Down-the-hole drill rigs(DTH drill rigs) are engineered for hard rock drilling in quarrying and construction applications. Drilling holes of 90-180 mm diameter to 50-meter depths, the DTH drilling machines operate at 1.2-2.5 MPa air pressure. Equipped with hydraulic dust control and modular compressors, these crawler-mounted units handle slopes up to 30 degrees. Their robust design makes them suitable for mining operations, infrastructure projects, and water well drilling in challenging environments.
