STANDARD ROD EXTENSION
Designed for equipment with engines up to 5.5HP. Applied on surveys and drilling in the presence of a large grain size rocks is unlikely. Depth up to 30 meters.
REINFORCED ROD EXTENSION
Designed for equipment with engines up to 6.5HP. It has high mechanical strength for applications requiring high performance. His lowest weight compared to the THICK model allows greater portability. Depth up to 30 meters .
THICK ROD EXTENSION
Designed for equipment with engines up to 6.5HP. It is extremely durable and can work for many years in high-performance requirement conditions. It presents greater weight to the REINFORCED model, so it is recommended for holes up to 10 meters. Depth up to 10 meters.
LIGHT ROD EXTENSION
Designed to power motor with equipment less than 5.5HP, or in conditions with little mechanical resistance performance requirement. Ideal holes environmental monitoring and/or polls in low hardness of land. Depth up to 30 meters.
ALUMINIUM ROD EXTENSION
Designed for Manual Auger Drills. Its design emphasizes portability, applied in large displacement walking situations. It is not recommended for use in motorized equipment. Undefined depth, depends on the terrain, technical and operator experience and evolution of soil compaction at greater depths.
