The Diamond Drill is an upgrade of the Mining Drill. It is similar to having a Diamond Pickaxe and Diamond Shovel all in one tool. However, it is a bit faster, has infinite durability, and it requires electricity to be used. The Diamond Drill can mine Obsidian about twice as fast as a Diamond Pickaxe. If used in combat, it deals 2 damage (1 full heart) every hit.

Recharging and EU UsageEdit

It uses around 50-80 EU per block mined. The Diamond Drill can be charged in a Generator, BatBox, MFE, MFSU and a Charging Bench MK1, 2 and 3. However, without a BatPack or LapPack, the drill will last for an extremely short time, since it can only hold 10,000 EU. It is highly recommended to bring one of the above (or a few RE Batteries) along in order to recharge your drill.
