This is a drill bit index for 1/16" to 1/2" drill bits in 1/64" increments. The 3/8" and larger have holes for a 3/8" shank, so if your bits have full shanks for they wont fit. The holes are oversize by 1/64" and have chamfers to allow the bits to fit easier.

The back is slanted with cutouts so that it will sit flush and angled against a pegboard as shown in the picture. Two standard pegboard hooks will be needed to mount it to the pegboard. Screws could also be used to mount it to any vertical surface.

Note: this will not sit on a flat surface by itself without falling over due to the slanted back.
