Exploration Core Drilling HQ3 NQ3 Drill Bit Extension Rod
Drill Bit Extension Rod Introduction
it Is uesd for water and gas exploring and injection in underground
coal mine.It adopt special geological steel and advanced friction
welding method with following feature :high strength, stable
welding ,long working life ,ect.
Our thread drill rods are made of high-intensity alloy steel
imported from Sweden. All the trails and threads are formed by high
precision CNC machines. The thread is induced by induction
hardening, then fast heating and cooling. The precision temperature
controlled heat treatment equipment ensures the service life of the
drill rod, improves the mechanical properties of the drill rod,
Holistic carburization increases the carbon content in the outer
layer of drill rod, and hardened outer steel body. The solid thread
can fit perfectly with the inner wall of the drill bits,and
complete various roadway tunneling, underground mining and open pit
drilling task in complex rock and terrain rough drilling with high
precision and high efficiency .
