Down-The-Hole Drill, usually called DTH, is mainly a pneumatic powered rock or ground drill, in which the percussive hammer is located directly behind the drill bit, so the percussion mechanism follows the bit down into the drill hole. The drill pipes transmit the necessary feed force and rotation to the DTH hammer and bit, as well as compressed air for the DTH hammer.
Down The Hole Bit, usually called DTH bit, is used with DTH hammers for drilling holes through a wide range of rocks types.
In conjunction with DTH hammers, DTH bits are designed with a splined drive for rotating the bit in the ground.
Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.
Our variety of DTH bits are manufactured using high quality materials to provide you with a fine balance between penetration capability and bit life.
We offer a comprehensive range of standard and made to order drill bits on an extensive selection of shanks with a wide variety of head designs to suit every project.
