• ST-80C 2 Iron Roughneck

    The new ST-80C2 Iron Roughneck incorporates a multitude of improvements based on customer feedback and engineering analysis while still retaining the durability, ruggedness and performance of its predecessor, the ST-80C Iron Roughneck.
    Description

    We are excited to offer the latest version of our ST-80C Iron Roughneck, the ST-80C2Iron Roughneck. The improvements, rooted in customer feedback and engineering analysis, offer better control responsiveness, ease in serviceability and most importantly, operational features that promote rig floor personnel safety.

    Overall Benefits:

    • Enhanced safety features
    • Improved accessibility to many facets of the tool to aid in maintenance, removal and troubleshooting
    • Increased efficiency in repetitive make/break and general tool operations help streamline operations
    • Finer control with improved sensitivity, reactiveness and faster response times
    • Features promote extended life of tool and tubulars
    • Greater structural stability, strength, impact resistance and durability
    • Improved user-interface, user-friendly
    • Tool allows for retrofits into an existing ST-80C floor socket
    • Some ST-80C2 features may be applied to existing ST-80C tools
