Review on Woodworking Milling Cutter Bearing Trimming by Joe Jordan

milling cutter arrived and I installed it in my Ryobi hand router. When turned on, the chisel became so loose or off balance that it caused severe vibration and a loud howl. Tried a small cut and it was so bad the bearings bounced off the job. The item has returned. To be fair, the exchange time was very quick. Got a replacement today. Thrown out and exactly the same problem. vibration and howling. I've tried all my other bits (about 8) and NONE of them work like this. Garbage. Don't waste your time or money.
