The Redbore 50X has been specifically designed for upreaming (blindhole or boxhole) while maintaining a low profile. It is also capable of completing conventional raises. This innovative unit features a retractable wrenching arm, lay-down rod handler, and a drive system with greatly improved transfer of energy, requiring less power during operations.
Nominally, the Redbore 50X is capable of upreaming holes up to 70” (1.8 m) in diameter, to lengths of up to 131’ (40 m).
