Power tools such as cutting saws with rotary powered blades are described. Also described are various accessories for tools used with cylindrical workpieces such as pipes are described. The accessories include a clamp and saw joint assembly, various quick connection assemblies between a saw and a clamping system, a plunge guide assembly, a latch plate assembly, an interlock switch, a blade guard system, and a chip management system or chip deflector. Also described are related methods of use.

According to an aspect of the present disclosure, a low profile travelling pipe cutter is provided which is adapted to perform at least one of cutting and beveling a hollow vessel while traveling around the vessel using a cutting tool mounted thereon. The pipe cutter includes inner and outer carriages, a capstan assembly attached to the outer carriage to which a feed cable is attached, and rollers attached to the outer carriage to which a tension cable is attached. The force adjustment assembly changes the vertical position of the outer carriage relative to the inner carriage to compensate for the pipe cutter going inwardly and outwardly as it travels around a hollow vessel in order to maintain constant pressure caused by the lever tension interface. A guard assembly is provided for covering and uncovering the cutting tool during cutting.

A cutting device for cutting a pipe of a set diameter comprises an annular support body defining an axial space into which a pipe to be cut can be inserted. The annular support body is formed of a rigid material and comprises a blade-bearing portion and a non-blade-bearing portion. The blade-bearing portion is secured to the non-blade-bearing portion by a hinge mechanism allowing the two portions to be movable between an open position, in which the pipe can be inserted and removed from the body, and a closed position, in which the pipe, once inserted, is engaged by and axially aligned with the annular support body. A part of the blade-bearing portion spaced from the hinge mechanism comprises a blade that protrudes radially inwards of the annular body, such that in use the urging of the two portions towards the closed position urges the pipe against the blade so that rotation of the cutting device around the pipe cuts the pipe.

The accessories include a clamp and saw joint assembly, various quick connection assemblies between a saw and a clamping system, a plunge guide assembly, a latch plate assembly, an interlock switch, a blade guard system, and a chip management system or chip deflector. Also described are related methods of use.

Coupling members and pipe machining apparatuses including coupling members are provided. In one aspect, a coupling member includes a shaft and an engagement member defining a cavity there through and including a projection. The shaft is at least partially positioned within the cavity and extends through the cavity, and the shaft is adapted to rotate relative to the engagement member. The coupling member also includes a plunger at least partially positioned within the cavity and movable relative to the engagement member, and further includes a biasing member at least partially positioned within the cavity between the plunger and the engagement member.

A pile cutter, suitable for cutting of steel reinforced concrete piles, has a frame with a pile receiving area and a generally U-shaped track around the pile receiving area. A single saw blade, for example a diamond tipped rotary saw blade, is carried on a saw blade carriage assembly, which is movably mounted on the U-shaped track. The dimensions of the various components are such that the saw blade cuts past a center line through the pile receiving area. By moving the saw blade carriage assembly first to one end of the U-shaped track, then to the other end, the pile can be completely severed.

A pipe cutting apparatus has a rigid annular frame adapted to be coupled to a pipe to be cut. A cutting blade for cutting the pipe is removably associated with the annular frame. A mechanism is included to move the cutting blade with respect to the annular frame about an axis of revolution designed to coincide with a longitudinal axis of the pipe.
