Various dust collection apparatuses are disclosed. In a first example, a dust collection apparatus includes a vacuum source configured to provide a negative pressure, and a multistage filter configured to collect airborne dust drawn by the negative pressure. For this example, the dust collection apparatus includes a dust tray having a shared dust containment area in which the shared dust containment area is a single compartment configured to receive the airborne dust collected by the multistage filter directly from each of a plurality of stages of the multistage filter. In another example, a dust collection apparatus includes a filter, a filter housing configured to house the filter, and an inlet coupled to the filter housing. For this example, the inlet is configured to receive a flow of airborne dust drawn by a negative pressure, and is further configured to mitigate an impact of the airborne dust on the filter.

The second beam (201) is adapted to slide on the lateral support structures (16, 18) via its ends (221, 241) and guiding means (26) provided on the lateral support structures (16, 18), independently of the first beam (20). The second beam (201) is provided with a second carriage (281) which is adapted to be moved along the second beam (201). A second sleeve (301) adapted to be moved towards or away from the workpiece support bench (14) is provided on the second carriage (281). A second machining head (321) comprising a second cutting spindle (341) is provided on the second sleeve (301). At least either one of the first head (32) and the second head (321) is provided with a gripping device (42, 421) for the slabs or parts thereof.

Systems and methods for a table-mounted stand that houses a hand-held masonry cut-off saw. In some embodiments, the stand provides a fixed mount that keeps the saw stationary while the operator is allowed to feed the work piece through the saw with both hands. In some embodiments, the stand is configured to mount and un-mount the saw without the need for separate tools or time-consuming restraints. In some embodiments, the stand includes a throttle control that is activated via foot control, which allows for two-hand manipulation of the work piece being cut by the saw mounted on the stand. In some embodiments, the two-handed work-piece manipulation provided by the stand allows for precise curved and multi-angled cuts. In some embodiments, the stand is made of lightweight construction (e.g., aluminum) for ease of setup and mobilization.

A foldable water tray used in a tile cutter includes a water tank having a water chamber, a first tray movable in and out of the water chamber of the water tank between an application position and a storage position, and a second tray pivotally connected to the first tray and biasable relative to the first tray between an extended position where the second tray defines with the first tray a predetermined contained angle and a collapsed position where the second tray covers the first tray and can be moved with the first tray between the application position and the storage position.

A tile saw includes a saw with a cutting blade, a frame supporting the saw, a table supporting a workpiece and being slidable relative to the frame, and a rear fence secured to the table. The rear fence has an engagement surface and is adjustable between an operating position and a bypassed position. The bypassed position includes the engagement surface of the fence being no higher than even with the planar surface of the table to allow a workpiece to extend beyond a rear edge of the table. In the operating position, the engagement surface of the rear fence projects axially from the planar surface of the table to support the workpiece as the workpiece is pushed into the cutting blade during operation. The fence can be adjusted between the operating and bypassed positions by using any one of a cam lever clamp, pin and guideway, or rotatable latch.

Provided is a cutting tool that includes a cutting head, a frame, a working table, a guiding rail assembly, and a fence. The cutting head is configured to perform a cutting function. The frame is configured to support the cutting head. The working table is configured to place an object to be cut. The guiding rail assembly is configured to enable the working table to slide along a first straight line relative to the frame. The fence is mounted to the working table, includes at least one fence surface extending in a direction perpendicular to the first straight line. The cutting tool enables a workpiece to be cut to be stably placed on the working table during a cutting operation.

A tile saw comprising a base, a table supported by the base and configured to support a workpiece, a guide rail upon which the table is supported and moveable along a longitudinal axis, a saw unit coupled to the base, and a roller assembly for supporting the table upon the guide rail. The roller assembly includes a first roller rotatably supported by the table and engaged with a first portion of the guide rail, and a second roller rotatably supported by the table and engaged with a second portion of the guide rail that is different than the first portion. The second roller is translatable relative to the table in a direction toward the guide rail. The roller assembly further includes a spring biasing the second roller toward the guide rail.

The present invention is an all-in-one pavement cutting and debris removal system, which comprises a cutting assembly including a saw blade and motor for supporting and rotating the saw blade, a water supply assembly that sends water to the saw blade including a water tank and water tube to keep the saw blade cool during cutting, and an assembly for removing the cutting debris/slurry created during the cutting. The assembly may utilize a high-pressure air flow or water to blow away the cement/water debris or a high vacuum suction device to vacuum away the cement/water debris. The present system employs a single truck to carry or tow the cutting assembly, water tank and air compressor for the same function that currently requires two trucks.

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.
