The Redbore 50, has been specifically designed to provide upreaming capabilities (blind hole) while maintaining a low profile. This latest raisedrill offers:
- More accurate and efficient transfer of power
- Multi-directional raiseboring capabilities
- Retractable wrenching arm
- Lay-down rod handler
- Less power required during operation
- Up-to-date, proven, field-tested technology
Upreaming: 28.5 in. (725 mm) – 5.0 ft. (1.52m) diameter with lengths up to 98.4 ft. (30 m). Conventional: 42 in. (1.07 m) – 7.0 ft. (2.13m) with lengths up to 600 ft. (183 m).
