Photo of the Day: A TEI Rock Drill at the Crazy Horse Memorial

TEI Rock Drills makes pretty cool attachments. The Montrose, Colo.-based company manufactures a fairly awesome MME260 rock drill attachment, which uses their newly patented hydraulic drifters and feed systems. It’s the same attachment you see in this picture, at the Crazy Horse Memorial. When attached to a mini excavator, the drill is used for the detail work on the mountain. TEI Rock Drills are very useful tools for blasting, foundation repair, earth retention and (apparenlty) making amazing sculptures. The patented drifters mentioned above help give full percussion power when fully engaged; this prevents “dry firing” of the percussion unit and a tremendous savings in parts and longevity of the drilling equipment. Pretty amazing stuff.
