In this regard, Pak Kum Hak, manager of the company, told KCNA:

Their technical specifications confirm with the ISO standards.

Those tools are now widely used at stone processing units, proving economic effectiveness.

The daily capacity of extra-hard cutting tool far surpasses that of imported ones. This tool helps raise the labor productivity in stone processing as the surface of stone cut off by it is smooth. And it makes low noise at cutting work.

The company developed lots of admirable stone processing tools by use of home-made metals and existing equipment.
