Ditch Witch All Terrain Air Hammer
All Directional Drills
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 production is extended into the hardest rock category. More important, the All Terrain Air Hammer expands your productivity.
Equipment Features
Featured Content
Unlike other air hammers on the market, the All Terrain Air Hammer requires no oiler or drilling mud, which reduces overall cost of production. All Terrain Air Hammer is lubricated by water and able to work in even the most sensitive environmental areas.
Complete kit includes: All Terrain Air Hammer; convex bit, bit jaw and jaw assembly; two slide pins; Rockmaster Air Housing; and a fluid pump and air adapter kit.
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.
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.
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.
A very low flow rate—4 gpm (15 l/min)—means low fluid costs; a patented hydro cyclone features an impeller (rotor blade) that reduces that amount of fluid in the Air Hammer and on the jobsite.
