All 21 Drill Upgrades in Drill to Earth's Core

Drill upgrades are the purchases that make the drill stronger as you go. They can raise how hard your drill hits walls and enemies, how fast it moves, how much it can carry and how well your team holds up on the way down. Knowing how they're bought and which ones are worth your Coins can make a real difference to how far you get.

How Drill Upgrades Are Bought

Drill upgrades are bought at the Trading Post upgrade menu using Coins. You earn Coins by selling the loot you dig up at checkpoints, so the more you collect and sell, the more you can spend. Each time you open the menu, you pick from a set of upgrade cards. Upgrades go on the shared drill rather than your character, so the whole team benefits from each one you buy.

Drill Upgrade Tiers and Prices

Each purchase raises the cost of later upgrades, so keep enough Coins for the cards your team needs.

That's why the tiers matter for timing as well as cost. Commons are the cheapest to start with, so they're the usual early buy, while the pricier tiers make more sense once your Coin total has grown.

Best Drill Upgrades to Buy First

Drill Power is the best first pick for most players. It raises the damage your drill does to walls, and the walls get harder the deeper you dig, so a drill that falls behind on damage slows you down quickly. Runs tend to end in one of three ways: you run out of money, your drill can't get through the walls, or your health runs out. Good picks help with at least one of those.

Power Burst and RPM Overclock are the other top picks for damage and progress. On the survival side, Health Regen stands out and pays off even at its first level, while Team Health is a solid and cheaper companion.

How to Get a Free Drill Upgrade

The Executioner class gives your team a free drill upgrade each time it defeats a boss, once the class reaches its Level 4 team perk. You choose from three options each time, so it's a steady source of upgrades that doesn't cost Coins. Those free picks add up quickly if your team takes on bosses often.
