When you're shopping for individual router bits or router bit sets you'll mainly see two different types: carbide-tipped bits and hardened steel (HSS) bits. Solid carbide tipped router bits and tungsten bits may also be available.
How do I choose the right bit for my router?
Woodworking router bits come in a variety of sizes. To ensure safety and the best possible results from your routing, you must adjust the speed of the router to suit the diameter of the router bit. The general rule is the larger the bit, the slower the maximum allowable router speed.May 30, 2019
