The flute type influences chip removal, cut finish, and workpiece integrity. Up-cut flutes (like the Solid Carbide CNC Foam Up-Cut Cutting Square End Spiral) efficiently remove chips upward, ideal for deep cuts in foam or soft material. Down-cut flutes (such as in the 1/2" Spiral Flute Solid Carbide Plunge Bit Downcut) push chips down, leaving cleaner top surfaces—great for laminates. Compression bits combine both, producing clean edges on both surfaces, perfect for plywood and laminates (e.g., CNC Solid Carbide Mortise Compression Spiral). With all these types available, you can choose the ideal flute style for your application.
