We are professional AAISI 4145H MOD SAE 4330V MOD Forging Forged Steel Tungsten carbide hardfacing Welding Overlayed raise boring machine drill stabilizer/drilling pipe /stem bars factory from china
Such kind of drill stabilizer surface is inserted by carbide button with high anti-resistance , it could afford
very hard rocks .
It could be devided with Tungsten carbide hardfacing and weld-on hardfacing , we could make according to our customers' requirements.
We could make drill pipes used for raise boring machine, the normial size is from 5"~17-1/2".
The drill pipe has integral type and double pin type. According to the customers' requirements, we could
