Regular Augers
Regular augers are designed for use in most soil types. Their bits are open to allow entry of small soil clumps as well as relatively small rocks and particles. Regular augers are commonly used for obtaining disturbed soil samples at or near the surface, and for boring to depths where soil samples may then be collected with a separate soil sampler.
Mud Augers
Mud augers feature a laser-cut, open-cylinder design for easy removal of heavy, wet, or clay soils. Their bits are widely spaced to improve entry into sticky soils. Each mud auger also includes two openings in the cylinder wall to make emptying easier.
Sand Augers
Sand augers are built for loose, unconsolidated soil conditions. Their bits are closed and meet at the mid-point, with a restricted opening that helps prevent loss of sampled material during retrieval.
