Drills

Drills are tools used in the Mining skill to obtain ore and stone, similar to Pickaxes. They can use the same Enchantments and Reforges as pickaxes do. They also have a Breaking Power just like pickaxes.

Drill Parts are additional upgrades for drills. There are currently three available categories of Drill Parts, being Fuel Tanks, Drill Engines, and Upgrade Modules.

Fuel Tanks are used to increase the amount of fuel a drill can store.

Drill Engines increase the additional Mining Speed bonus of the drill.

Upgrade Modules (of which there is currently only one) provide miscellaneous buffs to a drill.

Upgrading
On upgrading a Drill to a higher tier, such as forging a Mithril Drill SX-R226 into a Mithril Drill SX-R326, it will keep all its Drill Parts and extra stats, including Enchantments, Reforges, applied Hot Potato Books and used Recombobulators.

Drill Parts
Drill Parts can be added to a Drill by combining them in a Drill Anvil.
