bits that I have radius 1/8", 3/16", 1/4" and 5/16" instead of radius 1/8", 1/4", 3/8", 1/2". as stated in the description. and product photos. The overall outside diameter of the largest bit is only about 1-1/8" instead of the 1-1/2" as stated in the product description and photos. If you are using 3/8" cutters " and 1/2" radius, you will be disappointed with this set.
