These bits require adjustment (washers) to even come close to cutting the appropriate template. Even after that, some of the radius bits still don't match. There is no way to set this up. The beat used for the rails sounded like a jet engine getting ready to take off on my router table (completely unbalanced). And the plate cutter had a good sized chip in one of its 4 teeth. I returned these bits after a week and one use. I strongly recommend spending more money on better quality beats. This is not for those looking for a quality end product.
