Abstract
The invention provides a cutting tool for incising a helical cut around the internal surface of a hollow member comprising a tool carrier adapted for insertion into the hollow member adjacent the internal surface thereof to be cut; a cutting block carried by the tool carrier and adapted so as to be located, in use, within the hollow member, the block being freely pivotally mounted on the carrier about an axis normal to the axis of relative rotation, in use, of the carrier and the hollow member, and a cutting member secured to the cutting block and extending from the block generally parallel to the axis of pivot thereof upon the carrier, and being arranged such that, in use, as the tool moves (relative to the hollow member) in a helical path around the internal surface, the cutting edge of the cutting member moves (relative to the hollow member) in a direction generally towards the axis of the pivot of the cutting block on the shaft.
