Product description

FlexiROC D55 is an equally versatile and efficient down-the-hole drill rig that keeps your production up and your costs down. Thanks to its flexibility and overall drilling capacity, it’s just as perfect for quarry blast hole drilling as for mining operations. The precise DTH drilling empowered by our unique cylinder feeding improves blasting, and running at lower rpm means longer engine life, less fuel consumption and low lifetime cost. The reliable design keeps the rig where it belongs: in the quarry.
