Core Keeper Drill Guide

#Direct Answer

Use a Drill when you have found an ore boulder that deserves repeat mining. A Drill is crafted at the Automation Table with Iron Bars and Scarlet Bars, then powered by electricity so it can work against the boulder over time.[1] One drill can start the setup, but current community wiki data notes that one to eight drills can work on a single boulder, with more drills increasing ore production speed at diminishing returns.[2]

The practical first setup is simple:

1. mark the ore boulder
2. clear space around it
3. place a Drill facing the boulder
4. connect power from an Electricity Generator
5. collect the ore manually or route it with conveyors later

Do not start with a huge factory. Prove the boulder is useful, then expand.

#Scene Check

A good drill setup is readable before it is clever: boulder face, powered drill, output space, and a return plan.

#What A Drill Actually Solves

Drills are for repeat ore value, not for every mining problem. The Drill page describes drills as technology and automation items that can slowly drill tougher materials such as ore boulders when powered by electricity.[1]

That makes them best when:

• you found a Copper, Tin, Iron, Scarlet, Octarine, Galaxite, or later ore boulder
• the boulder is close enough to revisit
• the ore tier still matters for upgrades
• you can afford the setup without stalling the current route
• you want passive supply over time instead of one manual haul

If you only need a small amount of ore right now, mining veins may be faster. If you need the same ore repeatedly, the drill setup starts paying back.

#The Minimum Drill Setup

For a first rig, keep it boring.

You need:

• an ore boulder
• at least one Drill
• an Electricity Generator or powered line
• space behind the drill for dropped ore
• a clear marker so you can find the setup again

The Electricity Generator page lists it as an electronics item that powers wires and objects with electricity, crafted at the Electronics Table from Copper Bars.[3] That matters because many failed first drill setups are not really drill problems. They are power problems.

#What A Worthwhile First Drill Setup Usually Looks Like

The first drill rig is good when it quietly saves future time.

That usually means:

• the boulder is close enough that revisiting it feels natural
• the ore tier still matters for current upgrades
• the drill direction is obvious and easy to test
• power is simple enough that you can tell whether the setup is live
• the area is clear enough that collection does not become its own problem

If the setup takes longer to understand than the ore would save, the rig is probably too ambitious for the current need.

#How Many Drills Should You Use?

Start with one drill when you are learning the layout. Add more only when the boulder is worth speeding up.

The wiki notes that more drills improve ore production speed with diminishing returns.[2] In practical terms, that means the eighth drill is not as meaningful as the first drill. Do not spend rare bars just to make a low-priority boulder look complete.

#Manual Collection Is Fine At First

You do not need conveyors, robot arms, or automatic smelting immediately. The Drill page notes conveyor behavior and advanced automation possibilities, but those are second-step improvements.[1]

Manual collection is fine when:

• the boulder is near a normal route
• you only need a small supply buffer
• the ore is not feeding constant crafting
• you are still learning power placement

Add conveyors when the boulder is far enough, productive enough, or important enough that manual pickups feel wasteful.

#Build One Honest Drill Before Expanding

Many automation setups go wrong because players build the big version before the small version has ever proven itself.

The first honest test should be:

1. one powered drill
2. one boulder that still matters
3. one clean output space
4. one revisit to confirm ore actually is dropping as expected
5. one reason the ore helps the next real project

If that test feels awkward, debug the small rig first. Do not add more drills, wires, or conveyors until the boring version already works.

#What A Good First Drill Session Looks Like

A good first drill session should prove the boulder is worth the setup.

Use this pattern:

1. mark the boulder before building
2. place one drill facing the correct side
3. connect simple power and confirm it is live
4. revisit once to check ore output
5. expand only if the boulder still matters to the save

If the first rig already needs a large conveyor rebuild, the setup is probably too ambitious for the current need.

#What A Normal Drill Setup Should Leave You With

A useful first drill project should leave you with one calm passive ore answer, not a giant automation chore list.

It usually means:

• one powered boulder that is easy to relocate on the map
• one clear reason the ore still matters to the current save
• one output area that does not need constant babysitting
• one honest answer about whether more drills are worth the bars
• less temptation to mine the same ore by hand every trip

If the setup is live but the next revisit still feels annoying, the problem is probably route comfort or layout, not drill count.

#When A Drill Setup Is Not Worth It

Skip the setup for now if:

• the ore tier is already obsolete
• the boulder is far from every useful route
• you cannot safely revisit the area
• the setup cost would delay a better upgrade
• you only need a one-time craft

This is where the drill guide connects to the broader ore-boulder decision. If the question is whether to remove, mark, or save the boulder, use the ore-boulder page first. If the answer is "use it," this page explains the setup.

#Common Drill Mistakes

Most drill problems are really setup-discipline problems.

Avoid these mistakes:

• placing the drill without confirming the facing
• forgetting power and assuming the drill is broken
• automating collection before the small rig proves useful
• overspending on a low-priority boulder
• leaving the area unmarked and then losing the setup on the map

#Stop Upgrading The Rig When The Ore Stops Owning The Save

A common waste pattern is continuing to perfect the drill area after the ore itself has stopped being the main bottleneck.

That usually shows up when:

• the ore tier no longer drives the next upgrade
• collection is already easy enough
• the boulder is producing, but the real blocker moved to progression, bosses, or storage
• extra drills would look satisfying but change very little

That is usually the point where the drill has done enough. Let the ore come in quietly and move the session back to the page that actually owns the next decision.

#What To Open Next After Drill Setup

Leave this page once the rig is producing and no longer needs active attention.

Open another guide when:

• the ore tier itself now needs a direct farming page
• base layout or storage is making the rig awkward
• automation cost is too high for the current progression stage
• the boulder question is really whether to keep, mark, or ignore it

At that point, the rig is done enough. Let it work in the background and move the session back to the next real blocker.

#FAQ

#How do you craft a Drill in Core Keeper?

Current community wiki data lists the Drill as crafted at the Automation Table using Iron Bars and Scarlet Bars.[1]

#Do drills need electricity?

Yes. Drills need power to work against ore boulders; an Electricity Generator powers wires and objects with electricity.[1][3]

#How many drills can work on one ore boulder?

Community wiki data says one to eight drills can be used simultaneously on one boulder, with more drills increasing speed at diminishing returns.[2]

#Should I automate smelting immediately?

Usually no. Start with powered drilling and manual collection, then add conveyors or smelting only when repeated pickups become the real problem.
