The number of teeth on a biscuit joiner blade affects the smoothness and speed of the cut. Blades with fewer teeth (like 6-tooth designs) remove material quickly and are less prone to clogging, making them ideal for efficient slotting in hardwoods and softwoods. All the listed blades—such as the 4" Carbide Tipped Blade for Makita, 4" Replacement Joiner Blade Porter Cable 5558, and Amana Tool LAM400T6—feature 6 teeth, balancing fast cutting with durability. If you need a faster, rougher cut, lower tooth counts are best, while higher tooth counts (not shown here) could provide a finer finish. You can choose the tooth count that best matches your working style and material.
