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.

The present disclosure relates to a tile or masonry saw assembly comprising a saw device (2) including a motor (5) arranged to run a saw blade (4) to cut a workpiece. The saw assembly also comprises a frame (3) that is arranged to support the saw device (2) and a workpiece support (15) operably coupled to the frame (2) to support the workpiece relative to the saw device (2). The saw assembly further comprises a cover assembly (6) with a cover (9) and a supporting structure (10). A front end (25) is arranged to face the saw blade (4) and an opposing rear end (26) where a dust hose attachment (11) is positioned and arranged to be connected to a vacuum dust collection arrangement. The supporting structure (10) comprises a base (16) that is arranged to be fastened to the workpiece support (15). The cover (9) is movable relative the base (16), and the cover assembly (6) is releasably attachable to the workpiece support (15).

A ring saw includes a ring saw blade, a tool holder that guides the ring saw blade in a cutting plane, a receiving space in which the tool holder is disposed, a motor, and a driving wheel where the ring saw blade is drivable in the cutting plane by the driving wheel and the driving wheel is coupled to the motor. A guide roller is disposed on a side of the cutting plane where the ring saw blade is guidable by the guide roller from the side and where an outlet of a water flushing system is directed at the guide roller.

A suction-extraction adapter for a drilling tool has a housing and a tool connection unit. The housing has a suction-extraction device interface for the detachable connection of a suction-extraction device to the suction-extraction adapter. The tool connection unit enables the axial fixing of the suction-extraction adapter on the drilling tool. The housing also has a locking mechanism. The tool connection unit is configured to be locked on the housing of the suction-extraction adapter via the locking mechanism.

A water collection assembly for a saw blade of tile saw includes, a collecting tray and a wiper blade. The collecting tray includes a collecting tank. The wiper blade is disposed on the collecting tray and is located in the collecting tank. The wiper blade has a notch defined therein which accommodates a part of the saw blade without interfering with the saw blade. Therefore, during the cutting process of the saw blade, the excess water driven by the high-speed rotating saw blade will be scraped off by the wiper blade, and the water will be guided by the wiper blade to the collecting tank. Accordingly, water splashing can be reduced during cutting process.

A spray dust compression system and method includes a nozzle holder for affixing a spray nozzle to a percussive tool. The nozzle holder includes an arcuate wall having a first surface engageable with the percussive tool, and a second surface opposing the first surface. A protruding body protrudes radially outwardly from the second surface relative to a longitudinal axis of the arcuate wall and a concave recess is formed in the protruding body and receives the spray nozzle. The concave recess is angled inwardly toward the longitudinal axis of the arcuate wall.

A worktable for tile cutter with water drainage assembly includes a movable platform and a pivotable guiding member. The movable platform has a drainage channel defined therein. The guiding member has a diversion channel defined therein and communicated with the drainage channel. The guiding member has a first diversion opening and a second diversion opening respectively located on two ends thereof. When the movable platform is in a first position, the first diversion opening is inclined downwards such that the diversion channel guides the water from the drainage channel through the first diversion opening to a water collection tank located under the movable platform. When the movable platform is in a second position, the second diversion opening is inclined downwards such that the diversion channel guides the water from the drainage channel to the water collection tank. Therefore, the draining worktable can provide a good drainage effect.

A cutting belt comprises a guide bar system that includes a guide bar. The guide bar has a first end section, a second end section, and a central section between the first end section and the second end section. A first upper fluid channel is defined through the guide bar. The first upper fluid channel has an entrance opening in the first end section of the guide bar and extends to the central section of the guide bar where it is in fluid communication with a bottom channel. The second upper fluid channel has an entrance opening in the second end section of the guide bar and extends to the central section of the guide bar where it is in fluid communication with the bottom channel.
