The invention refers to a mandrel holder for a pipe cutter having a nearly C-shaped bracket, which supports counter-pressure rollers on one end and is connected, at the other end, to a longitudinal handle containing an adjustment device carrying a cutting wheel, these components defining a tool plane through which a vertical axis passes, which extends between and axially parallel to the counter-pressure rollers and the cutting wheel. The tool plane contains the cutting point of the cutting wheel. The mandrel holder contains a coupling portion designed to radially and axially encompass an arc-shaped portion of the C-shaped bracket, an outer longitudinal portion extending from the coupling portion axially parallel to the vertical axis up to an end piece, and an inner longitudinal portion which extends from the end piece along the vertical axis back approximately to the tool plane and has a rotatable mandrel.

A powered cutting tool for cutting tubular or cylindrical workpieces such as pipe is described. The cutting tool includes a base, an electric motor, a collection of rollers, a frame, a feedscrew, an auto cut wheel system, and a handle for rotating the feedscrew and adjusting the position of the auto cut wheel system relative to the rollers. In certain versions, the cutting tool includes torque-limiting provisions, to limit the amount of torque applied to the feedscrew. In certain versions, the cutting tool includes rollers and press wheels featuring non-metal outer surfaces.

A cutter, such as a tubing cutter or a swing cutter. The cutter may include a cutting wheel; a roller; a housing assembly including a first housing portion supporting the cutting wheel and a second housing portion supporting the roller; a shaft connecting the housing portions, rotation of the shaft causing relative movement of the housing portions along a shaft axis; and a knob connected to the shaft and engageable by a user to rotate the shaft, the knob having, in a plane perpendicular to the shaft axis, a non-symmetrical shape defined by opposite circular sector portions and opposite lever portions, each lever portion being engageable by a user to apply a force to the knob in a direction of rotation. The cutter may include a shaft with a radial shoulder preventing movement of the shaft from the cavity through an opening in the housing portion.

The invention relates to a tube cutter (1:1.1) for cutting a round tube (100). The tube cutter (1:1.1) comprises a main body (2:2.1), a cutting device (3) assigned to the main body (2:2.1), and a rotary guide (4) for the main body (2:2.1). The rotary guide (4) is designed to rotatably receive the round tube (100) in order to allow for a rotation of the tube cutter (1:1.1) about the central axis (110) of the round tube (100) along its outer circumference (120). The cutting device (3) has a cutting part (5) with a blade (6) lying in a cutting plane (7) and is designed such that, with a rotation of the tube cutter (1:1.1) about the round tube (100), the blade (6) executes a circumferential cut (400) in the cutting plane (7). In the tube cutter (1:1.1), at least one forming element (8) is also provided, which protrudes into the cutting plane (7) or is positioned at least in the cutting plane (7) and is designed such that, with the rotation of the tube cutter (1:1.1) about the round tube (100), it acts in a forming manner on the outer circumference (120) of the round tube (100), in order to form a bevel (131; 141) at an end of at least one of the tube parts (130, 140), created by the cut (400) of the blade (6), by means of material displacement. The invention also relates to a method for cutting a round tube (100) to length.

A power tool accessory for cutting tubular members includes a housing, an input shaft configured to be coupled to a rotary power tool, a transmission, and a cutting head removably received in a front end of the housing. The transmission includes an input gear and an output gear with a first plurality of teeth. The cutting head has a central opening, a cutting blade protruding into the central opening, and a second plurality of teeth engaged by the first plurality of teeth. A clamp assembly coupled to the housing is moveable between a first position where the cutting head is removable from the housing and a second position where the cutting head is retained in the housing. The cutting head receives a tubular member in the central opening with the cutting blade engaging the tubular member to cut the tubular member as the cutting head rotates about the tubular member.
