These Industrial and Scientific router bits are simply overpriced. While they do provide a decent cut, they seem to wear down much quicker than other router bits in the same price range .The lack of durability is a major issue especially for those using these bits in a professional setting. The only pro is the initial quality cut, but it quickly deteriorates..
Pros
High-quality and durable, made with carbide material
Cons
Slightly more expensive compared to other router bits in the market
