A circular saw includes a shoe, a shoe plate, a saw unit, and a trim angle adjustment mechanism. The saw unit includes a circular saw blade defining a blade plane, and the saw unit is coupled to the shoe by a shoe plate. The trim angle adjustment mechanism is operable to adjust a trim angle between a trim axis formed at an intersection of the blade plane and the shoe plane and a reference trim axis, the reference trim axis being parallel to a groove in a track along which the circular saw is slidable. The trim angle is adjustable to align the trim axis with the reference trim axis in response to sliding movement of the shoe plate relative to the shoe, the sliding movement caused by adjustment of the trim angle adjustment mechanism.

A foldable miter saw includes a base unit, a worktable, a cutting unit, and a safety device. The cutting unit can be set between a working position where the saw blade and the worktable define therebetween a contained angle within 9045 angle and a folded position where a stoppage signal is provided to power off the driver. The arrangement of the safety device enables a power supply to be cut off from the driver automatically when the cutting unit is moved to the folded position.

A multiple function saw includes a base including an arm selectively movable with respect to the base, the arm being selectively rotatable about a first arm axis at a first end of the arm, towards and away from a substantially planar top surface of the base. A saw having a housing is coupled to the arm at a second end of the arm. The multiple function saw is adjustable to operate in multiple different modes including a first mode with the arm being selectively rotatable about the first arm axis, a second mode with the arm being constrained from rotating about the first arm axis, the arm being substantially stationary with respect to the base, wherein the saw is pivotable about a vertical axis at the second end of the arm such that a face of a saw blade is positionable to operate as a table saw, and a third mode with the saw being moveable horizontally along the base to operate as a radial saw.

A miter saw includes a base assembly, a bevel arm pivotably coupled to the base assembly, and a saw unit pivotably coupled to the bevel arm about a horizontal chop axis. The saw unit includes a saw blade rotatable about a blade axis and a motor having an output shaft inclined at an oblique included angle relative to the blade axis. The miter saw also includes a guide rail coupling the saw unit to the base assembly and a battery selectively electrically connectable with the motor to provide power to the motor. The bevel arm and saw unit are pivotable relative to the base assembly, from an orientation in which the saw blade is substantially vertical, in both a first direction about the bevel axis by a bevel angle of at least about 45 degrees and an opposite, second direction by a bevel angle of at least about 45 degrees.

A sliding cutting machine (1) includes: at least one slide bar (51) having an elongated shape; a slide base (17) slidably mounted on the at least one slide bar (51); and a cutting-machine main body (10) mounted on the slide base (17) such that it is movable in an up-down direction relative to the slide base (17). The cutting-machine main body (10) includes: an output shaft (27) that extends in an axial direction orthogonal to an extension direction of the at least one slide bar (51) and on which a cutting tool (11) is mounted; and an electric motor (21) disposed between the cutting tool (11) and the at least one slide bar (51), as viewed along the extension direction of the at least one slide bar (51), while the output shaft (27) is rotating and the cutting tool (11) is vertical.

A power miter saw includes a base assembly including a frame, cavities on a bottom of the frame, two supports at two sides of the frame respectively, and two parallel sliding rods passing through one support; a table assembly including a rotatable table mounted on the frame, a miter arm secured to the rotatable table, and a fence at an edge of the rotatable table and secured to the supports; and a saw blade and motor assembly. The fence includes a central curved top, two platforms at two ends of the central curved top respectively, two shoulders each at a joining portion of the curved top and the adjacent platform, and two aligned grooved members each extending outward from a position proximate the platform. The platforms are at an elevation greater than that of the miter arm.

A tile saw includes a base, a frame assembly disposed on the base, a first rail disposed on the frame assembly, the first rail having a longitudinal axis, a table slidingly disposed on the first rail, a support assembly disposed on the base, a saw assembly supported by the support assembly, the saw assembly comprising a motor, a cutting wheel driven by the motor, the saw assembly being pivotable about a horizontal axis substantially parallel to the longitudinal axis, and a switch electrically connected to the motor and disposed on the support assembly so that, when the motor assembly is pivoted about the horizontal axis, the switch remains stationary.

A tile saw includes a base, a frame assembly disposed on the base, a first rail disposed on the frame assembly, the first rail having a longitudinal axis. A table is slidingly disposed on the first rail and a support assembly is disposed on the base. A fence assembly is attachable to the table and has a first fence and a second fence for contacting the workpiece. The second fence is pivotably attached to the first fence and pivotable about a substantially horizontal axis. A saw assembly is supported by the support assembly and includes a motor, and a cutting wheel driven by the motor.

Foldable miter saws and a folding method of miter saws are disclosed. The foldable miter saws includes a base unit, a worktable, and a cutting unit. The cutting unit includes a support arm pivotally mounted on the worktable, a saw blade, and a driver. The miter saw folding method includes the step of biasing the cutting unit relative to the base unit and the step of rotating the support arm relative to the base unit and the worktable to change the cutting unit from a working position to a folded position, thus reducing the vertical space occupied by the cutting unit and facilitating delivery, storage and package of the foldable miter saws.

A device for setting the miter angle of a machine tool is disclosed. The device includes a clamping block having at least one slot, and a pivot lever on which the machine tool can be mounted and which is pivotable about a pivot point relative to the clamping block between a minimum and a maximum miter angle. The slot includes at least two stop elements offset relative to one another. A setting mechanism includes a lever element for the selection of a maximum miter angle, where the lever element includes a mating stop element is alignable in such a way corresponding to the rotational alignment of the lever element that the mating stop element is able to strike the respective stop element in accordance with the selected maximum miter angle and by which the pivoting movement of the pivot lever relative to the clamping block can be limited.
