Taking blast hole drilling to a new dimension Secoroc COP 66 - Shorter. Lighter. Faster.

Customer comments on Secoroc COP 66 "The operators told me that they like it because it's not that heavy and it's short. It's easy to handle and more user friendly to service it. From the production side, the penetration rate is around 15% faster! The operators wonder when we are switching from COP 64 Gold to COP 66!" Venter: Peter Finter (owner) South Africa “That hammer you have there, ticks all the right boxes, huge plus, absolutely” Capital Drilling: Tony Woolfe (Group Asset Manager) “It is very easy to maintain. And the feedback we had from the guys and what is very important to me is the penetration rate. The penetration rate went up from 16 to 21 meters per hour, 20%! That is a lot for us.” Na-Sera: Pierre Lang CEO South Africa

COP 66 & SmartROC D65 – A perfect marriage Perfectly matched to the SmartROC D65 rig Superior performance on any other drill rig Reduced air consumption vs. COP 64 Gold Works more efficient on high altitudes Sustained performance through hammer life cycle

High altitude influence Altitude factor: 15% / 1000m 470l/sec at sea level gives 385l/sec at 1500m altitude Example COP 64 Gold will hold 21 bar Net penetration 0,63m/min COP 66 will hold 26 bar Net penetration 0,77m/min 22% higher penetration rate That’s “PEAK” PERFORMANCE!

TCO Concept (Total Cost of Operation) The TCO-calculator is a tool that will help you to calculate the total cost per engine hour & per drill meters It can also calculate the capacity per year in tons and in drill meters What is aimed at with the tool is to have it on one page, user friendly and quick to fill in The results will only be as correct as your inputs Take the opportunity to compare COP 66 to your current solution!
