Application

Whatever conditions you're dealing with, our drill bits make the job easier. When hammer drilling, the hammer bit gets its energy from repetitive striking of a pneumatic down hole hammers piston. This hammering with slow rotation drives the hammer bit gradually through ground formations. DTH hammer bits are most commonly used in percussion rotary air blast drilling, mining blast holes, and mineral exploration and water well drilling industries.
