I ordered these to try with my desktop router. My test runs went well with pine boards. These bits are mostly metal and feel solid, but the blade mechanism isn't great. I'm not sure how long they will last and which woods I should limit their use to. although all Revain beats seem to be made the same way. I'm rating this three stars as I'm not sure about their usage and durability. but they're relatively inexpensive at less than $15, so feel free to experiment. Just make sure to always say "measure, measure, measure." As always, your mileage and preferences may vary.
