Products
THREAD DRILLING BUTTON BITS
It conclude normal body,lengthening body and retrac body,which suitable for soft rock, extremely hard rock, corrosive rock, etc. It adopts hot setting button bits technology, optimized design to improve tunneling speed, and numerically controls production to ensure product quality stability, military-grade heat treatment controls requirements and make the products more durable.
TAPER DRILL ROD AND TAPER BUTTON BIT
It need to used different taper degree on the different rock type and rock drills conditions.Taper drills tools has these advantages like faster drilling speed,more straight drilling holes , longer drilling life performance, and lower drilling costs per meter, especially in the mining and quarrying industries.
integral drill steels
The integral drill rods are mainly used for small hole drilling, such as quarrying, construction, tunnel engineering, underground mining, etc., which can reduce the cost of impact energy, increase the drilling speed and efficiency, and it can usually drill holes of diameter 23mm-45mm.
DOWN THE HOLE DRILLING TOOLS
DTH drill bit usually adopts three kinds of head design: flat, convex and concave. It can meet different rock layer types. It is processed by CNC machine tool and multiple heat treatment to improve hardness and surface strengthening treatment to improve fatigue resistance and make drill bit extending the crushed rock life and enhance the drilling performance under the extremely harsh conditions.
COUPING SLEEVES
The coupling sleeve is divided into half bridge type, full bridge type and variable-radius type, and the half bridge type is suitable for high torque drilling rig. Most of the wave thread and step type thread are half bridge type. The full-bridge type can eliminate the looseness of the connecting sleeve along the threaded joint, and the use of the step type thread for better disassembly and firmer connection. The variable-radius is used to convert the thread type and is usually only used in special cases.
