Description
Surface drilling applications using tophammer rock drills. Drill bits, threaded drill rods and shank adapters for most makes of rock drill. Includes also tool systems in different dimensions for drilling holes from 51 to 152 mm in diameter, usually to depths of up to 25 meters.
DTH hammers and drill bits are designed to work in perfectly together, giving high penetration rates, long service life and low costs.
Casing permits the simultaneous drilling, running, setting, and cementing of casing while eliminating downhole complexity. Casing techniques are typically used to mitigate hazards when the operator is unable to get through a trouble zone.
