An upcut bit is best used when you want to efficiently remove chips and debris from the cut, such as when cutting grooves or slots in wood or plastic. It also helps achieve a clean cut on the bottom surface of the material, though it may cause some tear-out on the top surface. I will generally use a Downcut bit on the first few passes , then switch to an Upcut for the rest of the cuts.
