 Atlas Copco LHD 23 M rock drill

The LHD 23 M hydraulic rock drill is designed for drilling, blast, anchor and rock-splitting holes. Weighing 54 pounds, the unit provides a high power-to-weight ratio with 48 ft.-lbs. of torque. Energy generated by the drill produces an impact rate of 2,400 to 3,000 blows per minute. Operator kickback is prevented by a built-in torque limiter.
