Abstract: A saw including a lockout mechanism having a lever and a plunge stop. The lever has a trigger abutment surface and is movable between a safety position in which the trigger abutment surface inhibits actuation of a trigger and a use position in which the trigger abutment surface permits actuation of the trigger. The plunge stop is coupled to the lever and is movable with the lever between a first position and a second position. The first position corresponds with the safety position of the lever. In the first position, the plunge stop inhibits a motor housing of the saw from being moved from a raised position toward a plunged position. The second position corresponds with the use position of the lever. In the second position, the plunge stop permits the motor housing to be moved from the raised position toward the plunged position.

Abstract: A sliding cutting machine (1) includes: slide bars (51); a slide base (52), which slides along the slide bars; and a cutting-machine main body (10), which is swingable in an up-down direction about an up-down swing (pivot) shaft (10a) provided on the slide base. The cutting-machine main body includes: an output shaft (37) extending in an axial direction orthogonal to the slide bars and mounting a cutting tool (11); an electric motor (23) between the cutting tool and the slide bars when the cutting tool is vertical, and located more upward than the slide bars; and a motive-power transmitting part (30) transmitting the driving force of the electric motor to the output shaft. The motive-power transmitting part is between the cutting tool and the slide bars and upward of the slide bars when the cutting-machine main body is at a top dead center.

Abstract: A power tool is provided including a tool housing, a brushless DC (BLDC) motor assembly disposed within the tool housing, and a power module including a printed circuit board (PCB) and power switches mounted on the PCB and electrically coupled to the motor assembly. The PCB includes a width that is greater than a diameter of the motor assembly. A mounting bracket is secured to an end of the motor assembly and includes a mating portion arranged to mate with the end of the motor assembly, mount posts extending radially-outwardly from the mating portion, and axial walls extending between outer ends of the mount posts and at least partially housing the power module to support the PCB in a substantially parallel orientation relative to the rear end of the motor assembly.

Abstract: A compound saw includes a base, a housing, a transmission component and a table, the rear end of the table is rotatably connected to the housing, and is engaged with the cutter head through the transmission component, so as to expose the cutter head out of the first cutting slit or out of the second cutting slit when the front end of the table swings upward and downward. The cutter head of the compound saw can be switched between the bench cutting mode and the miter cutting mode. Accordingly, on one hand, the structure for switching between modes is simple and does not require the cooperation of too many parts; on the other hand, the switchover can be realized simply by manually operating the movable bench, without too many operations.

Abstract: A miter saw has a base having a detent notch, a table rotatably connectable to the base, a pivoting assembly connected to the table, and a saw assembly supported by the pivoting assembly. The saw assembly has a blade movable downwardly for a cutting operation. A locking mechanism is disposed on the table. The locking mechanism is movable between an unlocked position and a locked position for selectively unlocking and locking the table for rotational movement relative to the base about the miter axis. The locking mechanism has a lock lever rotatably connected to the table. The lock lever has a handle for moving locking mechanism between the locked and unlocked positions. The saw also has a miter detent assembly for selectively engaging and disengaging the detent notch.

Abstract: A sliding compound miter saw slide device allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The sliding saw slide device integrates an adjustment or alignment mechanism configured to move an upper base portion of the saw base relative to a lower base portion of the saw base. In addition, a sliding saw stand allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The sliding saw stand integrates an adjustment or alignment mechanism configured to move an upper miter saw mount member/plate relative to the saw stand base/base frame.

Abstract: A fine adjuster for finely adjusting the lateral tilt position of a cutting machine body has improved operability. A cutting machine includes a table, a cutting machine body, a tilting member supporting the cutting machine body in a manner laterally tiltable relative to the table, a tilting locking member, and a lever member to adjust the tilt position of the cutting machine body. The lever member includes a fulcrum coupled to the table in a manner rotatable about an axis, a load point coupled to the tilting member, and an effort point extending from the fulcrum and located at a distance from the fulcrum greater than a distance between the fulcrum and the load point.
