Make a 1/4 Inch Adaptor Necklace

Step 2 Drill

Drill a 4mm hole straight through the adaptor, going through the pilot dots.

Try to avoid the metal areas. This may take some trial and error.

I think I'll be the one to suggest putting it in a vise or something to avoid a horrible drill injury from holding something an inch or less from the bit while drilling.
