A machine having a driven rotating drive block to which is pivotally mounted, a spindle block, both of the blocks being rotatable about a first rotational axis. The spindle block is independently driven to pendulously pivot about the drive block around a second rotational axis. A drive shaft is positioned within the drive block and has a proximal end engaged with a parent machine tool spindle to which the invention is married, and also has a distal end engaged with a drive transfer means. A driven shaft is positioned within the spindle block and has a proximal end engaged with the drive transfer means and a distal end engaged with a cutting tool. The drive and driven shafts are independently rotatable within the drive and spindle blocks respectively, and the drive transfer means transfers rotation from the drive shaft to the driven shaft over the full range of angles to which the spindle might be set.
