DTH HAMMER

Range : 4 inch - 10 inch

DTH hammer is used for fast and efficient drilling in hard rock formations for applications like water wells, mining blast holes, and geothermal wells. The DTH hammer uses a pneumatic percussion mechanism to deliver rapid hammering blows directly to the drill bit, which breaks the rock efficiently.

DTH BITS

Range : 4 inch - 18 inch

DTH (Down-The-Hole) bits are tungsten carbide-tipped drill bits attached to the DTH hammer. They directly contact and crush the rock during drilling.
Used for breaking and cutting hard rock in water well drilling, mining, quarrying, and foundation work, providing high penetration rates and durability in tough geological conditions.
