Drill to Earth's Core Tools Hub

This Tools hub is a pair of reference tables for Drill to Earth’s Core, the 30-player Roblox co-op descent that released on February 25, 2026. It is not an in-game calculator, loot simulator, upgrade planner, or Core converter. Nothing on these pages spends Cores, Coins, or Robux for you. You read a number, you go back to the shared drill, and you act on it with the rest of the server.

Two charts live here. The layer depth chart lists all twelve named layers with start and end depths, boss wall HP, threats, and named structures. The class cost chart lists every class with a verified Core price, the Level 4 team-bonus depth gates we have confirmed, the 2,500-Core passive reroll, and a short list of classes whose prices are still unverified. Same-category pages link to each other so you can jump from a wall HP to a class wallet without hunting the nav.

What these tables are for

A full server is loud. People shout depths, class names, and fuel warnings over each other while the vehicle is still chewing Dirt. A static table beats a half-remembered Discord screenshot. Pin the layer depth chart when you are driving. Pin the class cost chart when you are in the lobby Academy. That is the whole design: two pages, two jobs, no fake widgets.

Cores buy classes. Coins buy in-run drill upgrades. Those currencies do not mix, and a tools page that pretends they do will waste your wallet. If you still need the loop explained from spawn, start with Getting Started and come back here when you can name fuel, sacks, and the first dungeon without a tooltip.

How to use the depth chart on a live run

Call the next wall before you commit the drill. Grass through Stone is the teaching band: 100 HP, then 500, then 1,000. Clay at 24,000 m is the first run-killer because the Void Clay wall empties the entire fuel tank. Glowing Core starts at 84,000 m, and the 100 km wall sits at 500,000 HP. Heart of the Earth does not begin until 1,000,000 m. Pair those numbers with the 100 KM walkthrough so the table turns into a route instead of a trivia list.

When the wall HP jumps from 10,000 at Crystal to 25,000 at Toxic, the chart is telling you to open the upgrade tier list and stop dumping Common stacks into Power Drive. When Clay is 2,000 m away, the chart is telling you to restock coal even if the bar looks fine. The numbers do not drive the vehicle. They tell you when to stop being casual.

How to use the class chart before you spend Cores

Miner costs 100 Cores and is the only cheap unlock. After that, the usual paid follow-ups are Lucky Looter at 10,000 or Driller at 5,000. Pirate and Reaper are late wallets at 30,000 and 10,000. Rankings and playstyles live on the class tier list. The cost chart does not argue meta. It stops you from saving 3,000 Cores for a class that actually costs 10,000.

Level 4 on every class is a team bonus that helps the whole 30-player server. Most of those bonuses gate on career total depth, not a single run. Miner asks for 500,000 m accumulated. Several 5,000-Core classes ask for 5,000,000 m. That is why the class page lists depth gates next to prices: buying the role and finishing the bonus are different grinds.

What this hub will not do

It will not redeem promo codes, because place 101906032112547 has no redeem box. The codes hub stays empty on purpose. Lists you see elsewhere belong to Dig to Earth’s CORE!, a different Roblox game. Farm Cores from achievements, daily quests, chests, and the 10 you get per boss wall instead of hunting a paste field that does not exist.

It will not invent prices for Witch, Salvager, Gunsmith, Priest, Recruit, Racer, Nightcrawler, or Crafter. If the Academy does not show a number we have confirmed, the class cost chart says so. Guessing a cost is worse than leaving a blank.

Season 1 launched in September 2026. Patch text belongs on the updates hub and the Season 1 notes. This hub tracks two questions players ask in chat: how deep is the next wall, and how many Cores does that class cost. Call those numbers on voice. A 30-player drill moves when someone can quote Clay at 24,000 m and Lucky Looter at 10,000 Cores without opening the Academy mid-wall.
