ST25BR (3.0”)
ST30BR (3.5”)
ST335BR (3 3/4”)
ST45PA (4.5”)
DESIGN HIGHLIGHTS
Stunner Series is a valve type hammers designed for high performance at low operating air pressures.
Suitable bits has a strong robust design without foot valve to withstand heavy duty application.
Stunner Series Hammers maximizes energy output and reduces service requirements.
Wear Sleeve is not reversible.
All critical internal components are heat treated under strict control to maximize tool longevity.
EXCLUSIVE FEATURES
Flapper mechanism helps to adjust inflow air pressure and it is guided with valve centralizer for correct positioning/movement of flapper valve.
Split bush used for guiding the bit and it provided with a groove for easy removal.
Inner cylinder guides piston and supplies air into piston area where the air flow is controlled.
APPLICATIONS
• Water Well • Mining • Construction • Quarry
