Washover shoes are available in three types:

light type (1FK);

medium type (2FK);

severe type (3FK).

Light milling cutters have a toothed cutting end, designed to work on mud cake, sediment, cement and rocks with inclusions of individual small metal objects.

Medium cutters have a wavy cutting surface, designed for the same work as light ones, but with inclusions of up to 15% of metal objects from steel.

Severe type cutters have a massive cutting surface, designed for the same work as light ones, but with the inclusion of up to 40% of metal objects from steel.
