The CMT 4-inch downcut router bit is a game-changer for woodworking. As my tests showed, it delivers a smooth and accurate cut, leaving no tear-out along the cut or on the surface of the material. The carbide cutting edges stay sharp for a long time, making it an excellent investment for those who demand high-quality cuts frequently. However, the price is slightly higher than some of its competitors, which could be a con for some customers. Overall, I highly recommend this router bit for professionals and DIYers alike.
