Introducing Epiroc ET55, the next step in drill string performance
Epiroc ET55 is the latest addition to our next-generation ET drill string family and is designed as the successor to the trusted ST58 system.
Featuring a shoulder drive connection throughout the entire drill string, Epiroc ET55 helps transfer more energy into the rock while reducing vibration. The design also supports improved durability, easier uncoupling, fewer stuck tubes, and reduced downtime.
For customers currently using ST58, Epiroc ET55 provides a smooth transition to the benefits of the proprietary ET platform.
