Choosing the right drill for your current stage in Dig a Garden is crucial for efficient progression. This guide recommends the best drill for every stage from day one to end-game. Understanding the core loop—buying drills, placing them on your plot, digging up items, and selling them for Diglets—is only half the battle. The other half is knowing exactly which drill to invest in at each milestone to maximize your Diglets per hour and avoid wasting hard-earned currency on inefficient upgrades.
Whether you are a brand-new player just placing your first Starter Drill or a seasoned digger hunting for Legendary items, optimizing your drill loadout dictates your progression speed. Let us break down the best drill for each stage, complete with strategies, inventory management tips, and exact earn rates.
Early Game (0-20K Diglets)
Best drill: Group Drill (free, A-tier)
The Group Drill is the undisputed best early-game drill. Join The Heap group, claim it for free, and it doubles your early earnings compared to the Starter Drill alone.
| Drill | Tier | Cost | Diglets/Hour |
|---|---|---|---|
| Group Drill | A | Free | 18K-28K |
| Starter Drill | C | Free | 3K-6K |
Strategy: Place Group Drill + Starter Drill. Save for Standard Borer (~5K).
During this stage, your primary goal is establishing a baseline of passive income. The Starter Drill is given to you by default, but its 3K-6K Diglets/hour rate is extremely sluggish. By joining the game's official Roblox group, The Heap, you unlock the Group Drill for absolutely zero Diglets. This single action multiplies your early earning potential by up to 5x.
How-To Claim Your Free Group Drill:
- Open Roblox and navigate to the The Heap community page.
- Click the "Join Group" button.
- Launch Dig a Garden.
- Walk to the drill shop and select the Group Drill. The price will display as "Free" instead of the usual cost.
- Place it on your plot immediately alongside your Starter Drill.
While saving up for your first Standard Borer, focus on frequently selling your Common and Unusual items. Do not let your inventory fill up, as an full inventory halts your drills' digging operations entirely.
Mid Game (20K-100K Diglets)
Best drills: Turbo Digger + Deep Piercer (A-tier)
Mid game is about filling your plot with A-tier drills for maximum earnings:
| Drill | Tier | Cost | Best For |
|---|---|---|---|
| Turbo Digger | A | ~20K | Speed + frequent items |
| Deep Piercer | A | ~50K | Rare item hunting |
| Group Drill | A | Free | Fill remaining slots |
Strategy: Replace Standard Borers with Turbo Diggers first, then add Deep Piercers.
Once you cross the 20K Diglet threshold, you enter the mid-game. Here, the Standard Borer (B-tier) starts to show its limitations. While it was a solid upgrade from the Starter Drill, it lacks the speed to consistently generate Scarce items and the depth to hit Legendary nodes.
The Turbo Digger is your first major milestone. It digs significantly faster than the Standard Borer, ensuring your inventory fills with a higher volume of items. More items dug means more items sold. After securing two Turbo Diggers, pivot to saving for the Deep Piercer. The Deep Piercer sacrifices a bit of raw speed for depth, drastically increasing your chances of unearthing Scarce and Legendary items, which sell for massive amounts of Diglets.
During this phase, you must actively manage your inventory. Upgrading your inventory space is just as important as upgrading your drills. Check out our Inventory Cap Guide for a full breakdown, but the general rule is to always reinvest 10-15% of your earnings into expanding your bag so your drills never sit idle.
Late Game (100K+ Diglets)
Best drill: Mega Borer (S-tier, F2P)
The Mega Borer is the most impactful F2P upgrade in the game:
| Drill | Tier | Cost | Diglets/Hour |
|---|---|---|---|
| Mega Borer | S | ~100K | 35K-55K |
Strategy: Replace A-tier drills with Mega Borers one at a time as you can afford them.
Hitting 100K Diglets is a massive achievement. At this stage, the Mega Borer becomes available, and it completely shifts the economy of your plot. A single Mega Borer out-earns two Turbo Diggers combined. Because it hits S-tier status, it digs deeper and faster than any A-tier drill, consistently pulling Scarce items and frequently striking Legendary nodes.
The optimal strategy here is incremental replacement. Do not sell all your A-tier drills at once to buy one Mega Borer, as that temporarily kills your earning rate. Instead, save up 100K Diglets while your current drills work, buy one Mega Borer, place it, and then save for the next one. Slowly phase out your Turbo Diggers and Deep Piercers. Keep one Deep Piercer on your plot if you are specifically targeting a specific Legendary item for a quest, but otherwise, raw Diglet volume from the Mega Borer is king.
