The drag bit is the earliest type of drill used in rotary drilling. The drag bit has a simple structure. On the elliptical cylindrical housing with internal thread, a lateral working blade is welded, and the blade is welded with a sheet-like carbide cutting. With the blade warning, the surface of the working surface is welded with a flaky, cylindrical carbide cutting tool and a granular cemented carbide.
