Redbore 100

The Redbore 100 is the crown jewel of the Redbore series of raise drills and is the most powerful, largest capacity proven raise drilling system ever manufactured. When skipping capacity and drift dimensions are of concern, the machine can be fully dismantled for ease of transportation.

The machine features state-of-the-art electronics and PLC controls systems, allowing unprecedented control over the drilling process.

The Redbore 100 can bore raises up to 26’ (8 m) in diameter, to depths exceeding 3,280’ (1,000 m).
