The TD100 is an electric/hydraulic limited access drill designed to safely install cased micropiles and large hollow bar micropiles. The rubber tracks can contract to 48-inches (1219mm) to tram into  difficult drilling positions. The 100HP motor allows the TD100 to operate any drifter or rotary head manufactured by TEI Rock Drills. There are many possibilities with the TD100 and your imagination as a contractor is all that will hold you back when using this powerful little drill.
