DHD3.5/DHD340/DHD350/DHD360/DHD380
DESIGN HIGHLIGHTS
1. DHD/QL/MISSION series is a valve less type hammers designed for high performance at low operating air pressure.
2. Suitable bits have a strong robust design without foot valve to withstand heavy duty application.
3. DHD/QL/MISSION series hammers maximizes energy output and reduces service requirements.
4. Wear sleeve is not reversible.
5.All critical internal components are heat treated under strict control to maximize tool longevity.
