Proven Quality

For 60 years we've been designing and manufacturing components for rock drills. Our proven designs have been copied but never equaled. Since the first day we opened for business, we didn't compromise quality. We can proudly say that today we still don't.

To us it makes no sense to cut corners when we build our products. Our designs have been tested and proven to work better than anything else. It's a commitment to excellence that comes first and to put a product in your hands that does its job without fail.
