Bound Pickaxe and Beast Mode. Not exactly a surgical dig, but it'll get the job done fast.
GraviSuites upgrades for the IC2 Diamond drill, the "Advanced Diamond Drill" is hard to beat. If enchanted with efficiency 5 it mines all common stuff instantly. It mines both rocks and dirt/sand/gravel etc. It has several modes including a precision mode for when you are breaking machines in your base and don't want to take down the wall too, it got a 3x3 mining mode to make it function like a TiCo hammer/excavator.
The drill is accompanied by the a chainsaw for instant wood type breaking. Also doubles as a silktouch(mode that can be toggled on/off) shear for shearing vines, grass etc. Also allows shearing of sheep by rightclick. Deals a decent amount of damage if used as weapon, but not enchantable as one.
The there is ofc the Vajra that instant breaks everything at the cost of heavy power consumption. Rather good for mining lots of obsidian and similar hard blocks, but probably too powerhungry to be used on normal blocks(there would be no need to as the drill will instant break those at a fraction of the energy cost).
All tools are powered by any of the GraviSuite chest armours which can be in turn powered by different tiers of battery packs kept in your inventory, greatly extending your working range.
For weapons I cant seem to get around the heavily enchanted Sword of the Zephyr from TC due to its AoE ability. Then I don't mind having to hit a single mod once more tbh, when I can hear that WHOOOSH and see an entire pack of mobs go down.
