A cut-off tool includes a housing, an arbor supported by the housing for relative movement therewith, and a cutting disk attachable to the arbor. The cut-off tool further includes a motor coupled to the arbor to provide torque thereto, and a battery pack removably coupled to the housing. The battery pack is for providing power to the motor. The cut-off tool further includes a switch operable to adjust rotation of the motor between a first rotational direction and an opposite, second direction for selectively rotating the cutting disk in the first rotational direction or second rotational direction, respectively.

The present invention is an attachable rolling plate assembly which can be attached as a single unit to a portable cutting tool to facilitate the safe rolling movement of the portable cutting tool on the workpiece. The invention comprises a frame assembly formed from a single piece of molded material such as fiber enriched high-impact nylon having a pair of oppositely disposed longitudinal sidewalls with damping strips extending therefrom, and a flat base portion having an opening through which a saw blade of a power saw extends. The plate has front and rear fastening members to retain a plate of a power cutting saw onto the rolling plate assembly. The invention also includes a cutting guide assembly to facilitate a straight cut, reduce torsional rotation of the saw blade and reduce kickback of the saw.

An elongated bar support device, such as which can be used in singular fashion with an elongated beam or in paired fashion with a flattened sheet board material. An elongated body has a main extending section for supporting an underside of the board or beam. An intermediate section includes a multi-angled recess which extends below the support surface. A forward most portion of each bar support extends in angled or sloping fashion relative to a horizontal extending axis associated with the main extending section. A pair of support dowels extend in linearly spaced apart and inward (cross directed) fashion from the forward extending portion of each bar, to contact opposite surfaces of the plywood or sheet board at support locations forward of the intermediate crosswise recess and opposite a rearward extending direction of the main support section. Upon widthwise sectioning, the opposite surface supporting dowels retain the incised portion in position, without bending or buckling.

To provide a cutting machine that suppresses swinging of the cutting portion when the battery pack is attached or detached, the cutting machine includes a cutting portion, a base, and a swing support mechanism. The cutting portion includes: a motor, a motor housing accommodating the motor, an output shaft configured to be rotated upon rotation of the motor, a battery pack serving as a power source of the motor, and a battery pack attaching portion including a pair of rail portions with which the battery pack is engageable, where a cutting blade is configured to be detachably attached to the output shaft. The base has a contact surface on which a workpiece is configured to be placed. The swing support mechanism is connected to the base and the cutting portion and includes a swing shaft extending in parallel to the output shaft. The swing support mechanism supporting the cutting portion such that the cutting portion is swingable about the swing shaft between a top dead center and a bottom dead center in a direction parallel to a side surface of the cutting blade. The pair of rail portions extend in a direction crossing the side surface of the cutting blade.

There is provided an electric power tool having a plurality of operation modes with different rotation speeds at least in a predetermined load range. The electric power tool is capable of switching between the operation modes when a predetermined condition is satisfied even during a motor is driven, and configured such that a rotation speed of the motor is changed smoothly or in a stepwise manner at the switching between the operation modes.
