Abstract: 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.

Abstract: 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.

Abstract: Track saws with self-adjusting rib-guide assemblies and methods of operating self-adjusting rib-guide assemblies of track saws are disclosed herein. The track saws include a motor, an arbor, and a base plate. The base plate defines an arbor-facing side and an arbor-opposed side. The base plate includes a rib-receiving channel and a self-adjusting rib-guide assembly. The self-adjusting rib-guide assembly at least partially defines the rib-receiving channel and is configured to automatically accommodate a range of raised rib transverse widths. The methods include positioning a raised elongate rib of the track within a rib-receiving channel of a base plate of the track saw. During the positioning, the methods also include establishing a contact force between the raised elongate rib and the self-adjusting rib-guide assembly. Responsive to the contact force, the methods further include moving at least a portion of the self-adjusting rib-guide assembly relative to a remainder of the track saw.

Abstract: 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.

Abstract: A handheld machine saw having a saw assembly, which has a saw toolholder for a saw tool and a saw drive motor for driving the saw toolholder, and having a guide device, which has a guide body having a guide surface extending along a longitudinal axis for guiding the handheld machine saw along a working direction on a workpiece or a guide rail, wherein the handheld machine saw has a scoring assembly, which is arranged in front of the saw assembly on the guide device with respect to the working direction, having a scorer toolholder for a scoring tool and having a scoring drive for driving the scorer toolholder, wherein a score upstream from the saw cut to be introduced in the working direction can be introduced into the workpiece by means of the scoring tool protruding in front of the guide surface in scoring operation of the handheld machine tool.

Abstract: The present disclosure relates to a fluid connector having a sleeve-like connection piece with a connection-piece inner wall and an annular stop collar formed in the interior of the sleeve-like connection piece, said stop collar having an axially directed stop face, and a plastics tube which has a tube inner wall, a tube outer wall and a tube front face. The tube front face of the plastics tube comes into contact with the axially directed stop face. The tube outer wall of the plastics tube is connected to the connection-piece inner wall of the sleeve-like connection piece by means of a friction-welded connection.
