Technical Specifications
Overview
High-Performance DTH Drill Rods
These 114mm DTH drill rods are engineered for demanding rock drilling and piling applications in the mining and construction industries. Manufactured using advanced friction welding technology and integral heat treatment, they ensure efficient energy transfer from the hammer to the drill bit. The surface features a nitrogen treatment for anti-adhesion, making handling easier and extending the service life of the threads in harsh environments.
