The CMT router bit is an Industrial and Scientific beauty. When I tried this product, the results were phenomenal. It made mortising a breeze, no matter the wood density. The downcut design allowed for clean cuts without any chipping, and it lasted quite a long time. However, the only downside is that it's a bit costly, but the quality is worth it. Overall, I am very satisfied with this router bit and would recommend it to anyone in the woodworking industry.
