ROLLERISED ROTARY CUTTER

The LiMARĀ® Rollerised Rotary Cutter is designed to drop, cut and clamp onto the wireline when a toolstring becomes inadvertently stuck down hole.

Utilising the fundamentals of the industry proven rotating knife technology, the Rollerised Rotary Cutter has been positively refined to further improve performance.
The LiMARĀ® Cutter reduces exposure time around the wireline valve during assembly, increases the likelihood of reaching target depth using integral rollers along with further enhancements on the cutting technology to cleanly and more effectively sever the stuck wireline. The integral roller diameter has been specifically optimised so it is large enough to be deployed in various completions so as not to pass the toolstring to be fished.
