A tile saw includes a base, a frame assembly disposed on the base, a first rail disposed on the frame assembly, the first rail having a longitudinal axis. A table is slidingly disposed on the first rail and a support assembly is disposed on the base. A fence assembly is attachable to the table and has a first fence and a second fence for contacting the workpiece. The second fence is pivotably attached to the first fence and pivotable about a substantially horizontal axis. A saw assembly is supported by the support assembly and includes a motor, and a cutting wheel driven by the motor.

A tile or masonry saw assembly may include a saw and a frame. The saw includes a motor operable to turn a blade of a blade assembly to cut a workpiece. The blade assembly is internally wetted during operation by nozzles disposed on opposing sides of the blade to provide water onto the blade within a blade guard configured to shield a portion of the blade. The frame is operably coupled to the saw to support the workpiece. The frame supports a water collecting system for collecting the water. The water collecting system includes a water tank that is removable from the frame.

A tile cutter includes a base, and a cutting head assembly including a supporting arm having one end pivotally connected to the base and an opposite end connected to the saw base for enabling the cutting head assembly to be biased relative to the base and selectively positioned in a standby position, a cutting position or a received position. When shifting the cutting head assembly from the standby position to the cutting position, the supporting arm is received by a stopper to limit the cutting depth of the cutting head assembly. When shifting the cutting head assembly from the cutting position to the received position, the stopper is moved to release the supporting arm. When the cutting head assembly is shifted to the received position, a part of the saw base and the saw blade are received in a sink in the base.

A tile saw includes a base, a frame assembly disposed on the base, a first rail disposed on the frame assembly, the first rail having a longitudinal axis, a table slidingly disposed on the first rail, a support assembly disposed on the base, a saw assembly supported by the support assembly, the saw assembly having a motor, a cutting wheel driven by the motor, the saw assembly being pivotable about a horizontal axis substantially parallel to the longitudinal axis, and a switch electrically connected to the motor and disposed on the support assembly so that, when the motor assembly is pivoted about the horizontal axis, the switch remains stationary.

Various dust collection apparatuses are disclosed, which include a vacuum source, a circular saw blade, and a worktable comprising a center slot axially aligned to the circular saw blade. In a first aspect, the center slot includes an air flow channel proximate to an anticipated point of contact between the circular saw blade and a workpiece, and the vacuum source is configured to provide a focused negative pressure beneath the worktable via the air flow channel In another aspect, the vacuum source provides a negative pressure beneath the worktable at the center slot, and a multistage filter is included to collect airborne dust drawn by the negative pressure from an area proximate to the center slot. In yet another aspect, the vacuum source is configured to provide a first negative pressure beneath the worktable at the center slot, and a second negative pressure via an auxiliary port.

A working head for a cutting machine having a frame, and a cutting disc assembly supported by the frame. The cutting disc assembly having a cutting disc and a first driver rotatably moving the cutting disc around an axis of rotation of the cutting disc. A milling cutter assembly is supported by the frame. The milling cutter assembly has a milling cutter and a second driver that rotatably moves the cutting disc around an axis of rotation of the cutter.
