Combination up and down-cut spirals are excellent for getting an optimum finish on both sides of solid wood, veneered boards or laminates that are faced on both sides. This is when the combination spiral router cutter comes into its own. If the router is grooving or trimming veneer edgings, the finish is guaranteed to have clean edges on both faces. In operation, the upper down-cut part of the spiral severs the grain on the top surface of the board and the lower up-cut severs the grain on the underside with both faces being sheer cut.
