This mod adds 3 new tiers of drills (new artstyle), each requiring 2 of the previous tier.
Advanced Drill (Tier 2 Electric Mining Drill): double the output of the standard drill. Requires steel
Elite Drill (Tier 3 Electric Mining Drill): double the output of the Advanced Drill, plus some. Requires batteries and advanced circuits
Ultimate Drill (Tier 4 Electric Mining Drill): double the output of the Elite Drill, plus some. Requires speed modules and processing units

Mod is mostly intended for those who want more output without creating huge farms of mining drills. Pollution is slightly reduced for each tier of drill, down to half by the Ultimate Drill.
