Flute type (up-cut, down-cut, compression, ball nose, etc.) determines chip evacuation and the quality of the cut edges. Down-cut flutes push chips down for clean top surfaces, up-cut flutes evacuate chips upward and are excellent for mortising, and a compression bit combines both for clean edges on both surfaces—ideal for double-sided laminates. Ball nose flutes are perfect for 3D contouring. For example, the Amana Tool 46170-K is a compression spiral bit, great for flawless edges, while the Amana Tool 46415-K is a down-cut bit for crisp surface finishes. With many flute types available, you can select the ideal bit for your specific material and finish requirements.
