This application belongs to the field of milling cutter technology and discloses a wedge-locked three-sided milling cutter, including a disc body and multiple seats fixed on the disc body. A first cutter and a second cutter are respectively arranged on both sides of the seats. A connecting mechanism is provided on the disc body, including a moving component. The first cutter and the second cutter engage with the tooth grooves of the seats on their surfaces via surface teeth. Then, a locking component locks the first cutter and the second cutter.
