First, the tool profile
It is mainly used for grinding and milling the window with the inclined device. It can also be used for other underground milling and milling operations. Using drilling hinge cutting principle design, by the window section, expansion section and polishing section of three parts. Window segment milling out of the casing window, expand the expansion of the expansion section, and finally by the polishing section polishing to improve the quality of the window, a complete window to do all the tasks of casing.
