Drilling Bloomingdale Common Drill Bits Used for Soil and Rock testing

Most people know that geotechnical drilling professionals are concerned with work that involves drilling rigs and drilling projects. Another aspect of geotechnical drilling that many people are not aware of is soil and sediment collection for testing. Geotechnical testing can discover a lot about an area or location that is important for more in-depth drilling. Bloomingdale drilling professionals know all too well that not every drill bit or drill rig is ideal for certain types of sediment and soils. In order to make drilling easier for these geological conditions, drilling professionals will have many drilling bits that work better for specific soil types. Here are some of the more commonly used drill bits for soil or rock testing.

Solid Stem Auger Drill Bits

It is not uncommon for people to not know about different drill bits, but solid stem auger bits are used because they have continuous flight augers which mechanically excavate and continuously transport cuttings to the surface. Unlike other drill bits used in geotechnical drilling, Bloomingdale professionals might use solid stem auger bits because they produce a moderate amount of easily contained cuttings and little or no fluid is required in the drilling process. Because this type of drill bit uses low torque while drilling, it is much easier for smaller drilling rigs to be used. This is great for areas that have tighter drilling spaces such as in residential areas.

Hollow Stem Auger Drill Bits

Hollow stem auger drill bits have a multitude of uses in terms of geotechnical drilling. Bloomingdale professional drilling companies might use these drill bits in areas that are saturated with water, such as during well construction, but they can also be used to collect soil and sediment samples. One of the disadvantages of using a hollow stem auger drill bit is the fact that they cannot go very deep into the ground if a professional needs to see what soil and sediment conditions are like deep underground. Additionally, hollow stem auger drill bits are not the greatest choice for materials that are hard to drill into, and may be better for looser soil conditions.
