DTH Rock Drill Bit with Shank SD4/SD5/SD6/SD8/SD10/SD12 for Construction
Product description
A down-the-hole hammer (DTH hammer) is a tool that can be attached to the end of a drill string and inserted into a bore. It's a small jack hammer used to break hard rock into small particles that can be flushed away by the DTH hammer's air exhaust.
DTH Uniform penetration rate can drill to greater depths generally straighter holes safer in broken ground lower noise level longer drill string life
Product Advantages:
1. Rate of penetration of DTH is 2-5 times greater than the rotary
drilling technique.
2. Lesser time consumed compared to when the contractor has to be changed when geology changes.
3. Less wear and tear on the drill bit during drilling operation as the hammer is doing most of the work.
4. DTH requires a minimal amount of rotational torque to cut rock that also allows the hammer to drill straight.
5. Vibrations from the DTH percussive hammer can stimulate the formation to enhance production capability, reducing the need for hydraulic fracturing.
