The best drill for Earth in Mine a Planet depends on whether you are a brand-new player still on the Wooden Pickaxe or an end-game player rotating back to Earth for fast Drill Piece bursts. For new players, the optimal progression is Wooden Pickaxe → Copper Drill → Stone Breaker → Iron Hammer. For end-game players rotating back, the optimal drill is the highest-tier drill available — typically the Astral Annihilator — because its massive ore multiplier compounds Earth-tier Drill Piece income significantly. This guide covers both use cases and the recommended drill choice at each Earth progression milestone.
For the complete drill tier list including S, A, B, and C tiers, see our Mine a Planet S-tier drill list. For Earth farming routes, see our Mine a Planet fast Drill Piece farming guide. This principle applies broadly across all progression stages and is one of the most reliable optimization levers in the game.
Earth Drill Progression for New Players
The Earth drill progression for new players is straightforward — craft the next drill as soon as you have the materials, and replace the current drill immediately. The progression is Wooden Pickaxe (starter) → Copper Drill (10 Common Ingots) → Stone Breaker (15 Common Ingots) → Iron Hammer (5 Iron Alloys).
The damage progression on Earth is roughly 30 → 60 → 90 → 280, which means each upgrade makes Earth farming meaningfully faster. The ore multiplier progression is 1x → 1.5x → 1.75x → 2.5x, which compounds into significant Drill Piece income gains.
| Drill | Damage | Ore Multiplier | Replace When |
|---|---|---|---|
| Wooden Pickaxe | 30 | 1x | After crafting Copper Drill |
| Copper Drill | 60 | 1.5x | After crafting Stone Breaker |
| Stone Breaker | 90 | 1.75x | After crafting Iron Hammer |
| Iron Hammer | 280 | 2.5x | After unlocking Mars |
Why End-Game Players Rotate Back to Earth
Many end-game players rotate back to Earth for short Drill Piece bursts, even after they have unlocked all the late-game planets. The reason is that Earth has the shortest ore respawn timer in the game, which makes it the most efficient Drill Piece source per hour of grinding time. End-game players with high ore multipliers can earn 100,000+ Drill Pieces per hour on Earth, which compares favorably to late-game planets despite the lower per-node reward.
For an end-game player on Earth, the optimal drill is the highest-tier drill available. The Astral Annihilator's 32x ore multiplier turns every Earth swing into a massive Drill Piece income boost, which is why end-game players who own an Astral Annihilator prefer Earth for fast Drill Piece bursts.
| Player Tier | Best Earth Drill | Reason |
|---|---|---|
| New player | Copper Drill, Stone Breaker | Mandatory progression |
| Mid-game | Iron Hammer | Mandatory progression |
| Late-game | Mythril Destroyer or higher | Faster farming |
| End-game | Astral Annihilator | Maximum ore multiplier |
Common Earth Drill Mistakes
The most common Earth drill mistake is to hold on to the Wooden Pickaxe for too long after crafting the Copper Drill. The damage gap between the two drills is 2x, which means Earth farming with a Wooden Pickaxe after crafting the Copper Drill is wasting time on every swing. Replace the Wooden Pickaxe immediately after crafting the Copper Drill.
The second mistake is to skip the Stone Breaker and go straight to the Iron Hammer. While skipping is technically possible, it leaves Common Ingots on the table and wastes the opportunity to experience the full C-tier progression. Most players should craft the Stone Breaker before moving to the Iron Hammer.
The third mistake is to overfarm Earth after unlocking Mars. Players who linger on Earth for additional Drill Pieces after Mars unlocks waste hours of grinding time on a planet they have already out-scaled. Move to Mars as soon as you have crafted the Iron Hammer.
Reforge Strategy for Earth Drills
The reforge strategy for Earth drills depends on your progression stage. For new players, reforge the Wooden Pickaxe for practice but do not invest serious Drill Pieces. For mid-game players rotating back to Earth, reforge the Iron Hammer for high Ore Multiplier before each Earth burst session. For end-game players, the bound Astral Annihilator with a high Ore Multiplier roll is the optimal Earth drill — no reforge strategy is needed because the bound drill persists across rebirths.
For a complete walkthrough of the reforge priority and the optimal stat rolls, see our Mine a Planet reforge strategy guide. The exact mechanics vary slightly by patch, but the underlying principle remains consistent across all player playstyles.
Drill Switching Cadence on Earth
Earth is the planet where drill switching matters most, because the early-game progression depends on quickly moving through Stone, Copper, and Iron-tier nodes that each favor different drill stats. The optimal cadence is to keep three drills equipped in your active slots: a Wooden Pickaxe for Stone, a Copper Drill for Copper nodes, and an Iron Hammer for Iron nodes. Switch drills whenever you enter a new biome, and always prioritize the drill with the highest Ore Multiplier for the current biome.
Players who stick with a single drill throughout Earth typically lose 20-30% of their potential ore yield, because the Ore Multiplier rolls on a single drill are tier-specific. By maintaining three specialized drills, you always have the right tool for the biome you are in.
When to Move Off Earth
The transition off Earth should happen as soon as you have two full batches of Iron Alloy and one full batch of Titanium Plate stockpiled in your inventory. Hitting this material threshold means you have enough to craft the next-tier drill and feed it with ingots for the first hour, which removes the early-game starvation risk that plagues players who move to Mars too early. If you do not have these materials stockpiled, stay on Earth and keep farming until you do — the extra few hours on Earth will save you many more hours of stranded-inventory frustration on Mars.

