A miter saw extendable fence attachment for facilitating cutting of long pieces of wood includes a centerpiece that is complementary to a table of a miter saw. The centerpiece is configured for attachment to the table. Each of a pair of extensions comprises a support and a plate. The support is reversibly couplable to a respective opposing end of the centerpiece. The plate extends perpendicularly from a front of the support adjacent to a bottom of the support. The supports are positioned to couple to the centerpiece such that the plates are positioned coplanarly with an upper face of the table. The plates are configured to place a piece of wood for cutting with a blade of the miter saw.

An improved miter saw, including a base, a workbench, a stop plate, a swing arm, a motor, a cutting assembly, and an extension platform. The workbench is rotationally disposed on the base. The swing arm is rotationally disposed on the rear of the workbench. The stop plate is disposed on the rear of the base. The extension platform is disposed on two sides of the base. The upper surface of the extension platform and the supporting surface of the base are in a same plane. The extension platform is movably connected to the base through a guide rod. The extension platform comprises an L-shaped limit block and a recess corresponding to the L-shaped limit block. The L-shaped limit block is adapted to turn over in the recess horizontally or vertically along the length direction of a workpiece mounted on the workbench for cutting.

A sawing apparatus for sawing workpieces of wood or plastic material has an adjustable frame part and a drive motor. A circular saw blade is operatively connected to the drive motor and drivable in rotation by the drive motor about an axis of rotation of the circular saw blade. The circular saw blade is adjustable from a ready position into a working position. The ready position is selected as a function of a position of the adjustable frame part such that the circular saw blade carries out a minimized angular travel as working travel during sawing. The adjustable frame part is adjustable at least in a vertical direction and/or in a horizontal direction transverse to the axis of rotation of the circular saw blade as a function of a cross-section of a workpiece to be sawed.

A miter saw including a base, a turntable pivotably coupled to the base about a miter axis, and a miter angle lock assembly. The miter angle lock assembly includes a clamp biased into engagement with the base when in a clamped position, thereby exerting a clamping force on the base for locking the turntable relative to the base. The miter angle lock assembly further includes an override assembly for maintaining the clamp in a released position relative to the base in which the clamping force is released.

The miter angle lock assembly further includes an override assembly for maintaining the clamp in a released position relative to the base in which the clamping force is released.

A miter saw includes a base, a table disposed on the base and having a top surface extending between a front end and a rear end of the table, a cutting assembly overlying the table, the cutting assembly including a rotatable cutting blade having a peripheral cutting edge, and a motor for driving the cutting blade. The miter saw has at least one guide rail interconnecting the table and the cutting assembly for guiding sliding movement of the cutting assembly over the table between a rear-most position and a forward-most position. A locking assembly is coupled with the cutting assembly for locking the cutting assembly in only one position between the rear-most position and the forward-most position. During a cutting operation, the locking assembly remains coupled with the cutting assembly while the cutting blade moves downwardly for preventing sliding movement of the cutting assembly.

A device for setting the miter angle of a machine tool is disclosed. The device includes a clamping block having at least one slot, and a pivot lever on which the machine tool can be mounted and which is pivotable about a pivot point relative to the clamping block between a minimum and a maximum miter angle. The slot includes at least two stop elements offset relative to one another. A setting mechanism includes a lever element for the selection of a maximum miter angle, where the lever element includes a mating stop element is alignable in such a way corresponding to the rotational alignment of the lever element that the mating stop element is able to strike the respective stop element in accordance with the selected maximum miter angle and by which the pivoting movement of the pivot lever relative to the clamping block can be limited.

A miter saw including a base, a turntable pivotably coupled to the base about a miter axis, and a miter angle detent assembly. The miter angle detent assembly includes an actuator and a bi-stable cam mechanism. The bi-stable cam mechanism is operable to lock the turntable relative to the base at a desired miter angle by depressing the actuator a first instance, and is operable to permit relative movement between the turntable and the base about the miter axis by depressing the actuator a second instance.

A saw with a pivotal guard which can pivot from a first position surrounds at least a portion of the lower edge of the saw blade to a second retracted position where the portion of the lower edge of the saw blade is exposed. A biasing mechanism may be provided for biasing the pivotal guard towards the first position. A pivotal guard actuating mechanism is capable of moving the pivotal guard from the first position to the second retracted position. The pivotal guard actuation mechanism includes a hand lever, a cam mechanism comprising a cam and cam follower connected between the hand lever and the pivotal guard wherein the cam is connected to the pivotal guard and the cam follower is connected to the hand lever.

A fence assembly for miter saw includes a mounting base defining a first abutting surface, and a fence unit mounted at the mounting base in one of first, second and third positions in such a manner that the second abutting surface of the fence unit is disposed co-planar with the first abutting surface of the mounting base when the fence unit is set in the first position; the third abutting surface of the fence unit is disposed in a non-coplanar relationship with the first abutting surface of the mounting base to face toward the same direction when the fence unit is set in the second position; the fourth abutting surface of the fence unit is disposed in a non-coplanar relationship with the first abutting surface of the mounting base to face toward the same direction when the fence unit is set in the third position.
