Based on my observations the industrial and scientific world needs a reliable cutting tool .And the Amana carbide straight plunge production cutting tools deliver just that. These router bits are phenomenal in their cutting performance, speed, and efficiency. Their razor-sharp edges are able to slice through any material without leaving any burn marks. They MAKE cutting wood, metal, or plastic a breeze. Their only con is that they`re slightly pricier than some other router bits on the market. However, if you're looking for a high-quality tool that will last long, it's worth it..
