Expandable string mills FKR

Expandable mill FKR is designed for continuous casing section milling throughout the diameter in any interval of wellbore. Expansion of blades, reinforced with high quality composite material, into operating position is provided by the effect of differential pressure in mill body. FKR scope of delivery includes back valve, which prevents tool from sludging during round-trip operations.

Features:

Wear pads preventing loss of diameter;
Hydraulic activation;
Changeable blades;
Capability of using both for cutting-off and for full milling of casing;
Changeable sleeves for different flow rates;
Stabilizers provide additional protection from loss of diameter as well as stabilizing FKR relative casing;
Bottom stabilizer is equipped with no turn system.
