Multistate coverage

A Newly Expanded Epiroc Fleet, Built for Scale.

Modern Epiroc surface drill rigs, ready for projects across our multistate coverage.

Fleet

An Epiroc drilling contractor with DTH and tophammer rigs.

On projects with thousands of holes, fleet size and rig condition set the pace of the drilling program. As an Epiroc drilling contractor, we invested heavily in SmartROC, FlexiROC and PowerROC rigs so we can staff multi-rig programs, hold production in hard rock and keep backup capacity close. DTH and tophammer rigs let us match the method to the ground: 3" to 10" holes for construction and 4" to 10" for solar, 4" to 6" seismic shot holes and up to 8" for quarry and open-pit work.

Proven at the top of the range: 10" holes on a 2023 solar project in Upstate New York, and More than 400,000 holes drilled from Texas to New York since 2024. See the projects

Epiroc models in the XCEL fleet.

Official manufacturer graphics and capacity for each model. Hole ranges below are Epiroc machine capacity — not a substitute for XCEL’s project service ranges (3" to 10" construction; 4" to 10" solar; 4" to 6" seismic; up to 8" quarry and open-pit).

Choose the method to suit the ground

DTH vs. tophammer.

DTH Down-the-hole

How it works: A compressed-air hammer strikes directly behind the bit at the bottom of the hole.

Performance: Direct impact at the bit avoids sending blows through the full rod string, helping maintain energy transfer and hole straightness as depth increases.

Typical fit: Larger-diameter and deeper holes, including demanding hard-rock work.

Tophammer

How it works: A rig-mounted rock drill sends impact energy through the drill rods to the bit.

Performance: High penetration potential in favorable conditions, particularly on shorter holes. Rod length and joints influence energy transmission as depth increases.

Typical fit: Smaller-to-medium diameters and shallow-to-medium depths. Also effective in hard rock with suitable tooling.

Both methods drill hard rock. Results depend on ground conditions, bit/tool selection, air supply, flushing and rig setup—not the method alone. These are general method characteristics, not guaranteed production rates or XCEL service limits. Model capacities and XCEL project ranges are distinguished in the introduction above.

Support equipment

Support equipment.

Morooka rubber-track carriers support our operations in rough terrain and harsh environments. Set up with fuel service beds and other support configurations, they keep rigs fueled and supplied across soft, rough and remote ground, so production doesn't stop when trucks can't get in.
