Epiroc COP W4 2.0

ROP and reliability

Geothermal and water well drilling are all about speed and durability. The hammer must operate with a high rate of penetration (ROP), while being robust enough for you to drill all the way down to the required depth without interruption. After all, at the end of the day, it's how many holes you've drilled that matters. 

Understanding your challenges

We listened to several geothermal professionals describing their challenges. As a result, the upgraded COP W4 2.0 hammer is powerful enough to efficiently penetrate even very deep or water-filled holes, and its bit durable enough to last up to 400 meters in one go. We know how important it is for anyone working with geothermal or water well drilling. 

More than a facelift

We increased the airflow of the hammer to maximize its impact energy. We redesigned the bit to cope with the increased impact energy. We strengthened the steel of the casing to extend the hammer's lifetime - just to name a few improvements. The upgraded hammer lends its name, COP W4 2.0, to the software world. It's more than a facelift - it's a new way of working. 

Dream Package

We pay equal attention to every part of your equipment. Hammer and bit are developed side by side and optimized as a package – from idea to complete solution. That’s why you can put your trust in COP W4 2.0.

Hammer

We went back to the drawing board when upgrading the existing COP W4. The result? The new COP W4 2.0 HF, with an airflow of 470 liters/s at 35 bar working pressure (505 l/s with cooler) – and the power to penetrate deep and water-filled holes. If you’re opting for the lowest fuel consumption in the market, the classic 420 l/s version comes upgraded as COP W4 2.0 LF, with the same 20 percent increase in wear resistance as the high-flow version.

DTH bit

Our new down-the-hole (DTH) bits are completely redesigned to maximize ROP and durability. The bit’s body is made of a harder and tougher grade of steel. A special heat treatment enhances the bit’s wear resistance and lifetime. The buttons – including innovative Trubbnos – are Enduro Extra treated to further extend the intervals between re-grinds.

E-kit

The internal parts of the hammer last longer than those in contact with the rock. The faster-wearing external parts can be easily replaced. With our economy kit, or E-kit, your COP W4 2.0 hammer can be rebuilt 1–3 times, with little or no loss in productivity. A clever way to cost-effectively sustain the productivity of your hammers.
