Accusize Industrial Tools No 10-10A Conbination H.S.S. Keyway Broach Sets in Fitted Box, 5100-0012

So the broaches are 1/8, 3/16, 1/4 and 3/8, right? What length is the longest broach? I want to make sure I have enough travel in my press

What sizes are in the box?

What is the maximum thickness object that this can be used on?

Is there a 5/8" shaft in the set?
