Review on Whiteside Router Bits 1412 Diameter by Daniel Russell

I bought this round bit for a specific project. Finishing touches on a BBQ plate I made for my brother-in-law's birthday present. I used it to break up the Ajus shards around the perimeter. As expected, he did a great job. I bought a set of three sizes not knowing which size I need. The measurements marked differed from the cuts made. That's probably my misunderstanding.
