Get your jobs done faster with Power Tools. Two different drills let you carve holes into the terrain quickly and easily to speed up mining for ores or just general building. The Jackhammer excels at breaking hard blocks quickly. The harder the block, the quicker it breaks! Watching trees fall with the Chainsaw is a satisfying way to gather wood quickly.
A single chop from the Chainsaw brings an entire tree crashing down. The Chainsaw is also pretty quick at trimming leaves. Just don't try to use it on anything else. It might break.
The Jackhammer makes mining those heavy blocks (like ores and obsidian) much easier. The harder the block, the faster it breaks! Don't try to use the Jackhammer on soft squishy things though. That won't work so well.
