CIR SERIES DTH Hammers Models:
CIR50 / CIR60 / CIR65 / CIR76 / CIR90 / CIR110 / CIR130 / CIR150 / CIR170
CIR series is a steel valve type hammer designed for high performance even at low operating air pressure.
Designed to maximize energy output while significantly reducing maintenance and service requirements.
All critical internal components are heat treated under strict control to maximize tool longevity.
The patent steel valve design significantly increases work efficiency by at least 20% compared to standard models.

A1: The CIR50 features a patented steel valve design that operates efficiently at low air pressure, increasing work efficiency by at least 20% compared to traditional hammers.
A2: It is widely used in mining, quarrying, road construction for blasting work, water well drilling, and anchoring projects.
A3: The CIR50 DTH Hammer is designed to work effectively within a pressure range of 4 to 10 Bar.
A4: No, the wear sleeve for the CIR series hammers is specifically designed to be non-reversible.
A5: All critical internal components undergo strict heat treatment processes to maximize tool longevity and wear resistance in harsh drilling environments.
A6: The CIR50 hammer is compatible with the standard CIR50 bit shank.
