Symmetrix - Productivity and precision
Symmetrix is a versatile solution for overburden drilling where ground conditions are difficult, time is limited and precision is crucial. Whether used in ground with big boulders, inclined competent layers or hard bedrock, Symmetrix drills until the required depth is reached. The system drills more quickly and accurately than any other method available today. The unique design of Symmetrix provides reliable results, which saves contractors money.
Elemex – for improved air control
The Elemex Casing Advancement System is the preferred system for minimizing the risk of settlements in surrounding structures. The unique design of the pilot bit directs the air over the drill bit surface reducing the air leakage into the ground. The directed air flushing enables the driller to be in full control of the drilling process.
Symmetrix and Elemex Models
TerraRoc has developed two concepts for Symmetrix and Elemex. Generation 2 allows both Symmetrix and Elemex pilot bits to use the same ring bit set, while Model C allows both permanent and retrievable ring bit sets to use the same pilot bit. This makes product selection easier.
The face design (patent pending) of Symmetrix and Elemex pilot bits improves the flushing of the cuttings and makes the penetration rate even better than before, especially in clay and sand formations. When changing pilot bits, drillers only need one ring bit set for both pilot bits, saving time as well as money. This is an extra advantage when sensitive ground is encountered.
