The thing is, in the vacuum conditions conventional drilling doesn't work. You can't use lubricants because it is a near vacuum (and anyway you'd have all the weight of lubricants to source somehow). Meanwhile the regolith is quite soft. And you want to carry as little mass with you as possible, don't want long continuous drililng shafts. Moles seem to be the best way to drill there.
