Nice little router bit. It is a big thick bit that will take a strong router to pull. I am using a 2.25 HP router and even that can bog down if I do not go slow or take shallow passes. I Also find it works best in a router table at 13k rpms. It gave me clean cuts and no deflection using a chair template on some nominal 2x material (pressure treated southern yellow pine). I did use multiple passes never doing more than 3/8 of an inch on each pass. It may have been able to go deeper but I don't like stressing my tools and am not running a production shop, so slow and steady for max tool life.
The genius of these bit sis if you manage to dull a carbide insert you have 3 more sharp sides. Likewise if you are using reclaimed material and missed a nail then chip a tooth you get 3 more chances to mess up before needing just a new available carbide insert.
