Product Description
Drag bit is used in soft to medium formation such as sand, clay, or some soft rock for water well drilling, mining, geothermal, environmental and exploration drilling. When the DTH hammer or tricone bit lose their effectiveness and then the drag bit is used, the cleaning of the hole is realized by the injection of air or water. They are not suitable in coarse gravel or hard rock formations.
