Welcome to the definitive Dig a Garden tier list for 2026. This comprehensive ranking covers every drill and item in the game, from S-tier (the absolute best) to C-tier (starter level). Whether you are just starting out on your plot or looking to maximize your offline Diglet earnings, this guide breaks down exactly where to invest your hard-earned currency. Dig a Garden, developed by The Heap, has surged past 25.7 million visits with a 98.3% approval rating, largely thanks to its satisfying core loop: buy drills, place them on your plot, dig up items, and sell for Diglets. But knowing which drills to buy—and when to upgrade—is the key to progressing efficiently.
Evaluation Criteria
Our tier list uses four weighted criteria:
| Criterion | Weight | Description |
|---|---|---|
| Diglets Per Hour | 35% | Total Diglets earning efficiency |
| Legendary Drop Rate | 25% | Chance of finding rare items |
| Dig Speed | 20% | Item discovery frequency |
| Value for Cost | 20% | Return on investment |
These four pillars determine a drill's true worth in Dig a Garden. Diglets Per Hour is the most critical metric because it dictates your purchasing power for future upgrades. Legendary Drop Rate becomes increasingly vital in the late game, where selling a single Legendary item can outpace hours of Common item farming. Dig Speed affects how quickly your inventory fills up, which ties directly into Value for Cost—especially since offline progression stops once your inventory is full. A drill that fills your inventory too quickly with low-value items while you sleep is actually less efficient than a slower drill that yields higher-tier items. Understanding this interplay is essential for making smart investments on your plot.
Drill Tier List
S-Tier (The Absolute Best)
| Drill | Type | Specialty | Why S-Tier? |
|---|---|---|---|
| Galaxy Drill | Premium | Legendary Hunting | Highest legendary rate in game |
| Mega Borer | F2P | Max Diglets/Hour | Best F2P money-maker |
S-tier drills are the end-game options. The Mega Borer is the best F2P drill, while the Galaxy Drill is the premium choice for legendary hunters. The Mega Borer is the pinnacle of F2P grinding. It balances high dig speed with an exceptional Diglets/hour rate, making it the ultimate money-maker for players who don't want to spend Robux. On the other hand, the Galaxy Drill is the holy grail for collectors. Although it was premium and is currently off-sale, its Legendary Drop Rate is unmatched. If you own this drill, focus your gameplay on active farming sessions rather than offline accumulation, as you'll want to empty your inventory frequently to capitalize on its rare finds.
A-Tier (Strong Performers)
| Drill | Type | Specialty | Why A-Tier? |
|---|---|---|---|
| Deep Piercer | F2P | Rare Item Discovery | Best F2P legendary hunting |
| Turbo Digger | F2P | Fast Dig Speed | High item frequency |
| Group Drill | F2P | Free Group Perk | Amazing free value |
A-tier drills are excellent for mid-to-late game. The Group Drill is particularly notable because it is free and A-tier — the best value in the game. A-tier drills carry you through the mid-game and can even hold their own in the late game. The Deep Piercer is your bridge to S-tier; it's the best F2P option for specifically hunting Legendary and Scarce items. The Turbo Digger lives up to its name with blistering Dig Speed, but beware: its high frequency means your inventory will cap out fast during offline sessions. Always empty your inventory before logging off with this drill. The Group Drill is an anomaly—a completely free A-tier drill provided you join The Heap Roblox group. It outclasses the Standard Borer effortlessly and should be your very first 'upgrade' in the game.
B-Tier (Reliable Mid-Game)
| Drill | Type | Specialty | Why B-Tier? |
|---|---|---|---|
| Standard Borer | F2P | Reliable Mid-Game | Solid upgrade from Starter |
B-tier is serviceable but should be upgraded as soon as possible. The Standard Borer is your first real taste of progression. It offers a noticeable bump in Diglets Per Hour and Dig Speed over the Starter Drill, allowing you to accumulate wealth at a steady pace. However, it lacks the specialized stats to reliably drop Scarce or Legendary items, so treat it as a stepping stone to the Turbo Digger or Deep Piercer.
C-Tier (Starter Level)
| Drill | Type | Specialty | Why C-Tier? |
|---|---|---|---|
| Starter Drill | F2P | Starting Out | Replace ASAP |
C-tier drills are starting points only. Replace them with better drills as soon as you can afford upgrades. The Starter Drill is exactly what it sounds like. It digs up Common items almost exclusively and generates minimal Diglets. Use it just long enough to afford the Standard Borer, or better yet, join The Heap group immediately to claim the Group Drill for free and skip this tier entirely.
Item Rarity Tier List
S-Tier (Legendary)
- Ultra-rare items worth massive Diglets
- Found primarily by Deep Piercer and Galaxy Drill
These are the items that fund your end-game drill purchases. Found primarily by the Deep Piercer and Galaxy Drill, Legendary items often feature unique visual effects when dug up. Because of their massive sell value, finding just one can cover the cost of an entire mid-game drill upgrade. They are the ultimate prize for active players.
A-Tier (Scarce)
- Rare items worth high Diglets
- Found by A-tier and S-tier drills
Scarce items form the backbone of a profitable late-game inventory. Drills like the Deep Piercer and Turbo Digger will dig these up regularly. A full inventory of Scarce items yields significantly more Diglets than a full inventory of Unusual items, making inventory space highly valuable when using higher-tier drills.
B-Tier (Unusual)
- Uncommon items worth moderate Diglets
- Found by Standard Borer and better
These start appearing once you upgrade to the Standard Borer. While they won't make you rich overnight, they provide a comfortable income stream that accelerates your path to A-tier drills. They are the benchmark where you start seeing real progression in your Diglet count.
