KAT DRILLING
1 / 1
Designed for high performance even at low operating air pressure, ensuring maximum efficiency during drilling operations.
Features bits without foot valves to withstand heavy-duty applications and extreme quarry environments.
All critical internal components are heat-treated under strict control to extend the tool's service life.
These hammers are widely utilized across various industrial sectors including:
Mine, quarry, road construction for drilling and blasting work.
Slope protection, anchoring, and foundation work.
Efficient water well drilling in diverse geological formations.

A: The QL60 is engineered with a valve-less design and heat-treated internal components that allow it to operate efficiently under high air pressure while maintaining structural integrity.
A: Yes, the QL series DTH hammers are widely used for water well drilling, as well as mining, quarrying, and road construction.
A: No, the wear sleeve for the DHD/QL/MISSION series hammers is designed to be non-reversible to ensure specific performance standards.
A: For the QL60 model, the optimal bit diameter range is between 158mm and 190mm.
A: The QL60 DTH hammer typically uses an API 3 1/2" REG PIN for the top sub thread connection.
A: The valve-less design maximizes energy output and reduces the frequency of service requirements, allowing for more continuous operation in heavy-duty applications.
