trying out this drill, I like the balance so far, mining speed and pollution are more or less same as I would expect from a mk2 vanilla and I very much like the design and the realist of this drill, but the mining radius is too much, this allow "cheat" a bit too much, specially with infinite resource (not important).

My point is that the extra one radius for vanilla is here for convenience, it's a middle ground between realist and convenience. Omega drill have 5 extra case to mine compare to its physical body. I suggest at least to reduce it to one to balance thing a bit.

On extreme opinion since omega drill are so big I don't think they even need the extra one mining range.
