by the power and drive assembly to cut a groove in a work surface as the concrete saw is moved across the work surface.
