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.
 

The cutting interface of the DTH hammer bits are loaded with high quality tungsten carbide, which is an extremely hard material. Since hammer bits work with air pressure delivered to the down hole hammer, it is important to use the recommended pressure provided when hammer drilling. Down hole hammer bits come with a wide variety of carbide styles. The sharper the point, the softer formation it is used for. The different styles of carbides on the hammer face include dome, cone and ballistic tungsten carbide inserts which are press fit into the DTH bit.
