DITCH WITCH TRENCHLESS SYSTEMS
ALL TERRAIN AIR HAMMER
Ditch Witch® All Terrain directional
drills are so named because they
perform with exceptional efficiency
in the widest range of ground
formations, from mixed hard soil
to cobble to solid rock. Equipped
with the All Terrain Air Hammer,
Ditch Witch All Terrain directional
drills expand this range to include
the hardest of rock—20,000 psi
and up. More important, the
All Terrain Air Hammer expands
your productivity.
KEY FEATURES
• Compatible with Ditch Witch®JT4020 All Terrain and JT100 All
Terrain directional drills, the All Terrain Air Hammer quickly and
cost-effectively cuts through the hardest rock.
• Advanced technology enables the All Terrain Air Hammer to
continuously drill as it is being steered, an exclusive All Terrain
drill feature that results in superior productivity; other air
hammers require stopping the drill rotation to change directions.
• Both the JT4020 All Terrain and JT100 All Terrain have standard
cruise control that maintains thrust and rotation settings, which
reduces operator effort and increases productivity.t
• All Terrain Air Hammer is designed to penetrate rock of 20,000
to 35,000 psi and harder, where rotary units and mud motors
lose effectiveness.
• Minimal cost of spoils cleanup: used properly, the All Terrain
Air Hammer leaves only dry cuttings and a relatively small
amount of foam used downhole to remove cuttings.
• Peak performance is achieved when used with the Rockmaster
Air Housing (included in All Terrain Air Hammer kit), which
features larger air ports that help increase production.
• A very low flow rate—4 gpm (15 L/min)—means low fluid costs.
• Unlike other air hammers on the market, the All Terrain Air
Hammer requires no oiler or drilling mud, which reduces overall
cost of production (severe cases may require a foaming agent
in the water).
