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.

A compound saw includes a base, a housing, a transmission component and a table, the rear end of the table is rotatably connected to the housing, and is engaged with the cutter head through the transmission component, so as to expose the cutter head out of the first cutting slit or out of the second cutting slit when the front end of the table swings upward and downward. The cutter head of the compound saw can be switched between the bench cutting mode and the miter cutting mode. Accordingly, on one hand, the structure for switching between modes is simple and does not require the cooperation of too many parts; on the other hand, the switchover can be realized simply by manually operating the movable bench, without too many operations.

A table saw has a base assembly, a table assembly supported by the base assembly, the table assembly, and a saw assembly supported by at least one of the table assembly and the base assembly. The saw assembly has a saw blade extending through the table assembly. The base assembly has at least one foot having a substantially horizontal surface, a substantially vertical surface, and a curved surface disposed between the substantially horizontal surface and the substantially vertical surface. The substantially vertical surface is substantially coplanar with a surface of the table assembly so that the table saw can be disposed on the substantially vertical surface and the surface of the table assembly.

A twin-head bar cutting device includes a first cutting head and a first bar holding device as well as a second cutting head and a second bar holding device placed on a common base. The base includes a first placement surface on which the first cutting head is placed, a second placement surface on which the second cutting head is placed, and a holding device placement surface formed higher than the first placement surface and the second placement surface between the first placement surface and the second placement surface and on which the first bar holding device and the second bar holding device are placed, and the first cutting head and the second cutting head are arranged symmetrically about a vertical plane passing through a center in a width direction of the base.

A multipurpose cutter table comprises a table member having a long hole in which a saw blade is installed; a pair of leg members foldably installed on a bottom surface of the table member and supporting the table member; a pair of side supporting members installed to be adjustable in length on both sides of the table member and to support a cutting object on both sides of the table member; and an upper surface supporting member foldably installed on an upper surface of the table member and installed so that the cutting object is placed on the upper surface of the table member. Accordingly, a cutting object longer than the table member can be stably placed by the side supporting member, the height of the horizontal fixed frame can be freely adjusted, and a huge working space placing a cutting object before and after cutting can be obtained.

A power saw machine for cutting a work piece includes a supporting frame, a cutting blade, and an environment control arrangement which includes a cutting table base, a sliding vacuum hood, and an outlet. The cutting table base is slidably supported by the supporting frame for supporting the work piece. The sliding vacuum hood has a narrow collecting chamber with a continuous inlet for directly contacting with the work piece to omit a spatial gap between the narrow collecting chamber and the work piece, wherein during the cutting process, a cutting portion of the cutting blade is entered into the narrow collecting chamber through the continuous inlet for cutting the work piece. The outlet is provided at the sliding vacuum hood for sucking residual debris of the work piece within the narrow collecting chamber during the cutting process.

A miter saw has a base having a detent notch, a table rotatably connectable to the base, a pivoting assembly connected to the table, and a saw assembly supported by the pivoting assembly. The saw assembly has a blade movable downwardly for a cutting operation. A locking mechanism is disposed on the table. The locking mechanism is movable between an unlocked position and a locked position for selectively unlocking and locking the table for rotational movement relative to the base about the miter axis. The locking mechanism has a lock lever rotatably connected to the table. The lock lever has a handle for moving locking mechanism between the locked and unlocked positions. The saw also has a miter detent assembly for selectively engaging and disengaging the detent notch.

Disclosed is an electric cutting machine comprising: a base (1); a longitudinally movable table (2); a cutting head (3) provided with a cutting disc (32) and an electric drive motor (33); two rolling assemblies (4) with wheels (41) and rolling bearings (43) mounted by means of independent axles (42, 44) on a vertical partition (52) of parallel longitudinal profiles (5) mounted on the base (1); a pair of longitudinal guides (6) attached to the movable table (2) and which comprise a longitudinal support track (63) for supporting on the wheels (41) of the corresponding rolling assembly (4), and a horizontal wing (65) located under the rolling bearings (43) of the corresponding rolling assembly (4); and interchangeable longitudinal guides (6a) longer than the longitudinal guides (6), for adapting the cutting capacity.

A power tool includes a tool housing and a mechanism disposed inside the tool housing. The tool housing has a composite structure that includes an outer layer and an inner layer. The outer layer provides an outer surface of the power tool housing and comprises a first material. The outer layer is an assembly of concave shell portions joined along parting lines. The inner layer is disposed on an inner surface of at least a portion of the outer layer so as to be disposed between the portion of the outer layer and the mechanism. The inner layer comprises a second material. The first material has a density that is at least three times the density of the second material. The inner layer has a peripheral edges that are offset relative to the parting lines such that the inner layer extends continuously across the parting lines.
