CASING CUTTER

TECHNICAL SUMMARY

A fluid-powered internal casing cutter tailored for well workover and fishing tasks, the ND model differentiates itself with a swappable blade design: one tool (fixed outer diameter) can sever multiple casing sizes by changing blades, cutting the need for multiple dedicated cutters while broadening operational coverage.

Driven by downhole fluid pressure, its blades extend radially to deliver precise internal casing cuts. It fits API connections (2 7/8REG, NC38, etc.) across models like NDD127×102 to NDD406×368, and supports custom blade/thread setups—serving as a flexible, cost-saving option for onshore/offshore casing severance operations.
