Abstract: A lockout mechanism for use with a saw, the lockout mechanism including a lockout actuator, a lever, and a pin. The lockout actuator is movable between a safety position in which the lockout actuator inhibits actuation of a trigger and a use position in which the lockout actuator permits actuation of the trigger. The lever is coupled to and movable with the lockout actuator and the pin. The pin is movable between a first position and a second position. The first and second positions correspond with the safety position and use position, respectively. In the first position, the pin is configured to inhibit a motor housing from being moved from a raised position toward a plunged position. In the second position, the pin is configured to permit the motor housing to be moved from the raised position toward the plunged position.

Abstract: A table saw including a table having a top surface, an opening in the table through which a saw blade extends, and a throat plate receivable within the opening. The throat plate includes a front end that sits flush with the top surface of the table, a back end that sits flush with the top surface of the table, a top surface that is co-planar with the top surface of the table, and a wear plate pocket that is recessed from the top surface of the throat plate. The wear plate pocket defines a bottom surface that is oriented at an oblique angle relative to the top surface of the throat plate and slopes downward in a direction from the back end toward the front end. The wear plate positioned within the wear plate pocket. The wear plate sitting parallel to the bottom surface of the wear plate pocket.

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 table saw includes a frame; a saw having a cutting blade supported by the frame; first and second rails extending along opposite sides of the frame; a table supported by the frame; and a fence extending across the table between the first and second rail. A fence holder removably secures the fence to the first rail. The fence holder has a housing and an alignment arrangement configured to balance opposing forces between the fence holder housing and the first rail to hold the fence in a fixed angle relative to the first and second rails.

Abstract: A circular saw includes a shoe, a shoe plate, a saw unit, and a trim angle adjustment mechanism. The saw unit includes a circular saw blade defining a blade plane, and the saw unit is coupled to the shoe by a shoe plate. The trim angle adjustment mechanism is operable to adjust a trim angle between a trim axis formed at an intersection of the blade plane and the shoe plane and a reference trim axis, the reference trim axis being parallel to a groove in a track along which the circular saw is slidable. The trim angle is adjustable to align the trim axis with the reference trim axis in response to sliding movement of the shoe plate relative to the shoe, the sliding movement caused by adjustment of the trim angle adjustment mechanism.

Abstract: A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly about a first axis. The saw unit includes a saw arm, a motor supported by the saw arm, and a saw blade supported by the saw arm. The saw blade is driven by the motor to rotate about a second axis. The saw blade includes a diameter. A ratio of the diameter of the saw blade to a distance between the first and second axes is between 0.4 and 0.7.

Abstract: A table saw including a table, an opening in the table through which a saw blade extends, and a throat plate receivable within the opening. The throat plate includes a top surface that is co-planar with a top surface of the table. The table saw further includes an anti-kickback pawl disposed above the throat plate and a wear plate coupled to the throat plate in facing relationship with the anti-kickback pawl, where at least a portion of the wear plate is sub-flush with the top surface of the throat plate.
