This kit is just average. Although all the inserts fit well, they are low grade metal, and without a centering locator which should always be supplied with one of these kits, the inserts are difficult if not impossible to center, resulting in worn out bushings. Rockler has a much higher quality kit, made out of brass, and includes two centering pins, 1/4 inch and 1/2 inch shafts to properly align the templates. And the pricing is very similar.
