JCDRILL CIR65/CIR70/CIR80/CIR80X/CIR90/CIR110/CIR130/CIR150/CIR170 dive bit is made of alloy steel and advanced heat treated high quality alloy steel, which ensures good drilling performance and long service life. It  is widely used by customers all over the world. The use of a wide range:the bit is suitable for carbonate rock, limestone, chalk, clay rock,siltstone, sandstone and other soft and hard. Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance. These are deigned for specific applications for all rock types,hardness's and condition. Medium-low pressure DTH hammer bit advantages

1. The working pressure are between 0.7Mpa and 1.75Mpa
2. Valveless Hammers
3. Simple structure, easy assembly and disassembly, long service life.
4. Higher impulse and faster drilling rate.
5. Lower air consumption and lower oil consumption,A hole can be drilled on the check valve to provide more cutting discharge.
6. Especially suitable for quarrying.
