Yes – we have several sets of hollow stem augers: 2.75″ ID (6″ OD), 3.75″ (8″ OD), and 4.25″ (8″ OD) suitable for some of our drills. Though solid stem augers are much more popular because they have better penetration and are much faster for both soil sampling and monitoring well installations, some of our clients prefer to use hollow stems.
In certain circumstances, site conditions dictate that hollow stems are necessary. Depth penetration is generally not as good as with solid stem augers.
