ZY26(MZ7665) Rock Drills are suitable for drilling primarily vertical tilting blast holes below the drilling level of medium-hard rock; they can drill blast holes in different directions at different angles after being equipped with FT-100 air leg. Holes with diameter of Φ36~42mm are drilled to the appropriate depth of 1.5~2m and the maximum depth of 5m.
ZY26(MZ7665) is dedicated for coal mine with coal mine safety certification.
