This type of bit is used for making large cut holes in drifting and

Description A drag bit is usually designed for 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. Three-wing bits tend to drill faster, whereas four-wing bits are longer-lasting, more durable,
