A concrete saw is disclosed and includes a frame having a platform and a leg pivotably coupled to the platform at a pivot axis, at least two rear wheels coupled to the platform at the pivot axis, at least one rear wheel coupled to an end of the leg distanced from the pivot axis, a power and drive assembly disposed on the platform, wherein the power and drive assembly includes an electric motor and a battery pack coupled to the electric motor to provide direct current power to the electric motor, and a cutting assembly driven by the power and drive assembly to cut a groove in a work surface as the concrete saw is moved across the work surface.

Embodiments include a vehicle side washer assembly, a shaft assembly, and horizontal cloth brush panels. The side washer assembly includes a retractable angled primary arm, a retractable secondary arm, a shaft assembly having an upright shaft, and horizontal cloth brush panels. The upright shaft is disposed through a shaft attachment region of each of the horizontal cloth brush panels. The shaft assembly includes an upright shaft including notches and protrusions, and retrofit discs each including a shaft opening that matches contours of the upright shaft. Each of the retrofit discs includes rotary notches. The horizontal cloth brush panels each include flat fingers, a contiguous central region, and a brush shaft opening cut to match contours of the upright shaft. The horizontal cloth brush panels rotate in a reverse rotation with a direction of travel of a vehicle, and can be mixed and matches with various sizes and shapes.

A cutting grinder for cutting through a rail of a track includes a detection device for detecting a proposed cutting position. The cutting grinder guarantees simple, user-friendly and efficient through-cutting of the rail.

A power tool used to perform a coping cut including a main housing, a motor disposed within the main housing, a drive shaft driven by the motor about a rotational axis, a handle extending from the main housing, and an abrasive disc coupled to and driven by the drive shaft about the rotational axis. The motor is an outer rotor brushless direct current motor capable of rotating at 4,000 surface feet per minute at 1.5 inch-pounds of torque.

The invention relates to a panel saw (1) for cutting plate-shaped workpieces (2) into multiple sections, comprising: a machine base frame (3); a workpiece support (4) with a sawing slot (5); a saw aggregate (7), which is arranged below the workpiece support (4), wherein a circular saw blade (6) is arranged on the saw aggregate (7), which circular saw blade (6) in a sawing position (34) protrudes through the sawing slot (5) and is displaceable in a sawing direction (8); a holding-down device (9) for clamping the workpiece (2) on the workpiece support (4); a positioning device (12) for positioning the workpiece (2).

A machine-tool system, particularly for work on a railway line, having at least one machine-tool such as an abrasive rail saw, and a device for driving the machine. The machine-tool is provided with an electric motor powered by an electric battery which is advantageously arranged in an assembly that can be worn by the operator of the machine and is connected to the motor by a power discharge cable.

A power tool includes a housing, a trigger, a motor supported within the housing, a saw blade interconnected to the housing by a support arm and drivably coupled to the motor, a main handle integrally formed with the housing, an auxiliary handle coupled to the housing and disposed between the saw blade and the main handle, and a battery receptacle defined by the housing and positioned beneath the main handle. The battery receptacle is configured to receive a battery pack to supply electrical current to the motor. The power tool further includes a splash guard integrally formed with the housing and positioned between the battery receptacle and the saw blade.

A cold saw module may be a rail saw module that includes a cold saw configured to cut a railway rail along a cutting path, a rail alignment clamp configured to grip the railway rail near the cutting path, a feed actuator to drive the cold saw along the cutting path, and a module coupling element configured to selectively couple to a mating module coupling element of an articulated arm and/or a tool adapter. Cold saw modules may be used to cut metal workpieces such as a railway rail. Cutting a railway rail may include positioning the cold saw module at a cutting site along the railway rail installed in a railway, clamping the cold saw module to the railway rail, and cutting the railway rail at the cutting site with the cold saw module while the cold saw module is clamped to the cutting site.

A blade storage array is detachably mountable with a tissue log cutting saw. The saw has a cutting arm with a tool holder receptacle adapted and configured to hold a circular saw blade for the saw. The array has a plurality of storage units. Each storage unit is adapted and configured to store a circular saw blade for the saw. Each storage unit has a tool holder receptacle adapted and configured to hold a circular saw blade. Each storage unit is adapted and configured to move perpendicularly to the saw blade center axis.
