Tungsten carbide rock drill bits are specially used in core drilling, and the cylindrical steel drill bits are covered by a layer of tungsten carbide. Threaded (screwed) connection core tube and water channel have been designed for it.
The ordinary tungsten carbide bits are suitable for drilling strata (formation) from Ⅱ to Ⅶ grade, and needle-like tungsten carbide bits are quite appropriate for drilling rocks from Ⅵ to Ⅷ grade.
Regarding the packaging, individual bit will be packed in a paper box, and a batch of this kind of bits will be packed in export-standard plywood boxes.
Features of Tungsten carbide rock drill bits:
1.They can be used in drilling complex objects, and high drilling velocity is always available.
2.The blades are made of high-performance carbide, which can greatly reduce the possibility of blade collapsing, as well as ensure good wear resistance.
3.Multi-layer geometric cutting edge is designed to improve its discharging property, as well as to lower its cutting resistance.
4.Various handle shapes are available in order to suit as many drill rigs as possible.
