Was a little confused by the individual size markings; The 6 boxes were labeled 1/2 x 19.05, 22.2, 25.4, 28.54, 31.74, and 34.9, respectively. By converting these metric values to inches, I actually got 1/8th, 3/16th, 1/4th, 5/16th, 3/8th, and 7/16th bit radius. It differs a little from the lettering, but overall the quality seems excellent. Yes I would buy them again because they are a steal for the price.
