Does a 2" (5 cm) cutting depth 1/16" (1.6 mm) drill bit even exist? If not, is there any way for me to make this hole? I'm drilling a fiberglass/foam sandwich if it matters, and I want to make a hundred holes. My cheap standard drill bits cut the fiberglass just fine, but are half the length I need. And yes, I'm aware that the reason they're kept short is so they don't break all the time.
This probably sounds weird – it's for installing a starlight ceiling effect in a fiberglass float tank.
