Flute type determines chip evacuation and the quality of the cut. Up-cut flutes excel at pulling chips out of deep cuts and are ideal for foam, as in the Amana Tool 46272-K and Amana Tool 46294. Down-cut flutes minimize surface tear-out but are less common for foam. Straight and spiral flutes are used for general-purpose cutting, while V flutes and specialized geometries allow for unique carving effects. The range in this category covers up-cut, spiral, and ball nose designs, so you can choose the optimal flute style for your foam cutting router bits to achieve your desired finish and chip control.
