Technical description.
The DTH dill comprise a narrow elongated tube which contains an impact piston, internal cylinder, air
distributor, check valve. The real, threaded top sub is fitted with a spanner slot and coupling thread for
connection to the drill tubes. The forward part, the driver check, also fitted with thread, enclose the
splines-equipped bit shank and thansfers feed force as well as rotation to the drill bit. A stop ring limits
axial movements of the drill bit. The purpose of the check valve is to prevent impurities from penetrating
the rock drill when pressedair is shut off. During drilling, the drill bit is with drawn inside the DTH and
pressed against the drive chuck. The piston strikes directly against impact surface of the shank of the bit.
Air blowing occurs when the bit loses contact with the bottom of the hole.
