The Arcane Bore is a magical mining tool. It allows one to mine vast quantities of material in a relatively short time, though it is a bit expensive to operate.
The Arcane Bore needs a Redstone signal to activate. Any items mined is drawn towards the front of the bore and then ejected out its back. You can alter the facing of the bore by using Arcane Tinkering Tools.
Placing a chest at the exit side of the bore will cause the ejected items to enter the chest instead.
