Axial Drum Cutters
Axial drum cutters for precise excavation, profiling and surface levelling, with controlled cutting in tunnel, trench and natural-stone work.
HKM axial (vertical) drum cutters provide precise, low-vibration cutting for narrow trenches, concrete column-head trimming, channel profiling and vertical surface leveling. The single-axis vertical drum offers superior control and clean surface quality, especially in tight spaces and vertical cuts.
The AC05-AC30 range delivers fast material removal and short cycle times with a high-torque hydraulic motor, optimized pick placement and a durable gearbox. Easy mounting, practical pick changes and quiet operation are matched by long service life under demanding site conditions.

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.
