ABSTRACT:
A portable single-point beveling tool includes a tool housing, an associated tool drive mechanism and a base member which is rotatably supported on the housing for rotary motion about a rotation axis and arranged to be rotated by the tool drive mechanism. The base member has a portion which extends in a generally radial direction with respect to the rotation axis. The base member carries a cutting tool holder assembly, which includes a cutting tool holder. The base member also carries a cutting tool feed assembly, which is arranged to simultaneously drive the cutting tool holder assembly in a linear radial direction and the cutting tool holder in a linear axial direction with respect to the rotation axis. Rotary motion of the base member actuates the cutting tool feed assembly to drive the cutting tool holder assembly and the cutting tool holder.
