3" To 17 1/2" , 3 Wings 4 Wings Drag Bit For Water Well Drilling

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, and drill a straighter hole.

Drag bits features:

1, A solid one piece heat treated, 4140 alloy steel body for bit strength & durability;

2, CNC threaded machining for proper installation &use;

3, Forgings are milled to better seat the carbide inserts.

4, Select tungsten carbide inserts 5.5mm thick are standard.

5, Relief is hand ground behind carbide inserts for maximum performance.
