A modification system for the modification of elongated pieces of stock may include a powered tool for modifying, or altering the piece of elongated stock, and a support device for supporting a position of the elongated stock relative to the powered tool. An arrangement of the components of the powered tool may provide for ergonomic balance of the powered tool. The support device may include a clamping device that clamps, or holds the elongated stock, and an adjustment device that adjusts a position of the clamping device based on a size of the elongated stock. The support device may include a latching device that maintains the position of the clamping device relative to the stock. A reaction arm may inhibit rotation of the tool relative to the stock during operation. A biasing device may provide for application of an axial biasing force on the stock, to initiate operation.

A method for centering device on a cutting device using an ultrahigh pressure (UHP) hose carrying UHP fluid that is designed to be inserted into a pipe or tube and cut the same from the inside out. In one example, the cutting device is for insertion into a wellbore for cutting the casing of the wellbore from within the wellbore with a revolvable UHP hose. The cutting head which effectuates the cut may be centered by the centering device that is generally conical in shape such that a portion of the centering device remains exterior to the pipe or tube as the UHP revolves during the cutting action.

Power drive tools are described. The tools include one or more threading pawls, one or more release pawls, and a drive ring selectively positionable relative to the tool and engaged with the pawls to selectively extend or retract the pawls. Also described are tools that include one or more lights to illuminate a workpiece. Also described are tools having distally located shoulder regions at which force may readily be applied. In addition, gear train assemblies for use in the power drive tools are described.

A power tool for forming threads includes a tool housing with a motor housing portion having a first handle, a battery receptacle configured to receive a battery, a motor housing portion with a motor, a transmission housing portion with a transmission, and an operating head portion arranged along a tool axis. A cutting head is at least partially received in the operating head portion and rotates about a rotational axis transverse to the tool axis to form threads in a workpiece. A second handle is coupled to the operating head or the tool housing adjacent the operating head. When power is applied to the motor, the motor rotates and the transmission transmits torque from the motor to rotate the cutting head. A center of gravity of the power tool is positioned at a portion of the tool housing substantially aligned with the second handle.

A refacing tool includes a feed assembly that holds a first set of cutters positioned for refacing the inner shoulder of a pin or box end of a tubular and a second set of cutters positioned for refacing the outer shoulder of the pin or box end. The axial spacing between the first set of cutters and the second set of cutters is fixed and determined by the geometry of the feed assembly. The refacing tool can simultaneously reface the inner shoulder and the outer shoulder, as well as chamfers.

A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand upon which at least one pipe threading tool is supported, a spindle including a plurality of chuck jaws for clamping the pipe, the chuck jaws configured to move radially inward along a travel path toward an outer surface of the pipe, and a sensor system configured to determine a location of the chuck jaws along the travel path and relative to the outer surface of the pipe, the sensor system configured to output a signal corresponding to the location of each of the chuck jaws when engaged with the outer surface of the pipe. The portable pipe threader further includes an electronic controller in communication with the sensor system configured to determine an outer diameter of the pipe in response to the signal output from the sensor system.

The whirling device comprises a retaining ring extending around a ring axis and a central opening and having at least one receiving area for a machining element for machining rod-shaped material in the area of the central opening. A coolant supply comprises a supply sleeve which is arranged on the retaining ring via a rotary bearing and comprises a coolant connection and a supply area adjoining a connection area of the retaining ring. Starting from at least one inlet opening in the connection area of the retaining ring, at least one passage leads through the retaining ring to at least one outlet opening which faces the central opening of the retaining ring and is designed for a machining element in a receiving area. No space is required for the coolant supply between the retaining ring and an assigned lathe.
