What can you say about router bits? Well you can readily find out the quality of the carbide cutters which in this case is excellent. The sharpness was evident when cutting a bead through hundreds of lineal feet of boards without any chatter or vibration. When the job was finished, the bit was as if brand new. I have had problems with previous Chinese bits whereby I had to get one in a hurry at a local big box store and was sorry because of the result with cutting etc. These Freud bits (And I have many now) are in my humble opinion, the best available and in the long run, will save you money and give you the best result in satisfaction.
