A shaft cutting tool incorporating a scissor assembly having a first arm, a second arm, and a hinge interconnecting the arms' proximal ends; a shaft mount attached to the first arm's distal end; and a cutting wheel assembly operatively mounted within a hollow bore formed at the second arm's distal end; wherein the cutting wheel assembly includes a drive axle and rotary bearing; and wherein the drive axle extends oppositely from the cutting wheel for engagement with a portable electric drill.

An improved cutting device with an integrated and interruptible auxiliary power supply. In a preferred embodiment, the improved cutting device is a miter saw having a trigger mechanism for controlling a cutting implement, and at least one 120V or 240V auxiliary power outlet. Electrical power is only provided to the cutting implement and the auxiliary power outlet when the triggering or a similar mechanism is activated, and the release of the triggering mechanism by the user automatically shuts off electrical power to both the cutting implement and the at least one auxiliary power outlet. The auxiliary power outlet is useful for powering any number of different accessories including, without limitation, a light, vacuum source, etc., and is repositionable.

A multi-link miter saw includes a base, a table supported on the base, a supporting unit connected to the table, a linkage unit connected to the supporting unit, a cantilever arm unit including a cantilever arm pivotally connected to the linkage unit and a connection member pivotally connected between the cantilever arm and the linkage unit for enabling the cantilever arm to be driven by the linkage unit and the connection member to move along a horizontal axis between the rear edge and front edge of the base, and a cutting unit pivotally connected to the cantilever arm unit. Based on the arrangement of the linkage unit and the cantilever arm unit, the cutting unit can be moved smoothly relative to the table, thus enhancing operation stability.

A cutting device may include a friction reducing device arranged in an operational force transmission path between an operation member and a fixing device that can fix a circular cutter to a rotational shaft of a cutting unit.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.

A bevel angle lock and detent system for a miter saw includes a first locking unit fixed relative to the turntable and a second locking unit coupled to a bevel arm of the miter saw. An actuator is moveable between a first position and a second position to move the second locking unit relative to the first locking unit. In the first position, a brake member of the second locking unit is engaged with an arcuate surface of the first locking unit to lock a saw unit relative to a turntable. In the second position, the brake member is disengaged from the arcuate surface, thereby permitting pivoting movement of the saw unit, and a detent member of the second locking unit is engageable a detent aperture of the first locking unit to locate the saw unit relative to the turntable at one predetermined bevel angle.

A miter saw has a base assembly, a table rotatably disposed on the base assembly, a support section rotatably connected to the table, a guide bar fixedly attached to and extending forwardly from the support section, and a saw assembly sliding along the guide bar. The saw assembly is pivotable downwardly for cutting a workpiece disposed on the table. A handle is disposed adjacent to a forward end of the guide bar. The handle is movable between a first position for fixing a rotational position of the support section relative to the table, and a second position for allowing rotational movement of the support section relative to the table.

A miter saw and a workpiece support are provided. The workpiece support has a circular disc-shaped turntable penetrated by a saw blade slot serving as a passage for the saw blade lowered into the working position, a holder on one side for fastening the saw unit, and a radial arm which extends the turntable and the saw blade slot in the longitudinal direction of the slot radially outwards on a side opposite the holder. A radial arm connection is provided, on which the radial arm is detachably and co-rotatably attached to the turntable, or on which a radially outer radial arm outer portion of the radial arm is detachably and co-rotatably attached to a radially inner radial arm inner portion of the radial arm formed integrally with the turntable. The miter saw has blade that can be moved transversely and lowered from a position above the workpiece support.
