A scale assembly of a table saw includes front and rear outer slide members at front and rear ends of a slide mechanism respectively; front and rear inner slide members at front and rear ends of a table assembly respectively in which the front inner slide member slides in the front outer slide member and the rear inner slide member slides in the rear outer slide member; a block member secured to a front end of a rip fence assembly and including a channel and a spring biased member; and a lever in the channel and including a trigger, a projection, and first and second recesses in which in a locked position, the spring biased member is biased by a spring to enter the first recess and the projection enters a lengthwise cavity on an outer surface of the front outer slide member.

A self-dust extraction dustless table saw includes a table saw frame, saw table, and saw blade installed to the table saw frame. An upper and a lower blade guards are respectively mounted to upper and lower sides of the saw table, the saw blade is mounted in the upper and lower blade guards, and the lower blade guard includes a lower left and lower-right blade guards. Several interval guide barriers are installed on the inner walls of the lower left and lower right blade guards, and the guide barriers transport the dust to a dust outlet on the side of the lower right blade guard.

The invention relates to apparatus for providing for the powered cutting of a workpiece, typically in the form of a planar or sheet material. The apparatus includes a rotatable blade to cut the workpiece and the blade is mountable such as in a first mode of use to be capable of being held in a fixed position in which the workpiece is moved past the blade, and a second mode of use in which the blade is moved with respect to the workpiece to cut the same. The workpiece is mounted on a base and the blade is mounted with respect to the base via one or more slide members.

A table saw includes a table, a saw unit movably coupled underneath the table, a riving knife extending through the table, and a quick-release assembly selectively coupling the riving knife to the table. The quick-release assembly includes a mounting plate coupled to the table and a clamping plate movable relative to the mounting plate between a clamping position, in which the riving knife is clamped between the mounting plate and the clamping plate to secure the riving knife to the table, and a release position, in which the riving knife is releasable from the table. The quick-release assembly further includes a pin coupled for movement with the clamping plate and a handle pivotably coupled to the pin. The pin has a cam portion engageable with the saw unit. The clamping plate is movable between the clamping position and the release position in response to pivoting movement of the handle.

Inserts for table saws are disclosed. The table inserts are equipped with a toolless locking mechanism that mechanically holds the insert in place and which allows for the installation and removal of the insert without the use of tools. The locking mechanism is easy to lock and unlock and yet robust enough to hold a zero-clearance insert in place.

A fence assembly configured to guide a workpiece with respect to a blade of a saw device includes a fence that is supported by rails for sliding movement relative to a work surface. Opposed ends of the fence are supported on the rails via rail engagement members. The fence assembly includes a fence angle adjustment mechanism associated with a housing of one of the rail engagement members. The fence angle adjustment mechanism includes biasing elements working in conjunction with an adjustment screw to adjust the position of the fence with respect to parallelism to the blade.

A scale assembly of a table saw includes front and rear outer slide members disposed at front and rear ends of a slide mechanism respectively; front and rear inner slide members disposed at front and rear ends of a table assembly respectively wherein the front inner slide member slides in the front outer slide member, and the rear inner slide member slides in the rear outer slide member; a block member secured to a front end of a rip fence assembly and including a channel and a spring biased member; and a lever in the channel and including an exposed trigger, a projection, and first and second recesses. In a locked position, the spring biased member has one end entered the first recess and the projection enters a lengthwise cavity on an outer surface of the front outer slide member.

Blade guards for table saws are disclosed. The blade guards can be used in a configuration where the guard holds a work piece against a work surface. This may be thought of as blade guards with hold-down capability. The blade guards also include splitters and anti-kickback assemblies. The anti-kickback assemblies include anti-kickback pawls that can be in an operable configuration or a disabled configuration.

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.
