Abstract: A reciprocating cutting tool includes a shoe that is less likely to slip off when pulled frontward, for positioning the shoe, beyond a predetermined position such as a maximum pull position. The reciprocating cutting tool includes a motor, a slider being rod-like and including a tip tool holder, a reciprocation converter that converts rotation of the motor to reciprocation in a direction in which the slider extends and transmits the reciprocation to the slider, a shoe slidable in a front-rear direction to come in contact with a workpiece to which the tip tool is applied, a shoe lock unit engageable with the shoe to restrict the shoe from sliding and disengageable from the shoe to allow the shoe to slide, and a pin that interferes with the shoe slid to a predetermined position.

Abstract: 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.

Abstract: An easily operable, highly durable cutting machine finely adjusts the miter angle of a turntable. A cutting machine includes a turntable supported in a manner rotatable horizontally to a base and including a substantially disk-shaped table body to receive a workpiece and a table extension protruding forward from the table body, a cutting machine body located above the turntable and connected in a manner swingable vertically to the turntable, and a fine angle adjuster that adjusts a rotation angle of the turntable with respect to the base and including a rack on the base, a pinion located in the table body within an area of the table body as viewed from above and engageable with the rack directly or indirectly, and an operation part operable to rotate the pinion.

Abstract: A grease discharge device includes a motor, a plunger, a grease supply unit, a pump, a check valve, and a relief valve. The plunger reciprocates by driving of the motor. The grease supply unit supplies grease to a forward movement side with respect to a backward movement side dead center of the plunger. The pump performs a discharge behavior of the grease by the reciprocation of the plunger. The check valve is disposed at a downstream side with respect to a forward movement side dead center of the plunger in a discharge path of the grease inside the pump. The relief valve is disposed between a supply portion of the grease by the grease supply unit and the check valve. The relief valve releases the grease inside the discharge path to the grease supply unit side according to a pressure rise inside the discharge path.

Abstract: A reciprocating cutting tool reduces deteriorating movement of an operating drum due to entry of chips between the operating drum and a housing. A reciprocating cutting tool includes a motor, a slider being rod-like and extending in a front-rear direction, a reciprocation converter that converts rotation of the motor to reciprocation in the front-rear direction and transmits the reciprocation to the slider, a power transmission housing accommodating the reciprocation converter, a tip tool holder at a front end of the slider to detachably receive a tip tool, and an operating drum operable to attach or detach the tip tool with the tip tool holder through rotation. The operating drum is rotatably held on the power transmission housing with one or more ring members.

Abstract: 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.

Abstract: 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.