Frequently Asked Questions
What is the best drill for a brand-new player on Earth?
The Copper Drill is the best starter craftable drill for new players. It doubles the damage of the Wooden Pickaxe and adds a 1.5x ore multiplier, which makes Earth farming meaningfully faster. Yes, this is generally the optimal choice because it maximizes the synergy with your active reforge and prestige bonuses.
Should I craft the Stone Breaker or skip it?
Most players should craft the Stone Breaker before moving to the Iron Hammer. The Stone Breaker adds meaningful damage and ore multiplier, and the crafting time is short. Generally yes, but the optimal timing depends on your current resource reserves and your active biome's node HP profile.
Can I use a Mythril Destroyer on Earth?
Yes, but it is overkill. The Mythril Destroyer breaks Earth nodes in 1-2 hits, which is wasteful given Earth's low node HP. A Common or Rare drill is usually more efficient on Earth. Yes, but the optimal approach depends on your current progression stage and your stockpile of supporting materials.
Why do end-game players rotate back to Earth?
Because Earth has the shortest ore respawn timer in the game, it is the fastest Drill Piece source per hour for players who own high ore multiplier drills. Even with lower per-node rewards, the faster respawn timer yields more Drill Pieces per hour.
Should I reforge a Common drill for Earth farming?
No, the reforge cost on Common drills is low but the stat ceiling is also low. Save your reforge budget for Rare or Legendary drills, which provide much larger reforge returns. Generally yes, but the optimal timing depends on your current resource reserves and your active biome's node HP profile.
Earth Biome Variants and Drill Choice
Earth has three biome variants — the surface, the forest, and the underground cave. Each biome has slightly different node HP and respawn timers, but the drill recommendations are essentially the same across all three. The surface biome is the easiest with the lowest node HP, the forest biome has medium HP with denser node clusters, and the underground cave has the highest HP but the richest ore drops.
For a brand-new player, the optimal drill progression across all Earth biomes is the same C-tier sequence (Wooden Pickaxe → Copper Drill → Stone Breaker). For an end-game player rotating back to Earth, the optimal drill is the Astral Annihilator regardless of biome because its 32x ore multiplier covers the node HP gap instantly.
How Earth Drills Compare to Late-Game Drills
The damage gap between an Earth drill like the Copper Drill (60 damage) and an end-game drill like the Astral Annihilator (4,800 damage) is 80x. This is the largest single stat gap in the entire game and explains why the game feels so different at end-game compared to early-game.
The ore multiplier gap is similarly large — the Copper Drill has a 1.5x multiplier, while the Astral Annihilator has a 32x multiplier, a 21x gap. Combined with the damage gap, the Astral Annihilator is roughly 1,700x more efficient per swing than the Copper Drill on the same planet.
Chest Farming With Drills on Earth
Earth has a small number of hidden chests that grant bonus Drill Pieces when opened. The optimal drill for chest farming is whichever drill gives you the fastest movement speed, not necessarily the highest damage. Most drills have the same movement speed, but some Epic and Legendary drills grant a small movement speed bonus through their reforge stats.
A drill with a high Movement Speed reforge lets you traverse the Earth surface faster to reach chests, which is meaningful if you are chasing every chest spawn. For most players, however, the drill you have equipped is fine for chest farming.
Why Earth Remains the Best Drill Piece Burst Location
Even at end-game, Earth is the fastest Drill Piece source per hour for players with high ore multipliers. The reason is that the respawn timer is the shortest in the game, which lets you swing faster than on any other planet. With an Astral Annihilator at 32x ore multiplier, every swing yields 32x the base Stone or Copper drop, which is a massive Drill Piece income boost compared to late-game planets with higher node HP.
For end-game players looking to rebuild Drill Piece reserves between major crafting pushes, Earth bursts are the most reliable strategy. A focused 30-minute Earth burst with an Astral Annihilator can yield 1-2 million Drill Pieces, which is enough to fund a significant reforge campaign.
Earth as a Reforge Testing Ground
Earth's low node HP makes it the ideal planet for testing reforge builds. Because every node breaks in 1-2 hits regardless of drill tier, the only thing that matters on Earth is the ore multiplier and the swing rate. This makes Earth a perfect test bench for new reforges — you can quickly compare two reforge variants without worrying about node HP differences masking the results.
Many end-game players use Earth to test their reforge rolls before committing to a bind. The 5-minute Earth test gives them a clear picture of whether a reforge is worth keeping, which saves them from binding a suboptimal drill across a rebirth cycle.
Drill Choice for Speedrunners
For players who are chasing the fastest possible Earth clear time, the optimal drill is not necessarily the highest-tier drill. Instead, it is the drill with the best combination of swing rate, ore multiplier, and movement speed. A perfectly rolled mid-game drill with high Drill Speed might outperform a stock Legendary drill on Earth because of the faster swing rate.
The optimal speedrun drill depends on your reforge results, but the general principle is that drill speed and ore multiplier matter more than damage on Earth. Players who prioritize these two stats in their reforges will see the best Earth clear times.
