Center Rock
Our Company
Center Rock Inc. has designed and manufactured rock drilling tools since 1998, when founder Brandon Fisher started the company in Berlin, Pennsylvania. Today we build DTH hammers, bits, LP Drills, and drilling systems used across construction, mining and quarry, oil and gas, geothermal, utility, and water well operations worldwide. Our tools and crew played a central role in the 2010 rescue of 33 trapped miners in Copiapó, Chile, boring the rescue shaft ahead of schedule. We’re ISO 9001:2015 certified, and every tool we build carries the same standard that got those miners home. We make rock disappear.
