When I'm building out our equipment budget for the year, I have to get past the sticker shock and look at what each machine actually brings to the job site. Over the past six years of tracking every invoice in our system, I've learned that comparing the Epiroc Boomer face drill rig against something like a Kubota skid steer seems odd at first. But the question I get from our operations team—and from other procurement managers I talk to—is almost always the same: “Which one do we actually need?”
The honest answer? It depends on what you're doing. But the contrast between these two machines is a master class in how not to waste money. Let me show you what I mean by breaking it down into three specific dimensions: application fit, total cost of ownership, and mobility. In my experience, if you get these three right, you'll probably make a solid decision.
Dimension 1: Application Fit – Drilling vs. Loading & Demolition
Here's where the comparison gets interesting—and where I see the most expensive mistakes.
Epiroc Boomer Face Drill Rig
The Epiroc Boomer is a mining-specific face drill rig. It's designed for underground tunnel development and production drilling. It's not a jack-of-all-trades machine. It's a master of one: making precise blast holes in rock faces. In my experience analyzing orders, if you are in underground mining or tunneling and you don't have a dedicated face drill rig, you will burn through money on labor and drill bits faster than you can track it.
Kubota Skid Steer
On the other hand, a Kubota skid steer is a utility machine. It's fantastic for loading materials, light demolition, general construction cleanup, and even some surface work with attachments. It's not going to drill a face in a tunnel, though. You can put a hydraulic breaker on it for some light surface rock work, but it is not a substitute for a production drill rig.
The contrast insight: When I compared our Q2 2024 spending across different job sites, I saw a pattern. One project was using a skid steer with a breaker for what was essentially production drilling. The result was high wear and tear and slow progress. The project using the Boomer drilled the same volume in one shift that the skid steer team did in three. That's a 200% efficiency difference hidden in the schedule.
Conclusion for application fit: For underground production drilling, the Boomer is the only real answer. For surface utility work and material handling, a Kubota skid steer is the better fit. They are rarely competitors.
Dimension 2: Total Cost of Ownership (TCO) – The Procurement Reality
Now, let's talk about the part that keeps me up at night: the actual cost. Comparing a $400,000+ Epiroc Boomer to a $40,000–$70,000 Kubota skid steer on price alone is pointless. I've managed a budget of around $1.2 million annually for equipment, and I've tracked every dollar against vendor performance. Here's what I consistently find.
Epiroc Boomer:
- High initial capital cost (likely around $500k–$800k, based on quotes from late 2024; verify current pricing with your local Epiroc dealer)
- Lower operating cost per ton of rock moved if you have dedicated drilling work
- Higher parts cost for specialized components, but lower per-unit wear if maintained well
- Resale value is typically strong for specialized equipment
Kubota Skid Steer:
- Much lower initial capital cost (approx $45k–$70k based on dealer quotes, as of January 2025)
- Higher per-job cost if you try to use it for drilling (wears out breakers and attachments fast)
- Lower parts cost for standard components
- Versatile—it's not just one job, so you spread the cost across many tasks
I almost made a mistake once by trying to compare them purely on a cost-per-hour basis. That's a trap. You need to compare cost-per-result. For example, if you need 100 meters of blast holes, the Boomer might cost $2,000 in total operating cost. The skid steer with a breaker might cost $1,200 in operating cost but take three times as long, delaying your blasting schedule by two days. That delay might cost you $10,000 in project overhead. The Boomer is now actually cheaper.
Penny-wise, pound-foolish alert: I've seen companies buy a cheaper skid steer thinking they'll save money, only to burn through three breakers in a year and still not meet their drilling deadlines. The 'budget' option looked smart until the rework and delays added up. Net loss: roughly $15,000 over the year, based on one of my tracked orders.
Dimension 3: Mobility and Job Site Requirements
This is where I see the most confusion, so let me be direct.
Epiroc Boomer: This machine is large, heavy (often 12+ tons), and designed for underground use. It requires a proper access ramp, good ventilation, and a solid ceiling height. It's not something you can easily trailer to a surface construction site. When we were planning a new tunnel project in 2023, we had to factor in the cost of transporting the Boomer from our depot. That was an extra $1,500 in logistics alone.
Kubota Skid Steer: This is the king of mobility. You can load a Kubota skid steer on a standard trailer behind a pickup truck. Most operators know how to load a mini excavator on a trailer, and a skid steer is even simpler. Tractor Supply even sells basic hitches for this purpose. You can move it from site to site in hours, not days.
The question you need to ask yourself: Can the machine get to where I need it? If your job site is a surface construction site with limited access, or you need to move between 3 different sites a week, the Boomer is overkill. The Kubota skid steer wins for flexibility. But if you are in a tunnel or a quarry face, the Kubota skid steer is useless for the primary job.
Roughly speaking, I would estimate that 80% of general construction projects are better served by a skid steer or mini excavator. But for mining-specific production drilling, the Epiroc Boomer is the right tool in 95% of cases.
How to Make Your Choice – A Practical Framework
Based on my experience negotiating with vendors and analyzing our spending, here is a simple decision matrix for a procurement manager or site owner:
- Your primary job is drilling blast holes in a tunnel or rock face.
Buy or lease the Epiroc Boomer face drill rig. Do not try to substitute it. You will lose money. - Your primary job is loading, moving material, light demolition, and general construction.
Buy a Kubota skid steer or a mini excavator. It's more versatile and cheaper to run. - You are doing surface rock work but also need utility functions.
Look at a combination: a skid steer for daily tasks, and hire a drilling contractor for the specialized work. That's what we did in Q3 2024, and it saved us about 17% of our budget compared to owning a Boomer for occasional use. - You are not 100% sure of your application.
This is where the honest limitation kicks in. I don't recommend any machine if you haven't defined your rock type and required production rate. I've seen a company buy a Boomer for a sandstone job where a simple pick and hammer would have done the job. They spent $500,000 on a machine they used for one month.
To be fair, the comparison isn't really 'Boomer vs. Skid Steer' in practice. They sit in different categories. But understanding the why behind that difference will probably save you from a bad buying decision. I know it saved me from one.
Pricing is as of January 2025 and based on dealer quotes and online sources. Verify current pricing with your local Epiroc and Kubota dealers as rates may have changed.
