I was looking for something to mount the metal drills on our workshop wall. Nothing I found quite matched what I had in mind so I ended up making one myself.

The holes all have a 0.4mm tolerance (except for the 1m drill, that's at 0.6mm tolerance) and sink in 20mm deep. It's enough to hold the drills just fine while still leaving some space to mount it by just using the two screw holes in the lower half.

We used Spax 4x45 screws to do the job as the holder itself has a 35mm depth.

It will fit drills from 1 to 13 in 0.5 increments.
