Description

If you need to bore a small diameter tunnel in hard rock where line and grade are critical, Robbins offers Motorized Small Boring Units (SBU-Ms). These machines have been specifically designed for long bores (over 500 ft/150 m) with difficult ground conditions. They are offered in cutterhead diameters from 48″/1.2 m to 78″/2.0 m. If you are not familiar with SBU-As, we suggest you read about them before researching SBU-Ms.
