Deployed in conjunction with a Mill Bit the LiMARĀ® Under-Reamer expands beyond the Mill diameter permitting full bore reaming below well-bore restrictions.
The Mill acts at the first stage creating a pilot hole, the Flo Activated Under-Reamer acts as second stage to enlarge the pilot hole and maximise the effective drift through areas where scale or other well-bore deposits are present. The Under-Reamer is available with specialised reaming blades and mill dimeters to suit all eventualities.
