The CIR110 features a patented steel valve design that improves working efficiency by at least 20% compared to standard models.
The CIR series is designed for low-pressure operations, specifically between 5 to 10 Bar (working pressure).
It is compatible with bit diameters ranging from 110mm to 150mm using the CIR110 bit shank.
No, the wear sleeve for the CIR series hammers is not reversible. It is designed for specific high-performance orientation.
Yes, the CIR110 is widely used for water well drilling, as well as quarry mining, road construction, and slope protection.
All critical internal components undergo a strict heat treatment process to maximize tool longevity and wear resistance.
