Product Detail
HKM DRUM CUTTERS - DC30
HKM DC30 Drum Cutter is a heavy-duty drum cutter developed for 20-30 ton excavators, combining high torque with strong cutting efficiency. Its robust 1,800 kg body, torque of up to 23,000 Nm and optimized pick arrangement deliver excellent performance in thick rock formations and reinforced-concrete surfaces.
Operating with 200-300 l/min oil flow and requiring 110 kW of power, DC30 is built for large-scale projects. Its 64 high-performance picks remove material quickly and evenly while maintaining low vibration to improve operator comfort.
Designed for long service life in mining, road and metro-tunneling projects, DC30 combines a durable gearbox with a maintenance-conscious design to meet demanding excavation requirements in hard ground.
A 650 mm drum diameter, 460 mm single drum width and 1150 mm cutting width provide a broad working surface and high productivity in mining, tunneling and hard-ground applications. The wide cutting geometry enables large areas to be processed with fewer passes on high-capacity carriers.

Frequently Asked Questions
Which excavators is the HKM DC30 Drum Cutter compatible with?
The DC30 is designed for excavators and suitable hydraulic carriers in the 20-30 ton operating class. Final compatibility should also be verified against the carrier’s hydraulic flow, operating pressure and mounting dimensions.
What hydraulic flow and operating pressure are required for the DC30?
The DC30 operates with an oil-flow range of 200-300 l/min and a maximum operating pressure of 315 bar. Required power is 110 kW. For optimum performance, the carrier’s hydraulic specifications should fall within these operating requirements.
What are the single drum width and cutting width of the DC30?
The DC30 has a single drum width of 460 mm and a total cutting width of 1150 mm. These dimensions are important when selecting the right model for the available working width and required surface profile.
What applications can the HKM DC30 Drum Cutter be used for?
The DC30 can be used for mining and tunneling, thick rock and hard-ground excavation, reinforced-concrete work, profiling beneath rail infrastructure, and road or infrastructure rehabilitation. It provides controlled, low-vibration cutting and excavation; final suitability should be assessed according to material properties and site conditions.
