instructions on labels and in material safety data sheets
(MSDS).
Overview
The All Terrain Air Hammer is designed for use on
directional drills in hard rock applications. The air
hammer uses air pressure to create percussive force,
which drives cutting inserts into rock. After the “drive” air
has produced impact, it is expelled as “return” air that
removes cuttings. Foam mix injected into the bore
through the drill string is used to suppress dust and clean
the bore.
Prepare Foam Mix
The manufacturer recommends the use of Baroid Quik-
Foam® foaming agent (p/n 255-1023) to improve hole-
cleaning capability of the airstream and reduce dust
during drilling.
As a general guideline, use 0.25-1 gal (0.9-3.8 L) of foam
agent for each 100 gal (379 L) of water.
For more information, see the instructions for foam
drilling system mixtures included with the foaming agent
or contact your Ditch Witch dealer.
