Product Description

DHD360 Quarry Mining High Air Pressure DTH Hammer

DHD SERIES DTH Hammers

Model Range: DHD3.5 / DHD340 / DHD350 / DHD360 / DHD380

DESIGN HIGHLIGHTS

DHD/QL/MISSION series is a valve-less type hammer designed for high performance at low operating air pressure.
Suitable bits have a strong robust design without foot valve to withstand heavy duty application.
DHD/QL/MISSION series hammers maximize energy output and reduce service requirements.
Wear sleeve is not reversible.
All critical internal components are heat treated under strict control to maximize tool longevity.

APPLICATIONS

These hammers are widely used in mining, quarrying, and road construction for drilling and blasting work, as well as water well drilling, slope protection, anchoring, and more.
