Is there any noteworthy difference between drills and pickaxes? Or is it just the power for drills is varied depending on if it is vertical and horizontal and picks have just a single power stat that effects both the same?
Iron and titanium drills and pickaxes are essentially the same aside from the drills having split vertical/horizontal power instead of a single flat value. There are a few different pickaxes and a special drill with different special effects in addition to their power differences. Drills generally have slightly higher durability as well.
