high efficiency combined drill bit
Product Detailed
Boring diameter 76,94,110
Coupling dimension 18X18,24X24
The basal body is make of high grade alloy steel for assuring drilling efficiency. Because the drilling depth is usually up to dozens of meters, the strength and toughness of drill bits must be powerful. All the alloy segment is imported from abroada dn selected through nanometer technoloty to ensure and improve the hardness and strength. It adopts low temperature vacuum pervasion welding method to ensure the high efficiency and durable life.
borehole diameter: 42, 44, 50, 76, 82 (mm)
