Lone-Star - Hollow Stem Augers

For sandy or loose soils, our hollow stem augers collect samples without the risk of contamination from the surrounding unstable soil. The augers are available in 6- and 8-inch diameters and feature a 2 ¾-inch or 3 ¾-inch internal diameter. The center rod and center plug can be removed to create a clear path for inserting a soil sampler.
