The TD100 is an electric/hydraulic drill designed explicitly for safely installing cased micropiles and large hollow bar micropiles. Its flexible rubber tracks can shrink to a mere 48 inches (1219 mm), making it easy to reach tough drilling spots. Powered by a strong 100-hp motor, the TD100 works well with any drifter or rotary head made by TEI. This drill’s versatile design greatly expands your drilling options.
