DTH drill rig in the choice when you need to note the following: First: hard rock drilling larger than reactive. Each pillar drill teeth and are under greater amount of load. Request bit body and columns teeth having high strength. Second: When drilling in Drillability good soft rock drilling faster   relatively large slag best selection of three or four vane airfoil III: Comparative development drilling in the joints broken in When  to reduce skew. The best choice for a good middle-oriented depressed or protruding type drill. Fourth: When rocks containing clay middle slag hole drilling   best choice is often blocked by the side slagging drill. Fifth: When drilling in relatively good toughness  best selection of wedge-shaped rock drill teeth.
