The Modular Sandmole offers extra long flighting for use in unfavorable sand conditions where a cave-in is possible. Generally, a front section is used along with one back section to create a 37" long Sandmole. For better performance, you can use additional back sections to increase length, pull and stability. They each feature a diameter of 1.5". Use of a Lead Auger behind these Modular Sandmole Compaction bits really helps make a tight, clean hole by moving out the excess material from the drilling. Front and back sections are machined from solid chrome-moly alloy steel billets for strength and stability. Each section is heat treated to an average tensile strength of 150,000 psi.
