The number of flutes on a straight mortising bit affects the finish quality, chip removal, and feed rate. Most commonly, 2-flute bits are preferred as they provide an excellent balance between smooth finish and efficient chip ejection. Two flutes also help maintain stability and reduce vibration. All the products listed, such as the Freud 12-128, Amana Tool 45414, and Freud 04-102, feature 2 flutes, ensuring users get a smooth cut and efficient operation. While more flutes can offer even finer finishes, the 2-flute design is the optimal choice for most woodworking applications, and is well represented in the available product range.
