Western Drilling stocks and supply's DTH Hammers for all major DTH Hammer brands and shanks. When percussion or hammer drilling your choice of hammer bit is just as important as your choice of down hole hammer. DTH stands for “down the hole”. 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.
