Description
FDH SERIES
FDH47DI (4 3/4”)
FDH65DI (6.5”)
DESIGN HIGHLIGHTS
FDH Series is a valve less 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.
FDH Series Hammers maximizes energy output and reduces service requirements.
Wear Sleeve is reversible.
All critical internal components are heat treated under strict control to maximize tool longevity.
EXCLUSIVE FEATURES
Control tube sub assembly is used for guiding piston which minimizes the service requirements.
- Hammer is inbuilt with buffer ring which will sustain the compressive load generated fromdrill string.
APPLICATIONS
• Water Well • Mining • Construction • Quarry
