Review on Whiteside Router Bits 6400 Diameter by Jeff Hall

Reluctant to buy because I didn't know what I needed. I figured I could send it back if that was the wrong part. Very glad it fits perfectly in my Craftsman router. Used all day yesterday with no problems. Also, I went to my local "big hardware store" to look for this part before ordering online. They had nothing. The seller opened a new box and looked for this part. Apparently new routers don't come with this adapter? If I were to buy a new router, I would still need to order this part in order to use the router. what the hell.
