The basic idea is that for each depth you need to cut to, you switch depth keys to get the appropriate cut on your key blank.
It's cumbersome, but useful and keeps you from purchasing new, or upgrading your current equipment.
That said? 1 of 9 depth keys should be a bump key.
Also, I would not at all put it past a seller to advertise depth keys as bump keys.
They did in fact do just that at first, but I think ebay stopped the use of the term bump keys (could be wrong).
I bought a couple of depth key sets (cheap), and one set advertised as "bump keys", was actually the 99999 cut from a depth key set. The bump key set was 6 (99999) keys of different key ways.
If the price is really cheap I'd get the depth key sets! You get one key that is a 99999 and the others you can use to practice making bump keys. My first bump key was from a depth key set. I had to file a little off the tip and shoulder but worked out fine. It was a lot easier making them this way then from a spare key.
You can always take your 99999 cut keys to a cheap key cutter place (not a locksmith) and have more made. Don't tell them what your doing, just give them the keys and ask for copies. I took about 6 different such keys to a local store that also makes keys. They use a auto machine any any one in the store can do it. I handed the girl the six keys and said I wanted 5 copies each. All she said when she was finished was "those are funny looking keys". I smiled and thanked her while staring down her cleavage. Hey they were hard to ignor
