We recently purchased a set of router bits for our woodworking business and found that these bits were top notch. Based on our own experience, the Amana Tool AMS 136 Carving Collection provides great precision and sharpness .The variety of shapes and sizes in this set allows us to be creative and produce unique and intricate designs. The only downside is that they may come with a higher price tag than some other options in the market. However, the quality and durability make it worth the investment. Overall highly recommended for anyone in need of high-quality industrial and scientific cutting tools..
