Non-magnetic drill collars which are capable of drilling to the target point without the effect of the magnetic field of the earth are essential products for directional drilling. High strength and high SCC (stress corrosion cracking) resistance are made possible by our original and stable hot-cold work method. Excavation-related products are wideley used in various sites, including petroleum, gas, ore, geothermal, hot spring and tunnel construction.
