- The design of hammer
is simplified so as to reduce the number of consumable
parts and
also to let operators easily carry out the hammer assembly/disassembly
operations.
- Kukje Hammer and
bits are manufactured under the server quality control
and manufacturing technology developed by Kukje.
This assures that these products will retain longer service
life under hard conditions.
- The hammer operates
at highest efficiency with a blank choke.
Bypass choke can be used when additional air is required
for cuttings removal through hole.
