Tectonic Industries Drill Tier List Overview
The Tectonic Industries drill tier list ranks all 14 drills in the game from worst to best based on mining speed, depth access, and overall utility. Drills are the backbone of your mining operation, and choosing the right ones to invest in can make or break your factory's efficiency. This guide ranks every drill so you know exactly where to spend your resources.
In Tectonic Industries, drills are categorized into four tiers: C, B, A, and S. The tier directly corresponds to mining power and the depth at which the drill can operate. Understanding this Tectonic Industries drill tier list is essential for planning your progression from BP1 to BP13.
S Tier - The Best Drills in the Game
The Tectonic Industries S tier drills are the most powerful mining machines available. These drills dominate endgame content and can access the rarest ores at the deepest levels.
| Drill | Blueprint | Mining Speed | Depth Access | Why S Tier |
|---|---|---|---|---|
| Lead | BP13 | Maximum | Deepest | Best drill in the game, mines everything |
| Cobalt | BP12 | Very High | Very Deep | Mines cobalt ore and all rare materials |
| Chromium | BP12 | Very High | Very Deep | Chromium extraction, matches Cobalt power |
The Lead Drill earns the top spot on the Tectonic Industries drill tier list because it is the only drill that reaches maximum depth and mining speed. Cobalt and Chromium share the BP12 blueprint level, meaning you can unlock two S-tier drills at the same milestone.
A Tier - Advanced Drills Worth Building
A-tier drills represent a major step up from B-tier and are essential for accessing deep-level ores and special resources. The Tectonic Industries drills ranked in A tier are your bridge to the endgame.
| Drill | Blueprint | Mining Speed | Depth Access | Why A Tier |
|---|---|---|---|---|
| Oil Pump | BP11 | High | Surface (Oil) | Only source of Oil in the game |
| Sulfur | BP10 | High | Deep | Sulfur extraction for advanced recipes |
| Tin | BP9 | High | Deep | First A-tier drill, unlocks deep mining |
The Tin Drill at BP9 is particularly notable because it is your first access point to deep-level mining. The Sulfur Drill at BP10 continues this trend, while the Oil Pump at BP11 provides a unique resource that no other drill can produce.
B Tier - Solid Mid-Range Options
B-tier drills carry you through the mid-game and provide reliable mining for common and uncommon ores. While they eventually get outclassed by A and S tier, they are cost-effective for their blueprint level.
| Drill | Blueprint | Mining Speed | Depth Access | Why B Tier |
|---|---|---|---|---|
| Granite | BP8 | Medium-High | Mid-depth | Granite processing for construction |
| Zinc | BP7 | Medium-High | Mid-depth | Zinc for alloy production |
| Gold | BP6 | Medium-High | Mid-depth | Gold mining for currency and crafting |
| Silver | BP5 | Medium | Mid-depth | Silver ore for mid-game recipes |
| Iron | BP4 | Medium | Mid-depth | Iron production, first B-tier drill |
The Iron Drill stands out among B-tier Tectonic Industries drills ranked because it represents the first real upgrade from starter equipment. Gold and Zinc drills are also valuable for their respective ores used in Refiners and Forges.
C Tier - Starter Drills (Replace ASAP)
C-tier drills are your starting equipment. They get the job done early on but should be replaced as quickly as possible with B-tier drills and beyond.
| Drill | Blueprint | Mining Speed | Depth Access | Why C Tier |
|---|---|---|---|---|
| Coal | BP3 | Low | Shallow | Coal mining, basic fuel source |
| Copper | BP2 | Low | Shallow | Copper extraction for early crafting |
| Stone | BP1 | Baseline | Shallow | First drill, extremely basic |
These drills are functional but limited. The Stone Drill is literally the starting drill with baseline performance. Copper and Coal drills offer slight improvements but cannot access mid-depth or deep ores. Once you reach BP4 and unlock the Iron Drill, retire these C-tier drills.
