DHD360 DTH Hammer with 3 1/2'' API REG for Water Well Drilling and Hard Rock Drilling

Product Description:

In DTH drilling, the drill string rotates while the drilling hammer continuously strikes down into the rock. Inside the hammer, a piston powered by compressed air gives the drill bit its striking power. This combined with the rotational movement means the rock is crushed in a very efficient manner.

Product Advantages:

1.Less amount of drilling fluid and additives are required.

2.Less weight-on-bit allows for lighter rigs that are easier to set up and takedown.

3.Since cutting force is supplied by reciprocal force, the bit encounters lesser deflection and therefore drills more precisely.

4.Rate of penetration of DTH is 2-5 times greater than the rotary drilling technique.

5.Lesser time consumed compared to when the contractor has to be changed when geology changes.
