The Atlas Copco DM25SP surface blasthole drill is designed for rotary and fast down-the-hole drilling in the hardest of rock. The heavy-duty gear drive on this tough drill delivers precise control at variable speeds without compromising power, while the hydraulic motor feed system on the DM25SP provides smooth, continuous bit loading and rapid feed speeds to reduce drilling costs. This hard-working drill consistently produces up to 40 ft. (12.2 m) or 50 ft. (15.2 m) of clean hole in a single pass, depending on tower selection. Both low and high pressure configurations are available.
