Another World First
AutoStem Micro blasting cartridges are available in 17mm diameter suitable for an 20mm borehole and in 9mm suitable for a 10mm borehole. Power charges range from 3g – 40g making for the widest range of blasting products in the micro-cartridge size category.
We identified a need for a smaller cartridge that could be used without compressors, rock drills, diesel and air hoses.
The AutoStem Micro range was thus designed for applications where our customers prefer to use hand-held electric drills, rather than incurring the cost and labor in using compressors and rock drills.
The cost of rock/concrete breaking using the AutoStem Micro range are in some cases more than 90% cheaper per cubic meter than conventional breaker equipment.
