Drum Cutters
HKM drum cutters mill rock, concrete and frozen ground with precision, for tunnel profiling, surface levelling, trenching and natural stone.
HKM drum cutters deliver precise, low-vibration cutting across a wide range of applications, from trenching and tunneling to road profiling and rock breaking. The DC05-DC40 range pairs a high-torque hydraulic motor, an optimized pick layout and a durable reduction gearbox for fast material removal and long service life.
Easy mounting, practical pick changes and quiet operation combine with full 360° rotation so you can trench, profile, demolish and excavate with a single machine. The maintenance-friendly design needs no oil or nitrogen recharging and produces fine, homogeneous particles ready for on-site backfill.

This tool performs a pre-selection based on catalogue values and is not a binding quotation. Attachments without a hydraulic supply, such as rippers, have no flow or pressure rows; those models are unaffected by the flow filter. The final choice is made together, based on material, workload and the hydraulic equipment of the carrier.
