Description

Blade type:	Center Drill Bit
type name:	Tungsten carbide oil well drilling bits/ rock drill bits
material:	**0% pure raw material
Dimension:	many size
Place of Origin:	China

The primary tungsten carbide, production equipment imported, compared to the same period *0% higher product life!!
The production of raw materials must be the primary tungsten carbide, otherwise the product appear in sintering process of hole collapse, caused by knife or debris; using from the automatic precision press pressing Germany imported, product density distribution is more uniform; with overpressure sintering furnace sintering, make products better compactness, longer service life of nature!! The service life is long, the tool change times less, high work efficiency, high production efficiency and of course!
