Multi-Drills are effective on anything a pickaxe or shovel would be able to mine. With an upgrade, they can also work on wooden materials! They also make a good melee weapon. All customization is done with ordinary crafting.
Note that this information assumes you are playing the latest version. Ancient versions are very different.

Note on energy: This mod has no built-in way to generate, store, or charge items with FE. Try something like Powah or Silent's Mechanisms.
By default, the energy consumption when mining a block depends on the hardness of the block, the drill head, and the level of the Efficiency enchantment on the drill. The formula can be changed in the config file (currently not working). There are also some unused variables, such as the level of Silk Touch and Fortune. The config file contains a full list of variables you can use.
Drills are now Silent Gear tools. The following parts are required. Note that the head is a compound part which can be crafted from different materials. The rest are simple parts. Motors and batteries have a few variants, but cannot be customized beyond that.
Drills support some Silent Gear upgrades (tips, coatings), but not bindings or grips.
