Heavy impact. High frequency hammering. Extreme abrasion. Having owned and operated our own mines, we understand how vital the right steel properties are to handling extreme loads in every part of the drill string. This is why every product we deliver starts directly in our steel mills with your specific load case and manufacturing process. And finishes only with the optimal material and format for cost-effective manufacturing of each rock drilling component.
We support all the three areas of rock drilling: top hammer, down-the-hole and rotary drilling. In top hammer drilling, our steel is used for all parts from shank adaptor to the drill bit, also including all part of the drill rods and coupling. In down-the-hole and reverse circulation drilling we also supply to all parts of the drill string, from tubes and end pieces down to all parts of the hammer and bit. For rotary drilling and diamond core drilling we supply to the actual drilling tools, components such as raise bore cutters, tricone bits and legs, PDC bits, diamond core bits and core retrieval systems.
