Alright, I have looked around extensively for this and couldn't find anything, so here I go.
By combining a regular Drill with 3 Iridium Plates, on top of an advanced circuit, you obtain a drill with 2x EU capacity (requires 20 SU-Batteries to recharge) and a special ability.

(Don't mind the Rubber, used it as a placeholder.)
But what's this special ability that I was talking about? Well, due to the properties of Iridium and the Adv. Circuit, the Drill has the ability to enter "Overdrive Mode," similar in execution to EqEx's tools (f.e Destruction Catalyst), by clicking this key [configurable] the Drill will begin to charge it's internal capacitors with EU that it will take from the Drill's rechargeable storage to the point of about 90 EU. As well, this internal storage can be transferred back to the regular storage by the same key, but with the loss of 1 EU per 10 EU transferred back.
This "Overdrive Mode" entails the ability to drill a 3x3 area in one go for 9 EU stored away in it's internal "battery" (time vs. convenience). So in this way, you can drill 10 3x3 squares before the capacitors run dry again and need to be recharged.
Opinions/critiques are welcome.
(P.S If I had the time to, I would turn this into an addon myself, but I figured I might as well leave this here for a more experienced modder.)
