Full Safety, the distributor of Robit Group, carried out a successful test with Robit consumables at El Teniente copper mine in Machalí, Chile. 

​The test was conducted for Jumbo drilling on a Tamrock Axera Jumbo with HLX5 drifter by using the following Robit consumables: R32x45S1 bits, HEX35 C38-R32 14′ drifter rod and coupling C38-C38.

The bits averaged out 315 meters without grinding. As for the drifter rod and couplings averaged out 1 724 meters. The meterage is always relative to the rock, the conditions of machinery and operator skills including pressure management.
