TEI manufactures two sizes of electrically powered and limited access drills designed to safely and quietly install micropiles and grout holes. All models of TEI patented drifters or rotary heads can be matched with our TD75 or TD100 Electric Track Drills. This wide range of electric drilling power makes limited access drills perfect for operating through narrow or low entrances/exits, under buildings, or in tunnels and mining applications. The TEI Electric Track Drill requires no separate power pack, reduces noise and fumes and removes the need for bulky hydraulic hoses throughout the drilling area.
