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.

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 track, configured for use with a saw having a blade, including a track body having a side surface, a blade guide, and a splinter strip. The blade guide has an inboard side and an opposite outboard side. The blade guide is movable relative to the side surface between an inboard position in which the inboard side of the blade guide abuts the side surface and an outboard position in which a gap is formed between the inboard side of the blade guide and the side surface. The splinter strip is coupled to the outboard side of the blade guide. The splinter strip is configured to contact the blade to inhibit splintering of a workpiece while being a cut by the blade and the saw is moved along the track body.

A power tool guide assembly includes a power tool guide. The power tool guide has an elongate body having a workpiece side configured to engage a workpiece and a power tool side configured to engage a power tool. At least one elongate rail is mounted on the power tool side. The at least one elongate rail is configured to engage a reciprocal channel in the power tool and limit lateral movement of the power tool in a direction perpendicular to a longitudinal axis of the elongate body wherein the elongate body comprises a connecting rod channel. At least one connecting rod is mountable within the connecting rod channel of the power tool guide. Wherein the at least one connecting rod comprises at least one alignment indication configured to indicate a position of the at least one connecting rod with respect to the power tool guide when mounted within the connecting rod channel.
