TRIGGER LOCK FOR A MITER SAW
A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a motor for driving a saw blade about a rotational axis, a handle, a trigger coupled to the handle and moveable between a first position in which the motor is deactivated, and a second position in which the motor is activated to drive the saw blade, and a trigger lock pivotably coupled to the trigger for movement therewith to prevent movement of the trigger from the first position to the second position.
CIRCULAR SAW BLADE
In a circular saw blade, cutting teeth are joined to tooth bodies projecting outward in a radial direction at locations on an outer periphery of a disk-shaped metal base, gullets are provided between the tooth bodies so as to be recessed in the radial direction, radial clearance angles of side cutting edges of the cutting teeth are greater than 1 and less than 1, and a vibration prevention mechanism for preventing vibration of the metal base itself is provided. A ratio of a difference between a maximum value and a minimum value of pitches of the multiple cutting teeth to an average value of the pitches is 40% to 100%. A ratio of a difference between a maximum value and a minimum value of average values of depths of the adjacent gullets to an average value of depths of the gullets may be 20% to 100%.
MITER 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.
Tabletop cutting device
Two 18V-type rechargeable batteries are attached in series so as to allow a 36V-type tabletop cutting device to be utilized. By utilizing the 18V batteries which are highly prevalent for electric tools, it is possible to use the 36V-type tabletop cutting device as well as to reduce costs for the batteries.

Tile saw
A tile saw includes a base, and a table movably coupled to the base and moveable in a first plane between a first position and a second position to cut a workpiece. A blade assembly has a saw blade rotatable within a second plane that is perpendicular to the first plane to cut the workpiece as the table moves between the first position and the second position. The tile saw further includes a support arm fixedly coupling the blade assembly to the base via a support arm mount, and an adjustment mechanism received by the support arm mount and the base. The adjustment mechanism is movable between a first adjustment position and a second adjustment position to adjust the position of the saw blade. Adjusting the saw blade includes at least one of translating the saw blade to a third plane parallel to the second plane and pivoting the support arm to change the yaw of the saw blade.
CUTTING DEVICE
A cutting device may include a main body supported on the upper side of a base. The main body includes a rotary blade and a fixed cover partially covering the rotary blade. A handle is attached to the fixed cover and extends rearward therefrom.
SAW MOUNT SYSTEM AND METHOD
Systems and methods for a table-mounted stand that houses a hand-held masonry cut-off saw. In some embodiments, the stand provides a fixed mount that keeps the saw stationary while the operator is allowed to feed the work piece through the saw with both hands. In some embodiments, the stand is configured to mount and un-mount the saw without the need for separate tools or time-consuming restraints. In some embodiments, the stand includes a throttle control that is activated via foot control, which allows for two-hand manipulation of the work piece being cut by the saw mounted on the stand. In some embodiments, the two-handed work-piece manipulation provided by the stand allows for precise curved and multi-angled cuts. In some embodiments, the stand is made of lightweight construction (e.g., aluminum) for ease of setup and mobilization.
CUTTING APPARATUS AND CUTTING METHOD
A cutting apparatus includes: a supply part for supplying an object to be cut; a first cutting part for cutting the object to be cut, provided from the supply part; a carrying part arranged to be consecutive to the first cutting part to carry an intermediate cut object, cut by the first cutting part; and a second cutting part arranged to be consecutive to the carrying part to receive and cut the intermediate cut object from the carrying part, wherein the first and second cutting parts comprise saw blade parts movably and rotatably configured to cut the object to be cut or the intermediate cut object, and the saw blade part has a rotary shaft formed on the upper side of the object to be cut or the intermediate cut object.
CIRCULAR SAW
A circular saw includes a worktable, a sliding unit including a mounting base mounted on the worktable and providing an accommodation slot and two sliding shafts axially slidably inserted through the mounting base at two opposite sides of the accommodation slot in a parallel manner, and a cutting unit including a saw arm pivotally connected between the two sliding shafts and providing an accommodation portion and a saw blade pivotally mounted at the saw arm. Thus, when the saw arm is in an upper limit position, the accommodation of the saw arm is partially disposed outside the accommodation slot. When the saw arm is in a lower limit position, the accommodation portion is received in the accommodation slot. Subject to the design described above, the circular saw achieves the effects of reduced overall dimension, low vibration and high cutting accuracy.
