This is one of the best bits I have ever used. Also cuts hard wood cleanly and quickly and prevents burn marks on the wood. Best of all it doesn't damage the edges of the router template like other bits I've used.
Pros
Perfect insertion loops with no nicks or dents on the bottom
After buying a new cutter, the very first cut, I hit the mark. I checked the carbide, there were no chips, so I kept using it. worked like a champion. very satisfied ! Most Chinese carbide shavings just get it wrong. I will buy more CMT bits in the future
Bought to replace the bit that came with the pan tool. This piece started burning with wood from the first cut. This bit cut wood like butter. I would buy this brand again if needed. Can't rate durability or durability yet but expect excellent performance.
