I have just completed a fairly complex woodworking project. I had to cut 48 slots 1 1/2" long and 7" long in 3/4" thick plywood. I used this bit in my Milwaukee plunge router to get the job done. In fact, it took longer to install and mark than cutting. This beat worked like a champ. Cuts very quickly and cleanly. The carbide tips held up well. This thing cuts in slot #48 just as well as slot #1.
