Pilot Mills

Pilot mills are recommended for milling washpipe, safety joints, crossover swages and washover shoes. Liner hangers can be milled efficiently, eliminating inside cuts and running spears. They can also be used for cleaning a casing head and suppressing the damaged parts of a casing.

With OTI’s pilot mill, the customer will be able to accurately direct target the fish head, thus eliminating side tracking issues. Circulation holes are positioned such that it facilitates the evacuation of cuttings.

All features if the pilot mill can be customized as per customer needs.
