Mine a Planet C-Tier Drills: Wooden Pickaxe & Copper Drill

The Mine a Planet C-tier drills are the three Common-tier crafts — Wooden Pickaxe, Copper Drill, and Stone Breaker — that form the starter progression for new players. These drills are designed to be replaced quickly, and most players will only use each one for a few hours before moving to the next tier. This tier list page covers each C-tier drill, the recommended use cases, and when to replace each one.

For the complete tier list including S, A, and B tiers, see our Mine a Planet S-tier drill list. For the early-game progression strategy, see our Mine a Planet beginner guide. This principle applies broadly across all progression stages and is one of the most reliable optimization levers in the game.

C-Tier Drill Overview

The three C-tier drills are the simplest crafts in the game. The Wooden Pickaxe is the starter drill given to every new player, and the Copper Drill and Stone Breaker are the first two crafts available at the crafting bench. None of these drills persist into the mid-game progression, but they are essential for the first few hours of play.

The damage scaling between C-tier drills is roughly 50% per tier, which makes each upgrade a meaningful improvement during the early game. The ore multiplier scaling is smaller, but it compounds with every swing to deliver noticeable Drill Piece income gains.

Wooden Pickaxe Deep Dive

The Wooden Pickaxe is the starter drill and the lowest-tier drill in the game. Every new player receives one for free when they spawn in, and it has roughly 30 base damage with a 1x ore multiplier. The drill is designed to be replaced within the first hour of play.

The Wooden Pickaxe's only meaningful use case is the tutorial — it breaks the lowest-HP Earth nodes in 3-4 hits, which is just enough to let new players learn the mining loop. After the first craft (the Copper Drill), the Wooden Pickaxe should be discarded from your active loadout.

The Wooden Pickaxe can be reforged for practice — the reforge cost is essentially free, which makes it a useful training tool for learning the stat pool. But it should never be bound across a rebirth or used for any serious grinding.

Copper Drill Deep Dive

The Copper Drill is the first craftable drill and the first meaningful upgrade over the Wooden Pickaxe. It requires 10 Common Ingots plus the prerequisite Common bench upgrade, and it is the natural first craft for new players. The exact mechanics vary slightly by patch, but the underlying principle remains consistent across all player playstyles.

The Copper Drill has roughly 60 base damage and a 1.5x ore multiplier. The damage is enough to break Earth nodes in 2-3 hits, which is the sweet spot for early-game grinding. The ore multiplier is a 50% boost over the Wooden Pickaxe, which compounds into noticeable Drill Piece income gains over an hour of play.

The Copper Drill is the recommended bind for new players who are doing their very first rebirth and have not yet crafted any Rare-tier drills. The Prestige Point payout is low compared to higher-tier binds, but it is meaningful for first-time rebirths.

Stone Breaker Deep Dive

The Stone Breaker is the second craftable Common-tier drill and the strongest drill in the C-tier. It requires 15 Common Ingots plus the prerequisite Common bench upgrade, and it is a meaningful upgrade over the Copper Drill. Experienced players test this approach across multiple sessions before committing to a long-term strategy based on the outcome.

The Stone Breaker has roughly 90 base damage and a 1.75x ore multiplier. The damage is enough to break Earth nodes in 2 hits with a fresh craft, which makes it the fastest Common-tier drill for early-game grinding. The ore multiplier is the highest of any C-tier drill.

The Stone Breaker is the recommended bind for new players who have not yet pushed to the Iron Hammer. It grants slightly more Prestige Points than the Copper Drill and provides better performance during the Earth grinding phase. Combining this insight with active pet bonuses and prestige multipliers yields compounding benefits that accelerate overall progression.

When to Replace C-Tier Drills

The replacement timing for each C-tier drill is determined by the next planet unlock requirement, not by an arbitrary timer. The recommended replacement order is Wooden Pickaxe → Copper Drill (after crafting) → Stone Breaker (after crafting) → Iron Hammer (after unlocking Mars).

Players who hold on to C-tier drills beyond their replacement window waste hours of grinding time on lower-HP nodes that yield less Drill Piece income than the higher-tier alternatives. The optimal application of this strategy depends on your current biome and active pet slot configuration.

Frequently Asked Questions

Is the Wooden Pickaxe ever useful after the tutorial?

