Features & Benefits

Straightforward controls

Controls with minimal electrical components, bringing you back to the basics with modern technology.

Narrow footprint

This drill is 8.5 in (21.6 cm) narrower in width than the next sized drill in the lineup and can get through a 36-in (91.4-cm) gate or fit on a narrow trailer with other jobsite essentials.

Low sound levels

Low noise emission levels at the operator’s ear of 85 dBa and a guaranteed sound power of 104 dBa makes this drill perfect for installing small utilities in an urban environment with minimal disruption.

More power

Equipped with a 48-hp (35.8-kW) Kohler engine, this drill offers 1200 ft-lb (1627 Nm) of spindle torque and 7850 lb (34.9 kN) of thrust/pullback.

Tracks

Tracks offer ideal traction for operation while providing minimal ground disturbance. This track system design allows a forward ground drive speed of 2.8 mph (4.5 km/h), which is 45% faster than the leading competitor.

Multiple rod options

Equip your drill with either a 6-ft (1.8-m), 1.66 in or 1.31 in (4.2 cm or 3.3 cm) Firestick® drill rod and save time on the job with 180 ft (54.9 m) of on-machine rod carrying capacity.
