As an industrial and scientific user, I have extensive experience when it comes to router bits. According to my experience, the Steel Dragon Tools Tungsten Carbide is one of the best in the market. The great thing about these bits is that they make cutting a breeze while also producing precise edges. They are durable and can withstand heavy usage, making them perfect for frequent use. However, the downside is that these bits can leave a rough finish on softer materials. Overall, I highly recommend these router bits for any industrial or scientific cutting needs.
