ABSTRACT:
A portable, hand-held bevelling device for providing a bevel on both the exterior and an interior of a tube comprises a housing having an interior and an upper extended portion and a lower extended portion. The upper extended portion is spaced a distance away from the lower extended portion for defining a space. A hydraulic clamp is located on the exterior of the housing and comprises an upper clamp portion provided on the upper extended portion of the housing and a lower clamp portion provided on the lower extended portion of the housing for hydraulically clamping a tube. A bevelling head having cutters for providing the interior and external bevels on the tube is contained within the interior of the housing and is extendable through the space between the upper extended portion and the lower extended portion toward the exterior clamp. The bevelling head is connected to a movable shaft located within the housing wherein both the head and the shaft are rotated by an air motor and a drive belt. The shaft and head are extended within the housing through bearings and a gear box which is openly controlled by a hand-operated feed wheel located at an exterior of the housing.
