Abstract: The invention relates to a device (10) for the at least partial removal of the outside circumferential surface of a pipe consisting of plastic, comprising a hollow cylindrical housing (12), with a wall that surrounds a cylindrical interior space that accommodates the body in an axially moveable manner, at least one opening in the wall as well as a cutting element (74) that is associated with the opening (62) and with its cutting section projects into the interior space. To be able to remove the outside circumferential surface of the pipe in an unproblematic manner and to the desired degree, it is suggested that the cutting element (74) in a front view exhibit a disc or ring geometry and be connected to the housing (12) by a fastening element that extends in the direction of the longitudinal axis of the cutting element, whereby the cutting element can be connected to the housing in the desired position by rotating it about its longitudinal axis.

Abstract: A outer diameter shaft reducer tool includes a cutter head and main body capable of assembly together through the use of a pair of set screws. The assembly can then easily be connected to a hand-held drill through a common extension thereby allowing for the provision of automated rotation of the cutting assembly. To reduce the outside diameter of a shaft, a user inserts the bar or rod into a lumen within the main body and applies pressure to cause a number of cutting teeth to engage the end portion of the bar or rod near the outer portion of the end face. As the teeth cut, the outside diameter of the shaft is thereby reduced.

Abstract: A piling planing tool utilizes a cylindrical cutter head connected to a cylindrical cutter ring having teeth for planing the outer surfaces of damaged or deteriorating in situ pilings. Spacer rings are attached between the cutter head and cutter ring to lengthen the planing tool, in order to extend the tool to plane lower outer surfaces of the pilings. A drill bit extends through the planing tool to bore center channels into the pilings. A circular cutting blade is provided beneath the cutter head to plane the top of the piling. The method of reforming in situ pilings utilizes the planing tool to shape pilings so that they can be connected with new pilings. The pilings are connected by an internal steel rebar and sleeve, permanently secured with bonding material to form a single reformed piling having high tensile strength.

The base section has one or more openings and one or more front-cutting edges located on the trailing side of the openings. When the pipe-end section is further inserted into the inner space of the cylindrical section, the front-cutting edges shave off the front part of the pipe-end section.

Abstract: A jig for cutting plugs for pocket holes from a workpiece has a base leg, from which transversely extend guide and clamp legs. One or more guide channels extend through the guide leg at an angle to an interior face of the guide leg to guide the sleeve of a rotating cutter bit that has a cutting edge at its end and a removed section forming a cutting blade. A clamp extends from the clamp leg to engage one face of a workpiece whose end is mounted on a raised ledge on the base leg and holds the workpiece opposing face against the guide leg interior surface as the sleeve end cutting edge and blade advances into and cuts entirely through the workpiece to cut the plug. A collar on the cutting bit shaft engages the guide leg to prevent the sleeve end cutting edge from contacting the base leg. The jig also can be used for making pocket holes by using the appropriate drill bit.

Abstract: Although useful in many industrial applications for wood, plastic or non-ferrous metals, this original form of this concept is tailored to the wood I-joist industry. One of the benefits of using wooden I-joist construction versus conventional sawn lumber joists is the ability of cutting holes for duct work and other mechanicals to pass through the system. For this to occur in an industrial environment extreme requirements must be met. The cutting rate for a production machine of this type must be unusually fast for hole saw operations. The size of hole cut is necessarily quite large. Combined with an extreme cutting rate this produces unusually large torque and fatigue requirements. Because manual extraction of the cut material would be cumbersome and consume excessive time, a means of automatic ejection of the “divot” is required. With the varying depth and width of beams to be processed comes the need for simple, quick and accurate adjustment to the machine and multiple or variable cutting diameters.