C-Tier (Common)
- Frequent items worth low Diglets
- Found by all drills
Found by all drills, these are the bread and butter of the early game. The problem with Common items isn't their individual value, but how quickly they fill up your inventory. If your inventory fills with Commons while you're offline, you lose out on potential Scarce or Legendary drops, effectively halting your progression.
Offline Progression and Inventory Management
One of the most critical mechanics in Dig a Garden is offline progression. Your drills continue to dig even when you are not actively playing, but there is a hard cap: your inventory. Once your inventory is full, your drills stop working. This makes inventory management just as important as the drills themselves. Upgrading your inventory space is arguably as vital as upgrading your drill. If you log off for eight hours with a small inventory, you might only earn Diglets for the first two hours before your plot shuts down.
Understanding how inventory caps interact with drill speed is vital. Fast drills like the Turbo Digger will fill a base inventory incredibly fast, making them poor choices for overnight farming unless you have heavily invested in inventory expansions. Slower, high-value drills like the Deep Piercer are often better for offline play because they pull fewer low-value items, leaving room for occasional high-tier drops.
| Upgrade Level | Capacity | Cost (Diglets) | Recommended Drill Tier |
|---|---|---|---|
| 1 (Base) | 50 | Free | C-Tier |
| 2 | 100 | 500 | B-Tier |
| 3 | 250 | 2,500 | A-Tier |
| 4 | 500 | 10,000 | A-Tier / S-Tier |
| 5 (Max) | 1,000 | 50,000 | S-Tier |
If you are using a Turbo Digger (A-Tier) with a base inventory of 50, you will cap out in under an hour of offline play. Always prioritize upgrading your inventory to at least Level 3 before investing heavily in A-tier drills. For S-tier drills like the Mega Borer, a Level 4 or 5 inventory is essential to maximize overnight earnings.

How to Progress Quickly — A Step-by-Step Walkthrough
Understanding the tier list is only half the battle; applying it efficiently is what separates casual gardeners from Diglet millionaires. Follow this walkthrough to optimize your progression from your first dig to end-game wealth.
Step 1: The Free Upgrade When you first spawn, don't even think about buying the Standard Borer. Instead, immediately join The Heap Roblox group and claim the free Group Drill. This instantly propels you from C-Tier to A-Tier, skipping the entire early-game grind. Place the Group Drill on your plot and start digging immediately.
Step 2: Inventory First Use the Group Drill to farm Diglets, but do not buy a new drill yet. Spend your first 2,500 Diglets on the Level 3 Inventory upgrade. This ensures you can leave the game overnight without capping out your earnings. A larger inventory acts as a multiplier for your drill's Diglets Per Hour.
Step 3: The Specialization Choice Once you have 10,000+ Diglets, choose your path. If you want steady money to buy the Mega Borer, purchase the Turbo Digger. If you want to gamble on high-value drops to fast-track your wealth, buy the Deep Piercer. You can learn more about this choice in our Drill Specialization Guide.
Step 4: The F2P Endgame Save up for the Mega Borer. Sell everything you dig up. Once you acquire the Mega Borer, immediately upgrade your inventory to Level 4 or 5. You are now in the end-game, capable of generating massive amounts of Diglets both actively and offline.
F2P vs Premium: The Ultimate Drill Showdown
The debate between the Mega Borer (F2P) and the Galaxy Drill (Premium) is the most discussed topic in the Dig a Garden community. While both sit comfortably in S-Tier, they serve entirely different purposes and cater to different playstyles.
| Feature | Mega Borer (F2P) | Galaxy Drill (Premium) |
|---|---|---|
| Acquisition | In-game purchase | Off-sale (was Robux) |
| Best For | Diglets/Hour | Legendary Item Hunting |
| Offline Efficiency | High (with large inventory) | Low (caps fast with high value) |
| Active Play Value | Moderate | Extremely High |
| Overall Versatility | High | Specialized |
The Mega Borer is the undisputed king of offline Diglet generation. If your goal is to accumulate raw wealth to buy every item in the game, this is the drill to use. The Galaxy Drill, conversely, is an active player's dream. Its legendary drop rate means that every time you hear the dig sound, there's a higher chance you've struck gold. However, because high-tier items fill inventory value quickly, it requires constant babysitting. For a deeper dive, check out our F2P vs Premium Analysis.
FAQ
Q: How often is this tier list updated? A: We update after every major patch and balance change. The current rankings are accurate as of July 2026.
Q: Can I trust community tier lists? A: Community tier lists are generally more reliable than developer descriptions for drill rankings, as they reflect actual in-game performance data.
Q: What if a new drill is added? A: New drills will be evaluated and added to the tier list as soon as community data is available. Check back after game updates.
Q: Are there underrated drills? A: The Group Drill is often underrated but is genuinely A-tier and free. It is the best early-game value by far.
Q: Does offline progression continue indefinitely? A: No. Offline progression stops the moment your inventory fills up. If you have a small inventory and a fast drill, you might stop earning after just a few hours offline. Upgrade your inventory capacity to maximize overnight gains.
Q: How do I claim the free Group Drill? A: Simply join The Heap Roblox group linked in the game description, restart the game, and the Group Drill will be available in your inventory for free. This is the single most important step for a new player.
Q: Should I sell Common items or wait for better ones? A: Always sell your inventory before logging off, regardless of item rarity. Holding onto items provides no benefit, and a full inventory prevents your drills from digging up potentially better items while you are away. Active selling is the key to wealth.
