With the CME-55, benefit from the essential torque required for auger drilling, as well as rotation speeds that surpass 740 rpm for rotary or core drilling applications. Additional optional combinations of rotation speed and torque are also offered, including a high-torque rotary drive that provides 13,225 foot-pounds (17,930 Nm) of torque. Equipped with five forward gears and one reverse, this system ensures a suitable rotation speed and torque combination for nearly any drilling scenario. The transmission is connected to the drill engine through a robust 13-inch (33 cm) clutch. Moreover, the design ensures that the transmission remains stationary in relation to the spindle, thereby facilitating seamless gear changes even while at the top of a feed stroke.
