Mining DTH Drill Bit Black Color Full Size With Shank SD Series
DTH Drill Bit Black Color Full Size with Shank SD Series for Mining
Product description
A Down the hole drilling is the most critical component on a drill rig, and the DTH system has numerous advantages over other options. The top Dth hammer system can provide satisfactory results in stiff uniform rock conditions for short holes, but they will most likely struggle in deep and soft ground with huge diameters.
1. The use of air makes this method very cost-effective as air does not have to be sourced, transported or treated.
2. Less amount of drilling fluid and additives are required.
3. Less weight-on-bit allows for lighter rigs that are easier to set up and takedown.
4. Since cutting force is supplied by reciprocal force, the bit encounters lesser deflection and therefore drills more precisely.
