This shouldn't be too hard

I found this a few weeks ago. It's aluminum and opens up to reveal several different files. I was just wondering what is it used to file or ream? The back of it does have a chart but I couldn't get it to take a pic because it is inscribed into the case. It says-

Use For
No. Drill

a 1 75-74
t 2 73-71
p 3 70-68
e 4 67-65
n 5 64-62
d 6 61-60
i 7 59-58
n 8 57
g 9 56
m 10 55-54
a 11 53-52
d 12 51-50

I'm sure this has to do with the size of the file to be used. Their are only 7 files inside so I guess 5 are missing.

those are files for cleaning the tip from a oxy/acetaline type cutting or welding nozzle

I knew that would be easy. If I was a welder I would have known that! Now I wonder what it was doing at the beach under the sand.