Drill Tier List Summary Rankings
Here is the complete Tectonic Industries drill tier list from best to worst:
- Lead Drill (S Tier, BP13) - The undisputed king
- Cobalt Drill (S Tier, BP12) - Endgame powerhouse
- Chromium Drill (S Tier, BP12) - Endgame powerhouse
- Oil Pump (A Tier, BP11) - Essential for Oil
- Sulfur Drill (A Tier, BP10) - Deep mining specialist
- Tin Drill (A Tier, BP9) - Deep mining entry point
- Granite Drill (B Tier, BP8) - Solid mid-range
- Zinc Drill (B Tier, BP7) - Solid mid-range
- Gold Drill (B Tier, BP6) - Solid mid-range
- Silver Drill (B Tier, BP5) - Solid mid-range
- Iron Drill (B Tier, BP4) - First real upgrade
- Coal Drill (C Tier, BP3) - Basic fuel miner
- Copper Drill (C Tier, BP2) - Slight upgrade over Stone
- Stone Drill (C Tier, BP1) - Starting drill
Tips for Using This Tier List
- Do not skip B-tier drills. Even though S-tier drills are the goal, B-tier drills are your workhorses through the mid-game. Build them and use them well.
- Prioritize the Oil Pump. Oil is required for many advanced recipes and the Oil Pump is the only way to get it. Move this up your priority list.
- Cobalt and Chromium share BP12. You can unlock both Tectonic Industries S tier drills at the same blueprint level, making BP12 a huge milestone.

FAQ
Q: What are the Tectonic Industries S tier drills? A: The S tier drills are Cobalt (BP12), Chromium (BP12), and Lead (BP13). These are the most powerful drills in the game with the highest mining speeds and deepest depth access.
Q: Should I skip C-tier drills entirely? A: You cannot skip the Stone Drill since it is your starting equipment. However, you can minimize time spent on C-tier drills by progressing to the Iron Drill (BP4) as quickly as possible.
Q: Which A-tier drill should I build first? A: Build the Tin Drill (BP9) first since it is the lowest blueprint level A-tier drill and unlocks deep mining. Then progress to Sulfur (BP10) and Oil Pump (BP11).
Q: Is there a difference between Cobalt and Chromium drills? A: Both are S-tier drills at BP12 with very high mining speed and very deep access. The main difference is the primary ore each extracts. Build both for complete coverage.
Q: How often does the tier list change? A: The tier list may change with game updates from SeenVerge. Follow the YouTube channel and Discord for patch notes and balance changes.
Common Mistakes When Following the Tier List
Players often misapply tier list rankings in ways that hurt their progression:
-
Ignoring C-tier drills entirely - While C-tier drills are weak, they are necessary for blueprint progression. You must unlock BP1 through BP3 to reach B-tier. Rush through C-tier, but do not skip it.
-
Chasing only S-tier drills - S-tier drills are the goal, but B-tier and A-tier drills are your workhorses for the majority of the game. Neglecting mid-tier drills to save for S-tier means you have no income source while you grind for BP12.
-
Retiring B-tier drills too early - Even after you unlock S-tier drills, B-tier drills still produce valuable common and uncommon ores at mid-depth. Keep them running alongside your S-tier drills for diversified ore production.
-
Not building the Oil Pump because it is "only A-tier" - The Oil Pump may be A-tier, but it is the only source of Oil. No S-tier drill can produce Oil. This makes the Oil Pump more essential than some S-tier equipment.
-
Building only one BP12 drill - Both Cobalt and Chromium unlock at BP12. Building only one limits your very deep mining capability since each produces a different rare ore.
Pro Tips for Using the Drill Tier List
-
Use this tier list as a roadmap, not a rulebook - The tier rankings reflect overall power, but your specific factory needs may differ. If your forges need more Zinc, a B-tier Zinc Drill might be more valuable to you right now than an A-tier Sulfur Drill.
-
Invest in drills that fill gaps in your production - Check which ores your refiners and forges need, then prioritize drills that produce those ores. A balanced factory is more profitable than one with only S-tier drills mining the same ore.
-
Stack drills within the same tier - Two Iron Drills produce twice as much Iron. Three Gold Drills triple your Gold output. Multiple mid-tier drills can out-produce a single high-tier drill for specific ores.
-
Track your total mining output - The best way to evaluate your drill setup is to measure total income. If upgrading from Silver to Gold does not noticeably increase your income, your bottleneck may be elsewhere (refiners, forges, or depth access).
-
Check the Discord and YouTube for meta changes - Game updates from SeenVerge can shift the tier list. Follow the Discord and YouTube for the latest balance information.
Drill Tier List Quick Reference
For players who want a fast reference, here is the abridged tier list with key takeaways:
| Tier | Drills | Key Takeaway |
