there are 4 widths offered. pick the one that you want to work with...I purchased the 3/8" version

Is there an indication of which bit is which in this set ...for a newbie?

There is a chart in "show more" about the purchase https://www.amazon.com/gp/product/B0779GS6XG/ref=ask_ql_qh_dp_hza

Why is there a fifty percent markup between the 1/4" set and the 3/8"? It just cost you a sale.

More steel and machine setup takes time. Thickness determines hardening time spent. Machining time is way more in setup than it is doing the job. Has to be right the first time. Maybe one is more popular than the other. Maybe they have to shut down a line to make one or the other. Maybe, Maybe, Maybe
