Industrial and Scientific customers will be thrilled with this cutting TOOL. My analysis of this product showed that it is durable and precise making it perfect for intricate cuts. The carbide tipped edges stayed sharp through frequent use and the comfortable grip made for easy handling .The only downside is that they are a bit pricier than some other options on the market. Overall, Amana's Corner Router Cutting Tools are a great investment for anyone in need of high-quality router bits..
