A compact, low-profile, in-line beveling tool suitable for use in a confin ed space, such as a tightly packed array of tubes. The tool is inserted within a workpiece via a feeding mechanism, such as a worm gear arrangement, and is secured to the workpiece via an internal expanding mandrel assembly. A motor drives cutting inserts, mounted on a beveling head, in rotational motion to bevel the workpiece. The motor and beveling head with cutter inserts all share the same axis. A gear reduction box, located between and operatively connected with the motor and beveling head, provides the low RPM and high torque needed to make practical use of carbide insert technolog y. In one embodiment, the motor is a hollow core air motor having vanes symmetrically arranged about the axis. |
