Compound miter saw
A compound miter saw (1; 70; 90) includes a turntable-fixing mechanism (40) and a tilt-fixing mechanism (60; 80; 100) configured to respectively fix the miter angle and tilt (bevel) angle of a cutting-machine main body (10). The turntable-fixing mechanism includes a fixing rod (42) configured to lock rotation of a turntable (4; 91) relative to a base (2) by manually rotating a grip (41) attached thereto, and is disposed forward of a front surface of a table-extension part (5; 71; 92), downward of an upper surface of the turntable, and at the center of the table-extension part in the left-right direction. The tilt-fixing mechanism includes a manually rotatable tilt-fixing manipulatable part (61; 81; 101) provided between the front surface of the table-extension part and the grip. A rotary shaft (61a; 82a; 102a) of the tilt-fixing manipulatable part is coaxial with the fixing rod (rotary shaft) attached to the grip.
CUTTING MACHINE
An illuminator that emits light from a radially outer portion of the cutting tool toward the cutting tool includes a first light source and a second light source, and a first lens and a second lens. The first lens has a first emission surface including a first outermost portion located farthest and at a first distance from a first center axis including a first light source center of the first light source and perpendicular to the first light source. The second lens has a second emission surface including a second outermost portion located farthest and at a second distance from a second center axis including a second light source center of the second light source and perpendicular to the second light source. A distance between the first center axis and the second center axis is shorter than a sum of the first distance and the second distance.
Miter saw
A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and an upper blade guard covering an upper portion of the saw blade. The miter saw also includes a cut line indicator coupled to the upper blade guard. The cut line indicator includes a light source, a cover positioned between the saw blade and the light source, a housing in which the light source is positioned, a rib coupled to one of the cover or the housing, and a first slot defined in the other of the cover or the housing. The cover includes a second slot through which light from the light source passes to illuminate opposite sides of the saw blade and a work piece supported upon the base assembly, thereby casting a shadow of the saw blade onto the work piece. The rib is receivable within the first slot to align the second slot with the saw blade.
POWER TOOL BLADE TYPE DETECTION AND AUTOMATIC SPEED ADJUSTMENT
Systems and methods are provided for an electric tool (e.g., a power tool) that includes an output driver for receiving an accessory, and an accessory-type detector. A motor of the electric tool is coupled to the output driver for driving the accessory. The power tool also includes an operation trigger for activating the motor and a motor controller. The motor controller includes an electronic processor that is coupled to the accessory-type detector, the motor, the operation trigger, and a memory. The memory stores instructions that when executed by the electronic processor cause the motor controller to detect a characteristic of the accessory from output of the accessory-type detector. The motor controller determines an operational characteristic for the accessory based on the detected characteristic, and controls operation of the motor to drive the accessory according to the operational characteristic when the operation trigger is activated.
Blade guard for saw of saw house and method
A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.
Table saw and miter saw combination apparatus
A table saw and miter saw combination apparatus for combining the functionalities of table saws and miter saws includes a table housing having a table blade slot extending through to a table inside. A table saw is coupled to the table housing within the table inside and has a table blade extending through the table blade slot. The table saw has a power switch coupled to the table front side. A miter housing is coupled to the table housing. The miter top side has a base cutout. A miter base is coupled to the miter housing being pivotably coupled within the base cutout. The miter base has a miter blade slot extending therethrough. A miter saw is coupled to the miter housing. The miter saw has a miter arm. The miter saw has a miter handle coupled the miter arm. The miter handle has a power trigger.
Miter saw
A benchtop cutting machine (1), such as a miter saw, includes: a base (2); a turntable (3), which is rotatable relative to the base; and a lock mechanism (40), which locks the rotation of the turntable relative to the base. The lock mechanism comprises a locking pin (45), which is movable along its axial direction and locks the rotation of the turntable by engaging with the base, and a manipulatable lever (41), which is pivotable in an up-down direction to release the engagement of the locking pin from the base. The manipulatable lever has a pivot point or center of rotation (42) that is located upward of the locking pin.
Rail stop system for a sliding saw
A rail system for a power tool has a base defining a work surface for supporting a workpiece, a support mounted to the base, a number of elongated rails slidably supported by the support for movement relative thereto, a yoke engaged to the number of elongated rails for movement with the elongated rails, and a power tool assembly supported by a yoke for performing an operation on the workpiece. A rail stop is movably mounted to one of the support and the yoke, the rail stop including a stop surface adapted to abut the other of the support and the yoke when the rail stop is in a first position between the yoke and the support. The rail stop is movable to a second position different from the first position.
Battery adapter for a cutting power tool
A cutting machine reduces cost increase associated with production equipment and has design flexibility for different types of batteries. A cutting machine for cutting a workpiece includes a cutting machine body including a cutting blade, a motor that drives the cutting blade, and a motor housing accommodating the motor, and an adapter including a body holder attached to the cutting machine body and a battery holder in which a battery to power the motor is installable.
Power tool
A power tool includes a motor; a fan configured to be rotated by the motor to generate a cooling air; a housing accommodating therein the motor and the fan and defusing an air passage for the cooling air; an output shaft rotatable by the motor; and a transmission mechanism configured to transmit rotation of the motor to the output shaft. An end bit being attachable to and detachable from the output shaft. The transmission mechanism includes an intermediate shaft provided in the housing, a first belt transmitting a rotational force of the motor to the intermediate shaft, a second belt transmitting a rotational force of the intermediate shaft to the output shaft, and a rotation member transmitting a rotational force of the second belt to the output shaft. The first belt and the second belt are positioned inside a space through which the cooling air passes.
