The first thing that impresses you about this bit, is the size. It is really large. The cutters are huge and as such, require more care than usual, especially if you are using it in a hand held router. I've been using the bit in a 2 1/4 HP router, with a D handle installed. I jointed and squared 2 large boards 8ft x 12" x 3", hand held. I butted the router base against long straight edges and took cuts of about 1/16" to 1/8". The bit performed flawlessly, giving me very smooth edges on the boards, which were laminated 3/4" cabinet grade plywood (3) with a 3/4" layer of solid red oak. Of course, the 2 1/2" cutting length wasn't long enough to do the whole board. After making about a 2 1/4" cut with this bit, I turned the boards over and used a 1/2" trim bit, bearing on the bottom, to finish off the cuts. The job turned out great, only requiring light passes with a smoothing plane to finish off the job. I'm very pleased with the speed and ease that this bit jointed and squared these large pieces. Nothing else in my shop worked as well or as quickly. Now to the bad part. I got a little careless on the second board, while cutting one of the 8ft sides. I didn't keep the router dead flat on the surface and dipped into the cut. In a split second, that long cutter took a big bite out of the side and then climbed up and out of the cut, twisting me to the left. Fortunately, the D handle base is a very secure base, that allows you to have a very good hold on the router, so nothing happened other than scaring me half to death. But, if someone had been standing close to me on the left, the router would have been in their face in an instant. I've been using routers for over 30 years and never had a router do that to me before. Of course, I usually use a router table when possible, which is the sensible thing to do with such large bits. I've got other projects planned, where I'll be using this bit and router configuration again as a hand held jointer. But, the next time, I'll make and install a much larger router base plate that will keep the router flat on the work surface. That should make things idiot proof....
