RC Drilling Equipment For rock drilling and rock socketing, Berminghammer has a wide variety of equipment available for sale or rent. Berminghammer reverse circulation drilling equipment is suited to all rock drilling methodologies; conventional rotary, down-the-hole hammer or cluster drill. The Berminghammer line of Reverse Circulation Drills were developed in-house by a joint effort of the Construction division and Berminghammer. It is well suited for rock drilling up to 2.5 meters in diameter and pairs seamlessly with Berminghammer’s industry tested lead systems. To understand the advantage of reverse circulation drilling one must understand that direct circulation is limited because the method simply lets water and cuttings come to the surface and spill over the side of the pile free flow to the lowest point in the area. The main advantage of RC Drilling in foundation work is having control output of the spoils (cuttings). This is done by forcing the cuttings back up the inner tube of the drill string and out the top of the drill through discharge hose to the desired disposal location. For use with: Down-the-hole-hammer (sockets and case advancing) Cluster drill Conventional RC bits Advantages: Congested jobsites Environmentally sensitive areas
