ABSTRACT:
An attachment for mounting a power tool, such as a hand drill or a router, having a cutter to enable the tool to be used to bevel the outside surface of hollow pipes. The attachment is capable of mounting a variety of different power tools and is adjustable to enable beveling the ends of pipes having different diameters. The device includes a base plate that mounts the power tool to one side thereof. The plate has an opening through which the rotary cutter projects forwardly. Also, projecting forwardly of the face plate are three freely rotatable guide rollers. The various elements are relatively adjustable in the plane of the face plate to accommodate pipes of different diameter. One of the rollers is utilized to engage the inside surface or core of a pipe end portion while the remaining two rollers engage the outside surface of the pipe at opposite sides of the rotary cutter. The pipe walls are movably guided between the three rollers with the rotary cutter engaged against the outside pipe surface at the pipe end. In operation, the device may be rolled about the pipe circumference as the rotary cutter forms the desired bevel, or the pipe itself may be turned about its center axis while the attachment is held stationary.
