High Air Pressure Rock Drilling QL50-140mm DTH Hammer Dit
The QL50 DTH (Down-The-Hole) bit is a specific type of drilling bit used in rock drilling operations. It is designed to be used with Down-The-Hole hammers and is commonly used in mining, construction, and geotechnical drilling applications.
Valved drill bits are a type of down-the-hole (DTH) drill bit used for drilling blast holes in mining and quarrying operations. They are designed to work with DTH hammers and are typically used to drill holes in hard rock formations.
Advantages
-
Improved drilling efficiency: The valves help to control the flow of air and cuttings, which improves the drilling efficiency and reduces the amount of time it takes to drill a hole.
-
Reduced wear and tear: The valves also help to protect the bit from wear and tear, which extends the life of the bit.
-
Increased safety: Valved drill bits are designed to be more stable than other types of DTH drill bits, which can help to reduce the risk of accidents.
Applications
-
Drilling blast holes for blasting operations in mining
-
Drilling exploratory holes for mineral exploration
-
Drilling holes for water wells and geothermal wells
