Abstract
A boring tool is provided with rotary cutting inserts which rotate as a result of the forces which act on the inserts as the tool bores a workpiece. The inserts are positioned on the tool so that the cutting point of each insert is located in a different radial plane along the axis of the tool. The inserts are also positioned on the tool so that the radial distance of the cutting point of each insert from the axis of the tool is different. The non-symmetrical positioning of the inserts on the boring tool provides improved performance of the tool over a tool in which the inserts are symmetrically positioned.
