There are several benefits of using router bits. One is that they can produce very clean and precise cuts. This is because the cutting edge on router bits is much smaller than on saw blades, so there is less chance for the material to be "torn" rather than cut. Router bits also tend to have a longer lifespan than saw blades since they are not as likely to get dull as quickly. Additionally, router bits come in a wide variety of sizes and shapes, so you can find one that is specifically designed for the job you need it to do.
