Hollow Stem Augers

Hollow stem augers (hsa's) are recognized as effective drillilng tools for advancing the borehole in a variety of formations.  HSA's are most commonly used in the geotechnical, environmental and construction drilling markets.

After advancing the hsa's to the desired depth, the center plug and rods can be removed. The hollow augers hold the borehole open, thus allowing work to commence inside the auger using soil sampling equipment, down the hole hammers, coring tools, or for installing wells, tie back rods and/or cables.
 
Hole Products offers a complete line of hollow stem augers in sizes from 2 1/4" to 10 1/4" (identified by the auger I.D.) and multiple lengths.  
 
HSA's are available in 2 key and 3 key and standard or heavy duty models.
