摘要： A portable circular saw includes a base. A saw blade has a portion projecting downward from the base. A saw-blade cover conceals at least a part of the saw blade. A projection provided on the saw-blade cover protrudes in a direction away from the saw blade. The projection has a lower surface extending across a first plane which is parallel to an axis of rotation of the saw blade, and which contains a tangent to an outer circumference of the saw-blade at a point of intersection with a second plane including a lower surface of the base. Chips fly from the point of intersection along a direction in the first plane. The lower surface of the projection inclines relative to a line perpendicular to the tangent so as to change a path of a portion of flow of the chips toward a forward side as viewed in a cutting direction.

摘要： A portable electrical tool includes a tip tool; a cylindrical housing accommodating a motor including a chuck attachably and detachably holding the tip tool at tip end of a rotation shaft; a base including a surface plate which slides on an upper surface of work material, and which allows the tip tool to protrude from the surface plate downwardly, a cylindrical portion including a cutout portion, and a lever having a cam surface, and rotatable to a fixed position and a release position. When the lever is in the fixed position, a gap at the cutout portion is narrowed to stop movement of the cylindrical housing. When the lever is in the release position, the cylindrical housing is movable by weight in the cylindrical portion. The tool includes a stopper to stop a rotation of the lever between the fixed position and the release position.

摘要： A laser emitter projects a planer light beam to form an optical guideline on a work piece extending in a cutting direction of saw blade. The laser emitter is arranged behind, in the cutting direction, a tangential line of the circumference of the saw blade at an intersection of a bottom surface of the base and the circumference at a front side of the base in the cutting direction. The laser emitter forms the optical guideline behind the intersection in the cutting direction. The laser emitter is supported in respect of the saw blade slidingly in a direction defined by a rotation axis of the saw blade. The saw cover may have a window to transmit the laser beam toward the cutting point. A shutter selectively shutting the window may be provided.

摘要： A portable circular saw device having sawdust discharge arrangement which prevents sawducts from being discharged toward an operator. The circular saw has an upper blade guard which has one side wall and an opposite side wall, and a discharge opening is formed at the one side wall for discharging, through the discharge opening the sawdusts laterally away from the operator. For further ensuring this lateral discharge of the sawdusts, a deflector is provided at the one side wall at a position close to an upstream edge of the discharge opening. The deflector protrudes from an inner surface of the one side wall toward the opposite wall for directing the sawducts passing along the inner surface of the one side wall toward an end portion on which the sawducts are reflected and are then directed to a direction perpendicular to the moving locus of the sawdusts.
