If you've ever ordered an Epiroc drill rig and felt that nagging doubt when the quote arrived — like “Is this really everything I need?” — you're not alone. I've been handling equipment procurement for mining and construction companies for six years. I've personally made (and documented) 11 significant mistakes, totaling roughly $26,000 in wasted budget. Now I maintain our team's checklist to prevent others from repeating my errors.
This story starts with a single order: an Epiroc SmartROC T40 drill rig, plus a matching rock drill. Nothing complicated, right? Until I learned the hard way that the most expensive number on a quote is never the upfront price.
Surface Problem: The Quote Looked Good — Too Good
We needed a new drill rig for a medium-scale quarry expansion. I'd done my homework. Epiroc's reputation was solid; their DTH and top hammer technology were exactly what we needed. I contacted three dealers, compared specs, and settled on a package that included the rig, a COP 66 rock drill, and a basic service kit. The price was $372,000, which was within budget. Delivery in 10 weeks.
I placed the order. Felt good. Checked the box. Then reality hit.
Deeper Cause: What I Didn't Know I Didn't Know
The problem wasn't the drill rig itself. It was everything around it. Here's what the quote didn't include:
- Air compressor — The T40 needs a high-volume air supply for the DTH hammer. I assumed the existing site compressor would work. It didn't. We needed a Dewalt air compressor rated for continuous duty (or equivalent). Add $8,500.
- Generator — The rig's electric panel required a separate power source for auxiliary systems. The site generator was already at capacity. We sourced a Honda generator (the one everyone recommends for reliability). Add $4,200.
- Drill steel and bits — I'd accounted for a few, but not for the full set of sizes needed for different rock conditions. Another $3,600.
- Transport permits and site prep — The rig is heavy. Road permits, crane rental, reinforced ground pads. $6,200.
Total surprise cost: $22,500. And that's before the delay. The compressor didn't arrive for 3 weeks because I ordered it after the rig landed. The generator needed a special fuel filter we didn't stock. Meanwhile, the rig sat idle. The project timeline slipped by 11 days. The production loss? We calculated $37,000 in lost revenue.
The Real Cost of Hidden Specs
Why do these hidden costs happen? Because the vendor's job is to sell the rig, not to manage your entire site. They assume you know your auxiliary equipment needs. But I didn't. I fell into the trap of thinking the quote was the total cost.
In September 2022, after the third rejection of a similar order (different product, same pattern), I created our pre-order checklist. It now includes 47 line items, from compressor CFM requirements to spare parts storage. In the past 18 months, that checklist has caught 17 potential errors, saving us an estimated $63,000 in rework and delays.
"I've learned to ask 'what's NOT included' before 'what's the price.' The vendor who lists all fees upfront — even if the total looks higher — usually costs less in the end."
The Solution (Short, Because You Get It Now)
Here's what I do now for every Epiroc drill rig order:
- Get the full spec sheet — Not just the rig, but every connection, power requirement, and optional accessory.
- Walk through the entire installation process with a site engineer — Not a sales rep. The engineer will flag things like "that compressor won't reach."
- Ask for a "turnkey" quote — Even if it costs more upfront, it forces the vendor to surface the gaps. If they refuse, red flag.
- Budget 15% over quote — For ancillary items you didn't think of. I call it the "5th grader tax." Because let's be honest, sometimes we miss the obvious — like whether a simple 5th grader could point out that a generator needs fuel. (And yes, I've been humbled by those questions.)
Prices as of January 2025; verify current rates. Epiroc drill rig pricing varies by configuration. Dewalt air compressors and Honda generators are examples only — always match specs to your specific rig model.
