ABSTRACT:
A tool head assembly for use in preparing a tube for welding including a center pilot which is rotatable. The center pilot is adapted to enter a bore of a tube to center the tool head assembly by being provided with ball bearings which rotate around the internal surface of the bore of the tube. In addition, the ball bearings are moveable thereby enabling a required operative diameter to be selected which enables the center pilot to enter the bores of a batch of tubes having a range of internal bores. The center pilot is engageable with a tool holder which is connectable to a machine tool. The tool holder also supports a pair of bevelling tools and a facing tool. In use the center pilot is adjusted to the required operative diameter and the rotating center pilot entered into the bore of the tube, which is clamped externally, to facilitate rotation of the ball bearings around the bore of the tube to center the tool head assembly thereby enabling cutting of the surface of the tube into a predetermined shape to be effected, by the bevelling tools and the facing tool, to prepare the tube for welding.
