Mission40 DTH Bit

 

Underground mining, quarries, hydraulic and hydro-power engineering water well drilling, mineral exploration, anchoring hole drilling, geothermal engineering, subway excavation, and other types of civil engineering all make extensive use of Mission40 DTH Bit. It benefits from high flatness, a smooth hole wall, high drill rod and hammer rigidity, independence from high axial thrust, an unlimited depth of drilling, low device cost, and ease of maintenance.

 

Mission40 DTH Bit Feature：

1. The high wear resistance of Mission40 DTH Bit on medium- to hard-abrasive rock formations is widely recognized. consisting of spherical tungsten carbide inserts, noted for its robust construction against carbide fracture.

2. Suggested as a means of reducing hole deviation

3. Frequently employed tunneling and drifting

4. Medium-hard to hard abrasive rock is best for Mission40 DTH Bit face designs.
