The arbor or bore size must match your biscuit joiner's spindle for safe and accurate operation. The most common bore sizes are 22 mm and 7/8", depending on the joiner’s make and model. The Makita A-95118 and Porter Cable 5558 each specify bore sizes (Makita uses 22 mm, Porter Cable uses 7/8"), while the Amana Tool LAM400T6 features a 22 mm bore for compatibility with various brands. With several bore sizes available, you can find blades that fit your joiner precisely, ensuring safety and performance.
