OCMA DrillTech DTH BIT reached the Record of 8000 meters drilled in quarry.
The customer congratulates our company and says:
"After many years of work I have gained a valuable experience in the drilling in quarries. We have tried a lot of bits with various button shapes and of various brands such as ATLAS COPCO, ROCKMORE, SANDVIK, HALCO etc.. and other bits coming from China and Korea. I had never tried OCMA DRILLTECH bits (produced in Italy) before and as a result I have to acknowledge that they are far better than those of the above-mentioned brands. I think OCMA DRILLTECH has reached the top of quality."
