Two 18V-type rechargeable batteries (31 and 31) are attached in series so as to allow a 36V-type tabletop cutting device (C1) to be utilized. By utilizing the 18V batteries which are highly prevalent for electric tools, it is possible to use the 36V-type tabletop cutting device (C1) as well as to reduce costs for the batteries.

The present invention pertains to the technical field of shields, and in particular, relates to a stage dedusting shield for a dust-free table saw, comprising: a shield assembly and a dust suction cover assembly; wherein the dust suction cover assembly is mounted between a follower board and a rear portion of a saw blade and is fixed by the follower board and a rear rocker arm. The dust suction cover assembly comprises a dust suction cover and a rear rocker arm sleeved onto the exterior of the dust suction cover, wherein the dust suction cover and the rear rocker arm are movably connected to a dust suction cover torsion spring via a dust suction cover rotary pin.

A cutting device main body with a saw blade in a tabletop cutting device, supported so as to be swingable in an up-to-down direction with respect to a table on which material to be cut is placed, aims to improve operability for attaching and detaching the battery. A sliding direction for attaching and detaching the battery is set to be a tilting direction angled with respect to an up-to-down moving direction of the cutting device main body in a surface direction of a cutting blade. Because of this configuration, all of an operation force for attaching and detaching the battery is not applied to the up-to-down moving direction of the cutting device main body. As a result, the cutting main body is not moved in an easy manner and operability for attaching and detaching the battery is improved.

A bolt assembly (100) enables a user to change a circular blade (160) on a power tool (200) without the use of tools. The bolt assembly includes a bolt body (110) that has a bolt head (132) and a shank (136) that extends axially from the bolt head. The bolt head has a shoulder and the shank has external threads that mate with a threaded bore (220) of a drive shaft (212) of the power tool. A grip body (130) is formed circumferentially around the bolt head to facilitate rotation of the bolt body by the user's hand. An upper washer (114), a needle roller thrust bearing (116), and a lower washer (118) are positioned on the bolt head and retained with a retaining clip (120). The bolt body is rotated to press the lower washer against a clamping surface of the circular blade. The bolt assembly permits rotation of the lower washer relative to the bolt body without rotating the bold body.

A rail system for a power tool has a base defining a work surface for supporting a workpiece, a support mounted to the base, a number of elongated rails slidably supported by the support for movement relative thereto, a yoke engaged to the number of elongated rails for movement with the elongated rails, and a power tool assembly supported by a yoke for performing an operation on the workpiece. A rail stop is movably mounted to one of the support and the yoke, the rail stop including a stop surface adapted to abut the other of the support and the yoke when the rail stop is in a first position between the yoke and the support. The rail stop is movable to a second position different from the first position.

A miter saw includes a base assembly, a bevel arm pivotably coupled to the base assembly, and a saw unit pivotably coupled to the bevel arm about a horizontal chop axis. The saw unit includes a saw blade rotatable about a blade axis and a motor having an output shaft inclined at an oblique included angle relative to the blade axis. The miter saw also includes a guide rail coupling the saw unit to the base assembly and a battery selectively electrically connectable with the motor to provide power to the motor. The bevel arm and saw unit are pivotable relative to the base assembly, from an orientation in which the saw blade is substantially vertical, in both a first direction about the bevel axis by a bevel angle of at least about 45 degrees and an opposite, second direction by a bevel angle of at least about 45 degrees.

A miter saw has a base assembly and a rotatable table disposed on the base assembly. The rotatable table is rotatable about a substantially vertical miter axis and has a substantially horizontal workpiece-supporting plane. A saw assembly is connected to the table and includes a blade. The blade is movable downwardly from a first position where the blade is above the workpiece-supporting plane to a second position where a portion of the blade is below the workpiece-supporting plane. The base assembly has a top surface and a first handle disposed on the top surface, with a first hole on the top surface extending through the base assembly, the first hole being configured to allow a user to extend the user's hand therethrough and grip the first handle.
