This cutter actually cuts relatively smoothly but generates quite a bit of vibration compared to other flush cutters. If you look at other reviews of this company's other router bits, this is a common complaint. If they could control the quality together, that would be nice. This drill is massive and seems almost made for a shaper. I wanted this piece to work, but it just gave me a lot of vibration. ************************ ОБНОВЛЕНИЕ: на следующий день после того, как я оставил свой отзыв, компания связалась со мной и немедленно прислала мне замену, которая работала much better. As a small business owner, I understand that things happen, but how a business handles it is important. I appreciate that this company reached out to me to fix things. They gave me suggestions and troubleshooting steps and when that didn't work they sent another router bit. Email communication was quick and they were very responsive.
