Deep Rock Galactic – Driller Build Guide & Class Tips

With this driller build guide and tips you’ll be well equipped to deal with groups of enemies and drill through the earth to make useful pathways for yourself or allies. The Deep Rock Galactic driller is one of the four available classes in the solo and co-op mining adventure and sometimes overlooked for the value he can provide.

I consider the driller to be the best coop class in Deep Rock Galactic though and in this guide to building your driller you’ll able to show others the power of a high tier player. As with all builds there will be some aspect of playstyle preferences that goes into creating the best driller build and where this is the case I’ve presented the options with sufficient detail so you can make an informed decision on your build choices for your preferred playstyle. Note though that the driller does have significantly less variation in builds compared to other dwarven classes with a clear winner for most modification tier upgrades.

In addition to the core build I’ll cover some general tips on maximising your role as the driller to take you from beginner to your first Deep Rock Galactic promotion and how to mix and match the best options to ultimately create the ideal driller build for your gameplay style.

Driller Overview

Like many of the classes in Deep Rock Galactic the name speaks for itself when it comes to the driller with your primary goal to drill out paths for your allies to the map objective. When you aren’t creating pathways through the terrain though the driller is a capable fighter alongside the gunner and has fantastic damage and even crowd control depending on your selection of weapons with your perk choice often enhancing these strengths. The driller is a great master of all elements class in the Deep Rock Galactic universe that wants to stay in range of this teammates to protect them and make their lives easier.

You’ll see this reflected in the heavy flamethrower and cryo weapon options that are paired with weaker secondary weapons for backup damage. For utility the driller comes equipped with the powerful satchel charge that can be placed in strategic locations to be later detonated to deal with bugs or simply to clear rocks. Your class utility skill is similarly focused with your large reinforced power drills capable of being a melee weapon if required but are intended for team mobility. The drills are vastly more effective at terrain destruction than your pickaxe although cannot be used for mineral mining.


Driller Specific Tips

The driller is effective across low and high hazard levels with the right focus and use of Bosco in solo gameplay. Utilise the driller tips below to boost your survivability and speed across the various mission and enemy types of Deep Rock Galactic.

  • Your primary goal when playing as the driller is to save your team time, this means looking for potential locations where you can create a tunnel. Tunnels that will be used multiple times are particularly worth the investment and your team will thank you for your efforts.
  • Don’t limit yourself to the horizontal plain when using your drills as they are a highly effective at creating stair like structures that provide a reliable and permanent source of vertical movement.
  • Use your satchel charge early and often, there are many Deep Rock Galactic game types that you’ll know where the swarm and other attacks are coming from so placing one to trigger at the right time can be a team saving action.
  • The driller has the strongest terrain manipulation ability in the game between satchel charge and your drills. Using this to clear firing lines from obstacles or flattening terrain can be a useful advanced tactic that might seem like a minor activity but can vastly boost your allies ability to deal damage and survive. For an advanced (although limited) tactic you can even create bunkers from the environment although you should be careful when doing so and ensure your teammates are on the same page with the strategy.
  • As a driller your role varies heavily depending on your weapon selection. If you’re using the flamethrower for example your goal should be sweeping the area for small enemies to let your team focus on the larger threats. The reverse is true if you opt for a cryo based build though as your focus shifts to controlling the larger enemies and boosting other damage sources against them.


Best Driller Builds Guide

With an understanding of how the driller fits into a role in your Deep Rock Galactic team and some useful driller tips in hand we will now dive into options for building the best driller builds possible. As noted early in this build guide article you’ll have some aspect of choice to consider here as you create something for your preferences and also the particular mission types that you favour or need to complete for your general account progression.

Keeping this in mind the below is a guide to give you direction on the strongest selections that you should be choosing while pointing out the worst options that should be avoided in all cases. Combined you’ll be able to mix all of this information into a build that feels enjoyable and powerful for your own mining adventures.

Driller Primary Weapons

The Driller primary weapons can vastly impact on your role and also a key consideration if you intend to conquer the challenges as a solo or team orientated player. Both are equally viable at their intended role though provided you use them for what they were designed for.

CRSPR Flamethrower: A flame based weapon and the default for all drillers and gives you fantastic area of effect damage and control over the battlefield as you hold down the trigger to lit your bug enemies on fire for additional damage although at a short range in comparison to other dwarven weapons. It also has the unique ability to leave some lingering flame for further crowd control although it’s primarily going to be a direct damage tool with some ability to get under the armoured plates of the stronger foes.

For recommended flamethrower mods you primarily want to focus on boosting the range of the flamethrower as this is one of it’s greatest drawbacks and making the sticky flame mechanic even more deadly.

  • Tier 1 – High Pressure Ejector
  • Tier 2 – Unfiltered Fuel
  • Tier 3 – Sticky Flame Slowdown
  • Tier 4 – Sticky Flame Duration
  • Tier 5 – Targets Explode
  • Overclock – Lighter Tanks or Sticky Additive or Fuel Stream Diffuser


Cryo Cannon: Your second primary weapon option for the driller which becomes available at level 10 and offers a completely opposite playstyle to your flamethrower although both have an element of slowing down incoming attacks. Focused more on supporting your team through damage boosting cryo effects this is not a weapon you’ll want to run when playing Deep Rock Galactic solo and instead reserved for games with at least 2 or 3 other players that bring sufficient damage sources. Building your cannon to reduce wind up time can make it significantly more flexible and pairing that with extended reach and slight boost to damage is recommended.

