so if i were buying a drill bit for standard bolts (countersunk ones for moon holds), what size hex bit would it need? think those bolts are m10 but what size does that make the hex part?? cheers.

Don't know about moon, but an m10 bolt would normally use a 17mm socket

From memory I think it's a sawn-off 6mm allen key you need.
