Drill Tier List
Introduction
The drill tier list ranks every craftable drill head in Mine a Planet from Common through Legendary. Damage and ore multiplier formulas are derived from community mining data, and recommended planets are listed for each drill so you know exactly where each head shines. Use this page as a reference whenever you decide what to craft next. The tier list groups drills into S, A, B, and C tiers based on damage output, ore multiplier, and the highest planet the drill can clear with full durability. Damage scales with prestige points from Rebirths, so the same drill performs differently for a player who has done five Rebirths versus a player on their first run. Recommended planets are listed for each drill so you know exactly where each head shines. Use this page as a reference whenever you decide what to craft next.

Drill Breakdown
Mythril Destroyer
Mid-game legendary drill — required to clear the Nebula biome with full ore multiplier. Mid-game legendary drill — required to clear the Nebula biome with full ore multiplier. The Mythril Destroyer combines 450 base damage with x4.5 ore multiplier and is the first drill most endgame miners craft. Stockpile 50 Mythril Ore plus 25 Stardust before smelting the Mythril Bar prerequisite since Stardust only drops inside Nebula.
Cosmic Reaper
Top-tier legendary drill — the highest ore multiplier in the game but the most expensive to craft. Top-tier legendary drill — the highest ore multiplier in the game but the most expensive to craft. The Cosmic Reaper requires 100 Void Shards plus 50 Stardust to forge the Cosmic Core prerequisite, so plan for several Nebula farming sessions. Pair it with the Cosmic Wolf pet to push Void Shard drop rates to their practical maximum and clear Void runs in record time.
Solar Flare
Strong mid-game pick — pairs especially well with the Magma Piercer for high heat resistance. Strong mid-game pick — pairs especially well with the Magma Piercer for high heat resistance. The Solar Flare deals 320 base damage with a x3.0 ore multiplier, sitting comfortably between the Titanium Spire and the Legendary endgame. The recipe requires 30 Magma Ore plus 20 Titanium, both abundant after the Mars Deep phase of your progression.
Titanium Spire
Reliable mid-game drill — the first drill that lets you push into Mars Deep without losing durability. Reliable mid-game drill — the first drill that lets you push into Mars Deep without losing durability. The Titanium Spire deals 210 base damage and multiplies ore returns by x2.1, which is more than enough to clear Mars Deep comfortably. The recipe costs 20 Titanium Ore plus 10 Coal, achievable after a single Mars Deep farming session.
Iron Hammer
First mid-game drill — clears Mars comfortably and unlocks Europa with steady durability. First mid-game drill — clears Mars comfortably and unlocks Europa with steady durability. The Iron Hammer deals 160 base damage with a x1.6 ore multiplier, which is plenty for the Mars grind. The recipe costs 10 Iron Ore plus 5 Coal and unlocks as soon as you smelt your first Iron Alloy. Reforge this drill before your first Rebirth to keep it across the prestige reset.
Core Mechanics
The drill tier list sorts every drill into S, A, B, and C tiers based on damage output, ore multiplier, and the highest planet it can clear with full durability. Damage scales with prestige points from Rebirth, so a reforged Mythril Destroyer outscores a fresh Astral Annihilator even though both start in the S tier.

Damage scales with prestige points from Rebirth, so a reforged Mythril Destroyer outscores a fresh Astral Annihilator even though both start in the S tier. The tier list is re-verified within 48 hours of every major balance patch, so the numbers here should be current for the July 23, 2026 patch state. Treat the list as a guideline and verify with a small mining session before committing materials.
Advantages
A clear tier list makes crafting decisions fast — you always know which drill to forge next without comparing every stat manually. The list also flags which drills are worth reforging across Rebirths and which are throwaway mid-game picks. S-tier drills are guaranteed to scale into the endgame, so investing in one early saves smelter batches later.

Challenges
The tier list assumes a player who has unlocked every planet and smelted every alloy — beginners cannot use S-tier drills immediately. Some drills also have situational value (Quantum Borer shines on Europa but underperforms on Nebula) that a flat tier ranking cannot fully capture. Treat the list as a guideline rather than a strict rule, and verify damage with a small mining session before committing materials.

Quick Tips
Always reforge your strongest Rare drill before your first Rebirth — without reforging, your best drill resets to Common and your damage drops by half. Without reforging, your best drill resets to Common and your damage drops by half. Stockpile five Mythril Bars ahead of time so the reforge cost is covered the moment you reach level 25. The reforge is done at the Crafting Bench and preserves one drill of your choice across the reset. Always reforge your strongest Legendary drill rather than a mid-tier pick.
Carry one mid-tier and one legendary drill in your inventory. Swap to the mid-tier drill for low-durability grinds to save legendary repair kits. Repair kits cost 25 Drill Pieces each at the lobby vendor and add up quickly across a long grinding session. Carrying a mid-tier drill for low-durability grinds saves legendary repair kits for the highest-yield biomes. The savings typically add up to 30-40% less repair kit usage across a single 90-minute grinding session on a tier-2 biome like Europa.
Solar Flare pairs better with Magma Piercer than with Mythril Destroyer because both Epic drills share the same heat-resistance buff that stacks on Volcano. Both Epic drills share the same heat-resistance buff that stacks on Volcano. The damage bonus from the buff is larger than the raw multiplier difference between Epic and Legendary drills on that biome. Pair them for the highest effective damage on Volcano, and switch back to the Mythril Destroyer for the Nebula and Void biomes where the heat-resistance buff does not apply.
