High air pressure DTH hammer Feature
• High quality alloy steel materials, internal parts with heat-treated technology.
• With various shank hammer type: DHD/COP/QL/MISSION/SD
• With various hammer model: 3.5’’, 4’’, 5’’, 6’’, 8’’
• Using the latest rock drilling theory, optimizing the inside structure and the size of the air distribution, to make the DTH hammer obtain the optimal energy transfer and make it achieve faster drilling speed and lower air consumption.
• The check valve can be replaced to the one with bigger air controlling hole to provide more efficient cutting discharge.
• The top sub and the drive chuck have special thread, which can achieve an easier disassemble.
