An expandable tool includes a cutting block set. The cutting block set includes an upper cutting block and a lower cutting block, arranged longitudinally. The upper cutting block includes upper block splines having an upper block angle. The lower cutting block includes lower block splines having a lower block angle. The upper block angle is greater than the lower block angle, which directs the upper cutting block to extend radially further outward than the lower cutting block.
