An "up-cut end mill" removes the chips in an upward direction, which creates clean pockets at the cost of a slightly rougher top surface, like tearing out some of the plywood veneer on the top surface, but leaving a clean bottom surface as it mills through it. If a smooth bottom to a pocket is the goal, up-cut is generally the ideal choice.
