Application
For use in moderately abrasive consolidated formations with compressive strength ranging between 140 – 485 Mpa such as hard limestone, quartzite, granodiorite, and medium grade metamorphic formations
Advantage:
1. Strictly select the material to ensure the reliable quality. Bad
steel and tungsten carbide inserts won't be used.
2. Strictly act according to the ISO9001 standard, and control by
full-scale inspection.
3. Sales and support people are highly trained in the latest rock
drilling technology and can offer you expert advice on what
products will best fit a specific end use application.
