Hydraulically Actuated Mill


The K-Master section mill is a hydraulic downhole tool ideal for milling casing to set rock-to-rock well abandonment cement plugs. The tool performs cut-out and milling in a single operation. K-Master is a simple yet robust design and able to achieve extended-length milling intervals with tungsten carbide dressed arms that provide maximum footage and high ROP.


  • Milling poorly cemented or corroded casing
  • Plug and abandonment operations requiring rock-to-rock isolation

Three cutter arms automatically expand into the milling position when the
K-Master mill cutout arms are fully open.

  • Economical milling, sidetracking, and single-string pipe cutting
  • Multiple cutter arms for optimal milling performance
  • Cutter position indicator
  • Integrated components
