EK 100 | Chain Cutter for Medium Excavators
Heavy Trenching Performance for 18–30 Ton Excavators
- Achieves a cutting depth of up to 1,970 mm
- Offers cutting widths of 600, 700, or 800 mm
- Work efficiently in high-strength ground conditions
- Designed for formations up to 80 MPa UCS
The EK 100 Chain Cutter for medium excavators represents the transition point within the EK Chain Cutters range from high-output trenching to true heavy-duty cutting performance. Built on KEMROC’s patented chain cutting technology, EK 100 is designed for projects where cutting depth, torque, and material resistance exceed the limits of compact-class attachments.
Developed for medium excavators in the 18–30 ton class, EK 100 delivers controlled excavation without impact, allowing operators to work in demanding ground conditions with predictable cutting behavior and reduced vibration. Instead of fracturing material through percussive force, the EK system applies continuous cutting, resulting in clean trench geometry, stable machine operation, and consistent production rates.
With the capability to cut soil, concrete, and medium to hard rock formations up to 80 MPa UCS, EK 100 chain cutter is ideally suited for infrastructure trenching, deep utility corridors, road construction, and heavy civil engineering works where precision and power must go hand in hand.

Why Choose the EK 100 Chain Cutter?
Designed for Heavy Trenching on Medium Excavators
With a rated power of 100 kW, EK 100 chain cutter is engineered to fully utilize the hydraulic capacity of 18–30 ton excavators, delivering sustained cutting performance in dense and abrasive materials.
Increased Cutting Depth and Width Options
EK 100 achieves a cutting depth of up to 1,970 mm and offers cutting widths of 600, 700, or 800 mm, allowing contractors to optimize trench dimensions for large pipelines, cable routes, or foundation works.
Controlled Cutting in High-Strength Materials
The patented chain system allows EK 100 chain cutter to work efficiently in high-strength ground conditions while maintaining low vibration and stable trench walls—an advantage in both open sites and confined infrastructure corridors.
• Maximum torque: 15,700 Nm at 400 bar • Maximum cutting force: 39 kN This performance level enables EK 100 chain cutter to cut through dense soils, reinforced concrete layers, and rock formations up to 80 MPa UCS without loss of productivity.
• Recommended oil flow: 200 l/min • Maximum oil flow: 260 l/min • Maximum operating pressure: 400 bar These parameters ensure EK 100 operates reliably on excavators with high-flow hydraulic systems, even during continuous heavy-duty operation.
• Pick box type: PH 32 HD • Number of picks on cutter drums: 28 / 40 / 48 (depending on width) • Number of picks on cutter chain: 54 • Standard pick: ER 17/75/70/30 Q The reinforced pick system is optimized for abrasive and high-strength materials, ensuring long tool life and consistent cutting efficiency.
With an operating weight between 2,450 and 2,620 kg, EK 100 chain cutter provides the mass required for stable cutting on medium excavators, improving penetration control and reducing unwanted tool deflection.
Main Applications of the EK 100 Chain Cutter for Medium Excavators
Deep Infrastructure and Utility Trenching
EK 100 is ideal for large-diameter pipelines, high-capacity cable routes, and deep utility corridors, where wide and deep trenches are required with precise geometry.
Road and Civil Engineering Projects
The attachment efficiently removes concrete road structures and heavily compacted layers, preparing surfaces for reconstruction or reinforcement.
Selective Excavation in Rock and Concrete
The continuous cutting process allows precise material removal in rocky or reinforced environments, minimizing overbreak and supporting controlled excavation.
Trenching in Medium to Hard Rock
Designed for formations up to 80 MPa UCS, EK 100 performs reliably in limestone, sandstone, calcium carbonate, and similar materials where conventional trenching tools struggle.
FAQs – EK 100 Chain Cutter for Medium Excavators
What excavator size is EK 100 designed for?
