• Anderreamer 3D Underreamer


    Our Anderreamer™ 3D Concentric Underreamer allows you to achieve three different diameters for a variety of applications, eliminating your need for two tools. An expandable blade underreamer allows pass-through of a restriction, then enables underreaming at two larger diameters. An enhancement to the Anderreamer tool design, this versatile tool increases safety and efficiency by helping you make fewer trips downhole.
