This router bit claims to be ideal for plastic cutting but when I tried this product for my industrial and scientific project, it failed to deliver .the bit broke after just a few uses and did not work as advertised, leaving me with a disappointing result. The only pro is that it was EASY to install, but unfortunately, that was outweighed by the cons - low quality and misleading claims. I would not recommend this product to anyone looking for a reliable plastic-cutting option..
