Drum Cutter is a hydraulic excavator attachment that uses rotating cutting drums to mill rock, concrete and other compact materials. It is suited to controlled excavation, trenching, tunnel work, profiling, demolition and surface preparation where a defined cut is preferred.

Drum cutter performance depends on the material, cutter configuration and hydraulic match with the carrier. Selection should consider excavator size, hydraulic flow and pressure requirements, target material, required cutting profile, working space and mounting interface.
