Abstract: Cutting devices and associated methods are described. In one aspect, a cutting device includes an annular support body defining an axial space into which a pipe to be cut can be inserted, the body formed of a rigid material and including a blade-bearing portion and a non-blade-bearing portion, wherein 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 a pipe can be inserted, and a closed position in which the pipe is engaged by the body, wherein a part of the blade-bearing portion spaced from the hinge mechanism includes a blade that protrudes radially inwards of the 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.

Abstract: An apparatus for machining a tubular piece, wherein the apparatus includes a frame element, support rollers, which are associated with the frame element, support a workpiece and rotate the same around its longitudinal axis. In addition, the frame element is provided with a machining unit adapted to be movable towards and away from the workpiece. The machining unit includes a tool member, such as for example a cutting tool, as well as support wheels adapted to bear against a workpiece. The machining unit is arranged to link up with the frame element through the use of an auxiliary frame element adapted to clamp itself thereto at not less than two support points, for example through the use of a self wedging assembly implemented with an indentation.

Abstract: A cutting tool includes a body, a moving base, and a roller base. The body has a rail groove, whose one side is extended upward with a stopping wall. The moving base is disposed in the rail groove of the body and has a cutting wheel. The moving base is connected with a transmission element and driven by the transmission element to move along the rail groove. The roller base is interposed between the moving base and the stopping wall. There are a plurality of elastic elements between the roller base and the stopping wall. The roller base is disposed with at least two rollers opposite to the cutting wheel.

Abstract: An improved structure of a cutting tool includes a body, a moving base, and a roller base. The body has a track groove whose one side is extended upward with a stopping wall. The moving base is disposed to slide in the track groove and mounted with a cutting wheel. The moving base is connected with a transmission element so as to move along the track groove. The roller base is disposed between the moving base and the stopping wall. More than one elastic element is disposed between the roller base and the stopping wall. The elastic elements generate a deviation when the roller base is under a force. The roller base has at least two rollers corresponding to the cutting wheel.

Abstract: The present invention provides a measuring tool and cutting device for use with metal pipes and tubes. The device provides accurate measurement of a length of pipe and a tool to cut sections thereof. The device comprises a crescent shaped pipe cutter with a measuring portion affixed to its distal end. The measuring portion is a retractable tape measuring device that allows the user to place the cutting tool at a specific distance from an end of the pipe. Once positioned at the desired location, the device grips and secures to the pipe using a scoring blade and two rollers. The measuring tape is then retracted and the user rotates the cutting device around the pipe to score and cut the pipe at that location. The device is small and compact, and may be used in a plurality of situations and locations involving pipes and pipe fitting. It is designed for quick access to a measuring means and for rapidly measuring and scoring sections of pipe.
