RMT 120FZ Pneumatic Drifter

RMT 120FZ is another model of Pneumatic Drifter, or we can say another variant of RMT 120F Drifter. Barring a few parts and retainer locking systems, all other parts are the same. While RMT 120F is mostly used for surface drilling, RMT 120FZ is mostly used for underground applications. RMT 120FZ is mounted on rigs like Long Hole Drill Machine (Simba Junior), Crawler Drills, and Wagon Drill. This drifter has a rifle-bar actuated rotation motor with eight pawls (four for each direction) that engage or disengage. The specialty of this drifter is that it can be easily converted from water flushing to air flushing. Used mainly in underground mines, grouting holes for surface mining, construction applications, and drilling and tunneling.