End Game (All S-tier)
Best setup: Full Mega Borers + optional Deep Piercers
| Goal | Setup | Earnings |
|---|---|---|
| Maximum Diglets | All Mega Borers | 35K-55K/hr per drill |
| Legendary Focus | Mix Mega Borer + Deep Piercer | Balanced |
| Premium | Galaxy + Mega Borers | Best of both |
At the end game, your plot is a well-oiled machine. F2P players will want a full plot of Mega Borers generating a staggering 35K-55K Diglets per hour per drill. If you are hunting specific high-value Legendaries to complete your collection or decorate your garden, swapping one Mega Borer for a Deep Piercer is a viable strategy, as the Deep Piercer's depth mechanic specifically targets the deepest, rarest item nodes.
Premium players who managed to acquire the Galaxy Drill before it went off-sale have a distinct advantage. The Galaxy Drill matches the Mega Borer's output but features unique visual effects and a slightly larger dig radius, allowing it to cover more ground on your plot.

Inventory Management and Offline Progression
One of the most critical mechanics in Dig a Garden is offline progression. Your drills will continue to dig while you are offline, which is fantastic for accumulating wealth passively. However, there is a major catch: if your inventory fills up while you are offline, your drills stop working.
This makes inventory management a core progression mechanic. If you log off for 8 hours with a nearly full inventory, you might only earn Diglets for the first hour. To maximize your Offline Earnings, you must balance your inventory capacity with your drills' output.
How-To Maximize Offline Earnings:
- Empty Your Inventory First: Always sell all items right before closing the game.
- Calculate Your Downtime: If your drills generate 100 items per hour and your inventory holds 400 items, you can safely go offline for 4 hours. For an 8-hour school or work day, you need an 800-item capacity.
- Upgrade Inventory Strategically: Use your Diglets to upgrade your inventory cap before buying that next expensive drill if you find yourself capping out frequently.
| Inventory Level | Capacity | Upgrade Cost (Diglets) | Recommended Stage |
|---|---|---|---|
| Level 1 | 100 | Free | Early Game |
| Level 2 | 250 | 2,000 | Early Game |
| Level 3 | 500 | 7,500 | Mid Game |
| Level 4 | 1,000 | 25,000 | Late Game |
| Level 5 | 2,500 | 75,000 | End Game |
Daily Progression Walkthrough
Consistency is key in Dig a Garden. A player who logs in three times a day for five minutes will progress much faster than a player who logs in once a day for an hour, purely because of inventory cap limitations. Here is an optimal daily routine for mid-to-late game players:
- Morning Login (5 mins): Log in, sell all items from overnight digging. Check if you have enough for your next drill upgrade. If yes, buy and place it. Log out.
- Afternoon Login (5 mins): Log in, sell all items. If you are actively saving for a Mega Borer, do not buy anything else. Let your Diglets accumulate. Log out.
- Evening Login (15 mins): Log in, sell all items. Spend this longer session organizing your plot, shifting drills to optimal positions, and participating in any active server events or drops. Do a final sell right before logging off for the night.
By following this loop, you ensure your drills are never blocked by a full inventory, and your Diglets compound continuously.
FAQ
Q: When should I move from early to mid game? A: When you can afford your first Turbo Digger (~20K Diglets). This marks the transition.
Q: Should I skip mid-game and save for Mega Borer? A: No. Each A-tier drill pays for itself within hours. Skipping tiers wastes potential earnings.
Q: How long does each stage take? A: Early: 1-2 days. Mid: 3-7 days. Late: 7-14 days. These timelines assume regular check-ins every 2-3 hours.
Q: What is the single most important drill upgrade? A: Claiming the free Group Drill. It is instant, free, and A-tier — the best early-game move you can make.
Q: What happens if my inventory fills up while I am at school or asleep? A: Your drills will stop digging entirely until you log back in and sell your items. This is why upgrading your inventory capacity is vital. Always sell your items right before logging off, and ensure your inventory cap can hold at least the number of items your drills will produce during your offline period.
Q: Is the Galaxy Drill ever coming back? A: The Galaxy Drill is currently off-sale and classified as a premium limited item. The developers at The Heap have not announced a re-release. Rely on the Mega Borer as the definitive end-game drill for F2P players, as its performance is nearly identical.
Q: Should I sell my old drills when upgrading? A: Yes, but only when you need the plot space. You do not get a refund of Diglets for selling a drill, so there is no financial benefit to removing a working drill unless you are replacing it with a better one immediately. Keep your old A-tier drills running on the edges of your plot until you have the exact funds to swap them out for S-tier Mega Borers.