Only for reforge practice. The Wooden Pickaxe reforge cost is essentially free, which makes it a useful training tool for learning the reforge system without risking Drill Pieces. Yes, this item is valuable at every stage because it provides a permanent bonus that compounds with other systems.

Should I bind a C-tier drill across my first rebirth?

Only if you have not yet crafted any higher-tier drill. Binding a C-tier drill grants the minimum Prestige Points, so it is a missed opportunity if you have any Rare or Epic drill available. Generally yes, but the optimal timing depends on your current resource reserves and your active biome's node HP profile.

What is the best C-tier drill for sale on the trade market?

The Stone Breaker has the highest trade value of the three C-tier drills because of its higher damage and ore multiplier. Stone Breakers typically sell for 5,000-15,000 Drill Pieces. Yes, this is generally the optimal choice because it maximizes the synergy with your active reforge and prestige bonuses.

Can I skip the Stone Breaker and go straight to the Iron Hammer?

Yes, you can skip the Stone Breaker. The Stone Breaker is not a prerequisite for the Iron Hammer, only the prerequisite Common bench upgrade is required. Yes, but the optimal approach depends on your current progression stage and your stockpile of supporting materials.

How long should I use each C-tier drill?

The Wooden Pickaxe should be used for less than an hour, the Copper Drill for roughly 1-2 hours, and the Stone Breaker for 2-4 hours. The exact timing depends on your grinding efficiency and how quickly you stockpile Common Ingots.

C-Tier Drills for Alt Accounts and Trade-Focused Players

While most main-account players skip past C-tier drills as quickly as possible, there are two scenarios where C-tier drills remain valuable. First, alt accounts that have just been created will go through the entire C-tier progression on their way to unlocking Mars. The C-tier drills are the only option for these accounts during the first few hours of play. Second, trade-focused players sometimes stockpile C-tier drills for bulk sale to new players, particularly during major events when new players flood the game.

For both use cases, the Stone Breaker is the most valuable C-tier drill because of its higher damage and ore multiplier. New players who buy a Stone Breaker from the trade market save 2-4 hours of Common Ingot grinding compared to starting from the Wooden Pickaxe.

The C-Tier to B-Tier Transition Point

The transition from C-tier to B-tier is the most dramatic damage jump in the early game. Going from the Stone Breaker (90 damage) to the Iron Hammer (280 damage) is roughly a 3x damage increase, and the ore multiplier jumps from 1.75x to 2.5x. The transition takes roughly 4-6 hours of focused Earth grinding to stockpile the Iron Alloy materials, and most players feel a meaningful improvement in grind efficiency the moment they equip the Iron Hammer.

When to Skip the Stone Breaker Entirely

Some experienced players skip the Stone Breaker entirely and go directly from the Copper Drill to the Iron Hammer. The reasoning is that the Stone Breaker's 90 damage is only marginally better than the Copper Drill's 60 damage, and the 2-4 hours of grinding to craft the Stone Breaker could instead be spent stockpiling Iron Alloy materials for the Iron Hammer. This is a viable strategy for players who already know the game well, but it is not recommended for brand-new players who should experience the full progression.

Why C-Tier Drills Have Low Reforge Returns

Even though the Wooden Pickaxe reforge is essentially free, the maximum stat rolls on C-tier drills are significantly lower than on Rare or Legendary drills. A perfectly rolled Wooden Pickaxe will never match a perfectly rolled Copper Drill on any stat, which means reforging C-tier drills is mostly a learning exercise rather than a meaningful progression strategy.

For players who want to learn the reforge system, the Wooden Pickaxe is the ideal training drill. For players who want meaningful reforge returns, save your Drill Pieces for Rare or Legendary reforges. The C-tier reforge cost is low but the returns are correspondingly low.

Common C-Tier Mistakes

The most common mistake new players make with C-tier drills is to reforge the Wooden Pickaxe repeatedly looking for a "perfect roll" that does not exist within the C-tier stat pool. The maximum Wooden Pickaxe ore multiplier is roughly 1.3x, which is lower than the Copper Drill's base 1.5x. No amount of reforging will close that gap.

The second mistake is to bind a C-tier drill across the first rebirth without crafting any higher-tier drill. The Prestige Point payout for a C-tier bind is the lowest in the game, and missing out on a Rare or Legendary bind is a meaningful opportunity cost. Always push to the highest-tier drill available before triggering your first rebirth.
