Based on my observations these router bits from this brand are not worth the investment in the industrial and scientific world of cutting tools .While they do offer sharpness and precision, they still have a tendency to burn out quickly and produce a lot of debris while in use. The one pro is that they do provide a clean cut initially, but the frequent need for replacement outweighs this benefit..
Pros
Long-lasting durability due to carbide material and Spektra coating
Cons
Requires proper storage and handling to prevent damage to delicate cutting edges
The bit broke after many hours of use. All my own fault for the breakdown. Bought from another manufacturer and completely dissatisfied. Now I'm staying with Amana.