  • Tier 1 – Faster Turbine Spinup
  • Tier 2 – Overclocked Ejection Turbine
  • Tier 3 – Increased Flow Volume
  • Tier 4 – Hard Mixture or Larger Reserve Tank
  • Tier 5 – Fragile
  • Overclock – Improved Thermal Efficiency or Ice Storm

Driller Secondary Weapons

Driller secondary weapons give you a weapon option with further range than your primary weapons and an alternative method to remove basic enemies from the map. Neither of these pistol style options offer significant damage output though so don’t lean on them heavily to clear paths through your enemies.


Subata 120: Your default sidearm and the option that is easier to use so will most likely be your go to selection. It’s essentially a simple pistol which with the right modifications can see a boost of damage and capacity that make it a reliable side arm and the recommended mods reflect this approach. This means skipping out on the expanded ammo capacity upgrades but given it won’t be your main weapon in most situations is generally not an issue. Tier 5 mods for the Subata 120 has a major decision though and while I default to the Mactera toxin as a counter to flying enemies you can also run Volatile Bullets as a solid DPS boost when paired with your flamethrower although needs some micromanagement.

  • Tier 1 – High Capacity Magazine
  • Tier 2 – Increased Calibre Rounds
  • Tier 3 – Improved Propellent or Expanded Ammo Bags
  • Tier 4 – High Velocity Rounds or Hollow-Point Bullets
  • Tier 5 – Mactera Toxin-Coating or Volatile Bullets
  • Overclock – Automatic Fire or Oversized Magazine


Experimental Plasma Charger (EPC): A fun experimental weapon that is vastly different from the bullet focused weapons that many other dwarves carry. The EPC comes with two firing modes allowing you to shoot single shots or charge up a more powerful attack. Both of these generate weapon heat that will stop you firing the weapon for a short period while it cools down but there is no reloading for this weapon. Damage wise this weapon at base deals nearly double the damage of the Subata 12 and five times the Subata 12 for a charged shot with the trade off being significantly less ammo. There are a few ways to build the EPC and I prefer focusing on strong shots and use the weapon accordingly but you can also build it for a more generalist basic attack sidearm (both options included below).

  • Tier 1 – Higher Charged Plasma Energy or Increased Particle Density
  • Tier 2 – Heat Shield or Overcharged Plasma Accelerator
  • Tier 3 – Crystal Capacitors or Tweaked Radiator
  • Tier 4 – Reactive Shockwave or High Density Battery
  • Tier 5 – Thin Containment Field or Plasma Burn
  • Overclock – Overcharger or Heavy Hitter

Driller Equipment

Your equipment as a driller has briefly been covered above and is primarily about terrain altering options to help your team move around the map to key locations. This support utility should not be overlooked as a good driller can save his team significant time and pain during all hazard levels and game modes.


Reinforced Power Drills: The thing that gives you the driller name is your powerful hand drills that are ideal for clearing dirt pathways but also highly effective in melee range if required. This utility equipment item has simple upgrade options that focus on faster drilling, cooling them down after use and giving you a small uplift in ammo capacity.

  • Tier 1 – Hardened Drill Tips
  • Tier 2 – Magnetic Refrigeration
  • Tier 3 – Supercharged Motor
  • Tier 4 – Increased Tank Pressure


Satchel Charge: With the ability to remotely detonate this satchel charge (or commonly known by the player base as C4). This piece of equipment is equally powerful as a defensive and offensive weapon while also being a terrain clearing powerhouse. In terms of upgrades you’ll be able to pick up some extra damage, stagger enemies and an extra satchel.

  • Tier 1 – Bigger Charge
  • Tier 2 – Kill Switch
  • Tier 3 – Extra Satchel Charge
  • Tier 4 – Concussive Blast

“Mole” Armour Rig: Similar to your dwarven allies you’ll have an armoured rig that you can upgrade to boost your odds of survival. These upgrade options are fairly typical on most dwarves and give you a slight uptick in your survival chances if your shield does break while in the thick of it which is generally where you’ll be as the driller.

  • Tier 1 – Improved Generator
  • Tier 2 – Healthy
  • Tier 3 – Temperature Insulation
  • Tier 4 – Static Discharge


Driller Throwables

Like all classes in Deep Rock Galactic the driller has three options for throwable weapons that each have their different use case to consider in designing your personalised driller build for mining adventures.

Impact Axe: One of the more unique variations of throwable items in the game this axe is deadly on impact damage and allows for up to 8 to be carried giving you the highest amount of throwables. An added bonus is this counts as a melee attack for triggering certain perks and if you miss the enemy it can be reclaimed so you’ll always get full value from your stack of 8. In summary this is a great default option that you can use for most situations without much thought.

High Explosive Grenade: Continuing the theme of high explosive power when it comes to the driller this is for players that want even more opportunities to blow things up. While a solid option with its 6 capacity its generally overkill given your other gear options already ahve amply explosive destruction so would be the lowest on my tier list of driller throwable items

Neurotoxin Grenade: The best grenade for your driller when running with the flamethrower and playing multiplayer as the effectiveness is dramatically enhanced with the option to light the gas cloud on fire. While not offering the damage of the impact axe it can be a viable way to deal with large threats or to protect a revive attempt for an ally.
