Solid Stem Auger System

Polaris’ Solid stem augers (SSA) are drilling tools consisting of a solid central steel shaft with continuous helical flighting welded to the exterior. They are used to mechanically cut soil and transport cuttings to the surface via the rotating spiral.
Key Features and Specifications
Design: Features a solid central core (unlike hollow stem augers), making them structurally strong and efficient at displacing soil laterally.
Soil Suitability: Primarily used in stable, cohesive soils (like clay or glacial till) that can maintain an open borehole without collapsing once the auger is removed.
Drilling Depth: While generally used for shallow applications (under 30 metres), larger rigs can reach depths of up to 400 feet in semi-consolidated formations.
Diameter: Standard sizes for environmental rigs range from 4 inches to 6 inches, though specialized industrial augers can reach up to 24 inches.
Connection Type: Typically features hex shanks (pins) and hex sockets (boxes) to connect multiple five-foot sections into a single string.
