Product Introduce
A drag bit is a drill bit usually designed for use in soft formations such as sand, clay, or some soft rock. However, they will not work well in coarse gravel or hard rock formations. Uses include drilling water wells, mining, geothermal, environmental and exploration drilling. Whenever possible, they should be used to drill pilot holes because they produce cuttings that are easiest to log.
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.
