ABSTRACT:
A metal pipe bevelling tool has a shaft with a forward end portion on which is mounted a mandrel with movable jaws engageable with the inside of a pipe end to hold the shaft coaxial with the pipe. A tool hub is rotatably supported by a rearward end portion of the shaft, the tool hub carrying cutting tools for bevelling the end of the pipe, and also having means engageable with an auxiliary power drive for rotating the tool hub. The tool hub, and consequently the whole apparatus, is enabled to be fairly small and light by a special mounting arrangement for the cutting tools. In this arrangement, the tool hub has recesses the axes of which lie in a direction extending outwardly and forwardly from the hub, and these recesses are each provided with a tool holding sleeve having an external surface fitting closely within the respective recess and defining a central cavity of square cross section for receiving the shank of a cutting tool. The tool is mounted so that its cutting portion extends beyond the outer end of the sleeve, and the sleeves themselves project outwardly beyond the hub so that the hub can be much smaller than the pipe to be bevelled, while the sleeves still provide adequate support for the cutting tools.
