YT29A powerful pneumatic rock drill
rock drill information
DSL air-leg YT29A rock drills are designed for driving drifts and tunnels . These well-proven rock drills are recognized for their high performance and reliability. They are intended for use for hole diameter range of 34 to 45 mm with Hex 22mm (7/8") shank as a standard. When used with our tapered button bits, penetration rate will improve some 25-50% compared to conventional integral steels and have three to five times longer service life. This drill provides an outstanding power-to-weight ratio.
