The Monde MD series excavator drum cutter is the hydraulic rotary-drum milling and cutting attachment designed for operations that exceed buckets, shears and hydraulic hammers: excavation in hard rock and concrete, tunnel construction, asphalt and concrete milling, and underwater works.
With 5 models, MD80–MD450, the Monde excavator drum cutter covers excavators of 3–45 tonnes, with power outputs of 34–140 kW and cutting torques of 3.200–36.000 Nm.
The Monde MD excavator drum cutter is built from NM400, Q460 and Q355 and is available in horizontal and vertical cutting variants, adaptable to the specific application. CE and ISO certified, the Monde MD excavator drum cutter is eligible for public tenders and projects with EU funds in the infrastructure and special construction sectors. The 5 models of the Monde MD excavator drum cutter
The Monde MD excavator drum cutter range covers a wide span of power outputs and tonnages, from 3 tonne mini excavators to 45 tonne heavy excavators. Each model is calibrated in terms of weight, torque and hydraulic flow for the compatible excavator class.

• Cutting torque 3.200–36.000 Nm — power for hard rock and reinforced concrete — the Monde MD excavator drum cutter generates cutting torques from 3.200 Nm on the MD80 to 36.000 Nm on the MD450. The high torque of the MD450 allows continuous milling of high-strength concrete, calcite, basalt and other rocks with a compressive strength of 100–200 MPa, categories of material that exceed the capabilities of conventional hydraulic shears and hammers.
• 5 models for 3–45 tonnes — the Monde MD80 excavator drum cutter (372 kg, 34 kW, 3–8t) covers mini excavators for small tunnels and channels. The MD450 (2.620 kg, 140 kW, 30–45t) is the solution for mining and major tunnels. The MD150, MD240 and MD350 cover the 8–35 tonne classes in civil and industrial construction.
• Rotary drum Ø360–730 mm — adaptable cutting width — the Monde MD excavator drum cutter has a drum diameter of 360 mm on the MD80 and 730 mm on the MD450. The drum diameter determines the cutting width and the penetration depth per pass — parameters essential for designing the excavated profile in tunnels, channels and special foundations. The horizontal and vertical variants allow the cutting orientation to be adapted to the application requirements.
• Horizontal and vertical variants — adapting to the type of application — the Monde MD excavator drum cutter is available in a horizontal configuration (for milling horizontal surfaces — roads, platforms, channel bottoms) and a vertical configuration (for excavating walls, barrette foundations and trenches with a precise profile). The configuration is selected at the quotation stage according to the geometry of the designed excavation.
• NM400, Q460, Q355 — CE and ISO certified materials — the Monde MD excavator drum cutter is built from NM400 (380–450 HB) on the wear surfaces of the drum and the milling teeth, and Q460 and Q355 for the load-bearing structure. The CE and ISO certification guarantees compliance with European quality and safety standards — a mandatory requirement for public tenders and EU-funded infrastructure projects.
• High-performance hydraulic motor — continuous power over long cycles — the Monde MD excavator drum cutter is driven by a hydraulic motor dimensioned for continuous use over long cycles, characteristic of tunnel milling and rock excavation operations. The hydraulic flow of 30–50 l/min on the MD80 and 260–450 l/min on the MD450 is dimensioned to fully use the available hydraulic power of the compatible excavator.
• Underwater applications — the Monde MD excavator drum cutter is designed to operate in underwater conditions too — excavating quay foundations, bridge piers and submerged hydrotechnical works, where other attachments cannot operate or produce imprecise results.
• 60-month UZINEX warranty — milling teeth and wear parts in stock in Iași, guaranteed national technical support within 24–48 hours.
Main applications of the Monde MD excavator drum cutter
Tunnel construction is the reference application of the Monde MD excavator drum cutter. Road, rail and hydrotechnical tunnels excavated in limestone, sandstone, marl and mixed rock benefit from the profile precision of the drum over blasting techniques or the hydraulic hammer, which produce uncontrolled fragments and require additional wall reinforcement.
The Monde MD excavator drum cutter produces a smooth, controlled profile, reducing the need for subsequent finishing works and accelerating the tunnel's waterproofing and lining phases.
Concrete and asphalt milling for the rehabilitation of road infrastructure and industrial platforms is a growing application on the Romanian market. The Monde MD excavator drum cutter mills the degraded concrete or asphalt layer to the exact depth and profile specified in the project, without stressing the underlying layers — a precision impossible to achieve with a bucket or a hydraulic hammer.
Excavating drainage channels, trenches for barrette foundations and precise-profile excavations in cohesive soil and rock is another major application. The Monde MD excavator drum cutter produces a trench profile with smooth vertical walls, reducing the volume of excavated material compared with bucket excavation and minimising disturbance of the soil adjacent to the trench — essential in works near existing foundations.
Surface mining works for the extraction of industrial rocks — limestone, gypsum, salt, lignite coal — represent an application where the Monde MD excavator drum cutter replaces or complements controlled blasting operations in areas sensitive to vibration or near existing buildings and utilities. Mechanical cutting with the drum produces no shock waves and can be used without the security restrictions specific to explosives.
The Monde MD excavator drum cutter also operates submerged — hydrotechnical works (quays, bridge piers, dams) benefit from precise excavation profiles on the bed of the water, without prior formwork or pumping of the work area. Model selection guide — which MD for your application
The MD80 (3–8 tonnes, 34 kW, 3.200 Nm torque, Ø360 mm) is the excavator drum cutter model for mini excavators used in precision work in confined spaces — small tunnels, urban drainage channels, repair milling of pavements and concrete platforms.
The MD150 and MD240 are the excavator drum cutter models for medium civil and industrial construction — special foundations, road rehabilitation, drainage channels with a precise profile, excavations in soft and medium rock.
The MD350 (18–35t, 70 kW, 24.000 Nm) and MD450 (30–45t, 140 kW, 36.000 Nm) are the excavator drum cutter models for major infrastructure projects — tunnels, mining, hydrotechnical works, hard rock milling. The MD450 with 140 kW and 36.000 Nm of torque covers basalt, granite and high-strength concrete (C30/37 and higher). Frequently asked questions about the Monde MD excavator drum cutter
What types of rock can the Monde MD excavator drum cutter mill?
The Monde MD excavator drum cutter covers soft and medium rocks (limestone, sandstone, marl, consolidated clay) on the MD80–MD240 models and medium-hard rocks (compact basalt, friable granite, C25/30 reinforced concrete) on the MD350 and MD450. The maximum processable compressive strength depends on the chosen model and the configuration of the milling teeth. UZINEX engineers confirm the milling capacity for your specific rock type at the quotation stage. Does the Monde MD excavator drum cutter require a special hydraulic circuit?
Yes — the Monde MD excavator drum cutter requires an auxiliary hydraulic circuit with the flow and pressure corresponding to the chosen model: 30–50 l/min for the MD80, and 260–450 l/min for the MD450. UZINEX verifies the parameters of the hydraulic circuit available on your excavator at the quotation stage to confirm compatibility before delivery. Are the drum's milling teeth replaceable?
Yes. The milling teeth of the Monde MD excavator drum cutter are independently replaceable wear components.
