DTH hammer bits
DTH hammer bit is also called down the hole tool hammer bits. It is very popular in the world. It is suitable for hard rock formation and have low cost when compared with tricone bits and PDC bits in water well drilling.
Medium-low pressure DTH hammer bit advantages
- The working pressure are between 0.7Mpa and 1.75Mpa
- Valveless Hammers
- Simple structure, easy assembly and disassembly, long service life.
- Higher impulse and faster drilling rate.
- Lower air consumption and lower oil consumption,A hole can be drilled on the check valve to provide more cutting discharge.
- Especially suitable for quarrying.
