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, and drill a straighter hole.

We produce a variety of tungsten carbide drill bits, mainly ofr water exploration, coal mining and soft rock drilling. Our drill bits are manufactured by casting, precision forging and medium carbon alloy steel machining.
