Mills Machine offers two types of Soil Sampling Systems ranging from the simple and inexpensive to the more complex and time-saving system. Our full range of Hollow Stem Augers and Hollow Stem Auger Accessories make it possible for you to accomplish all of your sampling needs.

1. Standard Intermittent Sampling.
This method uses standard hollow stem augers and normal interior drill rod. As sampling is required, remove the interior drill, attach a split tube sampler, and drive it into the ground with an above-hole 140 lb. sample hammer, or if the sample is deeper down, an in-hole 140 lb. sample hammer.  When the sampler is full, remove the drill rod, retrieve the sample, and reinsert the drill rod and pilot bit to continue drilling to the next zone to be sampled.

Components for this type of system may be purchased individually or your Mills Sales Representative can put together a package of parts that will make up a complete system.

2. Standard Continuous Sampling.
This method uses drill rod for continuous sampling, along with a modified, longer drive cap and a five-foot sampling tube. The drive cap has adjustment holes for easy adjustment at any time, as soil conditions vary, or for proper positioning of the sampling tube behind the cutterhead, even with the cutterhead, or in front of the cutterhead.

Below the rod-to-cap adapter, a bearing assembly is inserted to prevent the sampling tube from rotating and shearing the soil sample. The five-foot split-sampling barrel is pulled from the hole every five feet and an empty split barrel inserted. In normal operating conditions two split barrel tubes are required.
