Description
We could manufacture all kinds of drill stabilizer used for raise boring machine,
The nominal diameter size is from 9" to 17-1/2", the length is from 48" to 60".
The drill stabilizer could be divided into straight ribs stabilizer ( Tungsten carbide hardfacing )
Straight ribs ( Weld-on hardfacing ) spiral ribs ( Tungsten carbide )
The detail information refer to the below data sheet.
We choose SAE4330V MOD material, Material specification:
