Abstract
An abrasive cutter for cutting a rail of a track includes a drive for driving a cutting disc holder in rotation. A cutting disc is attached to the cutting disc holder with at least one clamping element. The drive is directly coupled to the cutting disc holder and has a maximum transverse extent which is at most equal to a diameter of at least one clamping element. The drive has an electric drive motor with a power density PSpez≥0.5 kW/kg. The abrasive cutter allows a reliable, efficient, user-friendly and low-maintenance through-cutting of a rail of a track.
