* High Grade Steel Plate * 4140 Heat Treated Alloy Steel Hex Connectors * Auger outside diameter is designed for the heavier wall casing to limit the trimming of auger if thicker casing is specified * Auger Bushings on 5″ Hex Augers are reinforced with heavy duty gusset rings to increase strength as connection points
Auger Strength
- Auger Sizes 4”-96” diameter
- Equal to or greater in Torque Capacity, more Inertia-Strength with thicker wall tube. Less Twist equals Longer Life to handle Cyclic loading.
- Heavy wall auger tube exceeds the typical wall thickness used by the competition to meet the high torque produced by MBM auger boring machines.
- Custom auger available for commercial and industrial applications.
Auger Tube Wall Strength Increase for Twisting
