The number of flutes in a plunge router bit influences chip removal, surface finish, and cutting speed. Fewer flutes (like 2-flute bits) excel at clearing chips and are ideal for softer materials or roughing, while more flutes (3 or 4) deliver a smoother finish and can handle harder or more abrasive materials. For example, the Amana Tool 46577-K features 2 flutes for efficient chip evacuation, while the Amana Tool 46473 with 3 flutes balances finish quality and speed. Since products are available with 2, 3, or even 4 flutes, you can choose based on the material and finish you desire.
