Doesn't look like much, but lemme tell you an 1/8" drill bit spinning inside your knuckle at ~1,400 rpm is a weird and painful feeling to say the least. Finger swelled up a bit and is a bit tender, but luckily it seems I missed anything important like major blood vessels, nerves, or tendons.
Surprisingly (or maybe not), this isn't the first time I've drilled into my hand, but it was by far the deepest I've done it. Brought the part back to the shop to finish the job on a proper drill press.
Lesson learned, use the right tool for the job (ok, knew that already, and will probably still improvise in the field)
