Product Description:

Drag bit are manufactured from forged high-quality alloy steel and hard alloy, plus state of art welding technology and multiple precision heat treatment to provide the highest penetration rate and longest lifespan at the roughest condition.

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.
