I don't know why they got such good reviews. 2 of these dies are larger than the plywood sold in American stores and lumber mills, as listed on the label, and they are all larger than the label at the factory. Get a 1/2 inch nozzle. For a good fit, it should be 15/32 inches. (0.469 inches). The label on the box says 31/64" (0.484"), which is already 1/64 oversize. This is unacceptable even if the bit size matches the label. Investigate this beforehand, even if the product is not suitable forโฆ
