The InfiMiner is a tool only available with creative mode or NEI/TMI. It looks like a Hammer with Ardite plates, a Cobalt head, and a Slime handle. It does the same amount of damage as the Bane of Pigs, has the same Durability and has a Mining Speed of 71588.11, so when holding left-click it will mine at a speed compared to mining in creative mode, but with drops.
