A rock drilling machine with a ~5.9 m propulsion beam refers to a large surface drill rig used in mining, quarrying, or blasting work, where the propulsion beam's length allows extended drilling reach and deep holes.
These rigs are hydraulically powered, mounted on crawlers or trailers, and include compressors and heavy rock drill heads.
They are industrial machines and not handheld tools like consumer rock drills.
If you want help identifying specific models available for purchase, or need technical specifications / how to choose the right one for your project, tell me more about your use case (type of rock, hole depth/diameter, budget).
