Drill bits cylindrical case

Cylindrical case for carrying 19 drill bits from 1 to 10 mm diameter in 0.5 mm increments.

In the center has a hole to put other bits or tools. I made an adapter cylinder for 5 concrete drill bits, from 5 to 10 mm.

There are two models of lid, one with eyebolt for a carabiner and the other without.

Although it is made for metric system drills, I think it can be used for drills of equivalent sizes in gauge (I haven't tested it). This is the table of approximate equivalences, taken from Wikipedia:

mm-gauge-Inchs
1-61-1/32
1,5-53-1/16
2-47
2,5-40-3/32
3-31-1/8
3,5-29
4 22-5/32
4,5-16
5-9-3/16
5,5-3-7/32
6-A
6,5-F-1/4
7-J-9/32
7,5-M
8-O-5/16
8,5-Q
9-T
9,5-V-3/8
10-X

In any case, the design can be modified for inch drills.
