Heavy Duty Mill




Mill is a kind of special fishing tool, which is used to mill and cut junks in the hole so as to handle with down-hole drilling accidents. Our Heavy-duty mill adopts long cutters which are welded with bottom part together by the advanced technique of integral sintered, and prolongs its life effectively. It has the configuration of three asymmetry distribution waterholes according to fluid mechanics principle in the bottom part which can form unsymmetrical bottom-hole flow field, therefore it cleans the bottom hole and increases the capability of cutting and milling remarkably. According to the Mill shape, there are Flat-bottom Mill, Concave Bottom Mill; Blade Mill and fishplate mill, etc.
